Okay, we'll start on the next rabbit hole - music.

It's always been super important to me despite never having played an instrument. When I was 13 we lived on a ranch 16 miles from town and had no phone. We did have a stereo and a bunch of records but it was a lot of folk/hippie music (sorry Cat Stevens - I still love you but...) and so one day I decided to see if I could connect to the larger world and rigged up wires from the stereo to the TV antenna (I had no clue) and I found a station 75 miles away in Colorado Springs and they played "alternative" music; David Bowie, Art of Noise, Men Without Hats, Devo and I was thrilled. Up until then it was all country music.

i-BhzPCzN-X2.jpg

Fast forward to college and girlfriends that wore flowery dresses with Doc Martin boots and listened to the Cure, Depeche Mode, Robyn Hitchcock. I wanted to own this music and so I needed to buy my own stereo. I went to a bunch of stores and tried to make sense of the equipment and the slick salesmen trying to get you to buy something because this unit had less THD and more watts per channel.

It was confusing.

Then I happened by a store called Audio Alternative. I liked the the "alternative" part and the fact that it looked like a home and not a speaker warehouse. I went in and met Rick Duplisea who asked what I was looking for - a stereo. He didn't sell stereo equipment he sold "hifi" and was busy but how about coming back tomorrow when he had more time? But first, have a seat here and listen to this; and he put on the album Two Wheels Good by Prefab Sprout who I'd never heard before and he blew my mind. The music came from nowhere - not the speakers but from the space around them. Each instrument was clearly defined at a place in space in three dimensions and it felt alive and real.

I came back and bought a hifi from Rick. Then I came back to just visit Rick and listen to music. When I could afford to make an upgrade to my little Rotel integrated amp I would trade up. Rick introduced me to the idea that specifications don't translate to sound - to the idea that if something sounds better than it is better. Because that's what you do in the end - listen to music. Really listen.

Eventually Rick hired me to work at the store and it was one of the best jobs I've ever had in my life. I lived to find more music, new music and different music.

When I finally left I'd upgraded myself to a very great system including a beautiful Linn LP-12 turntable. This was when CD's had just come out so records were cheap and I bought them all the time. My collection grew and grew.

When I moved to NYC I had my albums shipped a few years later - 10 70lbs boxes. I kept moving those albums over and over. Eventually I wasn't listening to them as much because you couldn't get new music on vinyl and I decided to sell my turntable for $2500.

But I kept the records. With no way to listen to them. And I moved them again and again like a giant anchor around my neck. Finally they moved to Oregon and were stored in Judiaann's sisters barn. Then the cottage. Never played. At several points I thought about getting rid of them - all music was digital so why bother?

Nadia asked what they were and I tried to explain how a record worked and why I had so many of them but I had no way to play them.

i-Pjb7Srw-X2.jpg

So I bought a Rega 3 - the first turntable I owned. It sounded awful. I was sad I'd kept the records. I thought it was the cartridge and so I tried a couple and it never sounded good.

i-4V84rXq-X2.jpg

So last spring my friend Tom visits. He'd fallen down the hifi rabbit hole the year before and bought a beautiful Naim system - basically a 20 year newer version of what I already owned. We did some trading for an espresso machine I had no room for and when we plugged it in and put a record on it was magic.

i-VvN3Qzb-X2.jpg

I think the phono section of my old amp was bad and that's why it sounded fine when streaming but awful with vinyl. But now it was all different - records, vinyl, sounded absolutely amazing. Everything about the magic of vinyl came back to me.

I brought the records in from the cottage. Nadia, Lucas and I took a month to alphabetize them again. We stopped streaming music and started to play records. Nadia invented a game: pick a letter and a number. F 22 = Fine Young Canibals, J 11 = Jefferson Airplane, R 33 Roxy Music.

i-rWp2Jtc-X2.jpg

We've stopped watching TV and spend our evenings playing music, drawing or playing games. It has been single greatest thing that has happened in this past year - I have music back in my life. Not as a background while I work but as an active thing that I'm curious about and that I share with Nadia who is far more into the music than Lucas is right now.

The records took over the house for a while this fall as they were alphabetized they eventually found a home in the china cabinet - which is now the record cabinet. But the shelves were sagging because records are heavy.

i-k5dJSX4-X2.jpg

I found just enough birch ply in the scrap to make some dividers that I screwed to the shelves.


i-GGbRFbR-X2.jpg

In addition to playing records Nadia and I are sharing interest in finding new music and one of her favorite artists is Arlo Parks. I bought tickets to that show but discovered the week before it was a 21 and over and we didn't go. Her other favorite artist is Aldous Harding and that was an all ages show so I took her and Lucas this summer.

As first shows go I don't think it could have been more special.

We got to McMenamins Crystal Ballroom early as it was a general admission show. I explained that meant we didn't get seats but stood, anywhere. If you liked a band you wanted to be close. We worked our way through the crowd and at the front an older couple saw Nadia and Lucas and made room for them at the front row!

The show was amazing. Aldous is a quirky, funny performer that plays soulful music. She has a stern, focused stage presence. When she'd play a song Nadia knew she'd turn to in complete surprise and say, "Oh my god! She's playing that song". At one point, during an intense guitar solo, Aldous had her head down, concentrating and looked up at the crowd, saw Nadia, and smiled right at her.

Nadia practically fainted. Best first show ever.

i-Zfc3JQj-X2.jpg

The biggest change since the separation is that music is the focus of the house and not screens. We play records, talk about bands and draw during the week. We still have pizza/movie night on Friday but that's the only night with TV. I can't really explain how much of a fundamental change that is. And also how amazing it is to have music in my life again.

The other thing that's amazing is that, while I was gone, vinyl records made a come back. There are no CD's for sale at concerts but there are special colored vinyl records. And as amazing as my Rega turntable sounded on the new system I couldn't help but regret that I'd sold my Linn...

i-HrfVLtp-X2.jpg

Sadly this is not the "exact" one - but it's the same one with a few upgrades. It needs a tune up but it sounds even more magical then I remember. When I got it I had Nadia sit and we did the old A/B routine. I played her favorite song on the Rega and then we swapped it for the Linn.

Nadia looked at me in shock after a few bars. Did you hear a difference Nadia? "The first time it sounded good - like we were in the audience at a show. But now it sounds like we are on the stage!"

That is a description that Rick would be proud of. Nothing about watts per channel but all about how the music sounds. This philosophy of function that I learned from Rick has stayed with me my whole life - something is better if it works better. My bikes, my photography and now, back to music. Full circle.

i-GqDLdVZ.jpg

The house feels different now. We spend way more time in the living room. When the kids are gone I'll turn out all the lights and sit in the dark and play records - exactly like I used to in college. It's more magical than I remember. All those records that I wanted to get rid of at one point? They are worth a fortune now!

I can't tell you how happy I am that I never got rid of them.

So next up we're going to give the LP-12 a tune up but first we need to make a jig because setting up an Linn LP12 is a black art and luckily I was trained by one of the best.

@sakurama Gegor - who makes your lift table? Are you happy with it? Is airover hydraulic, electric...?

Looking for something to raise and lower my assembly table which doubles as a table saw outfeed. Just can't take the bending over any more

Thanks
Ron

As Chris says it's a Handy. They're sort of the default lift in most shops. Expensive but I've had cheap lifts, like the Harbor Freight ones, and they just aren't stable. This is the Handy BOB 1500 Lift - which is now about twice what I paid for it 20 years ago but it has never missed a beat and is stable as hell. It could be smoother but I'm used to it.

It's probably way overkill for that use but it's been a great lift. Someday I'll make a pit and set it flush in the floor.

I was the neighborhood dump for old boat anchor 70's audio equipment and records for years, there's nothing better than an album when your wrenching in the shop. You have to listen to the whole side unless you want to crawl out and take your gloves off. Check out the Vevor Ultrasonic Record Cleaner, it's amazing how much goop came off some of my albums after I picked up one of these.

Your living room looks like a snapshot right out of the past. The albums, the Eames chair, the fans, it all works so well together. Well done.

I have always wanted one of those Eames chairs, but I can't afford one right now haha.

Thanks Dr.

The chair was a gift from Judiaann (and Ben) and it's special because I couldn't afford one either! It's the perfect chair for listening to music and spun the other way it's perfect for reading the paper in front of a fire. I consider myself very lucky.

I'm happy with how things are coming along in the house. I'm looking forward to doing the stairs this winter as that's a project that has been on the books for a while and all that wood has been stained and is ready to go.

I was looking at those already. I used to have a Nitty Gritty record cleaner but I sold it years ago and the way of ultrasonics make a lot of sense. I already have the ultrasonic cleaner so I ordered one of those motorized carriages from Alibaba and we'll see how that works when I finally get it.

I bought most all of my records used and some are dirty and some pristine but a good ultrasonic can really pull out a lot more music. Nadia loves the process of "resleeving" albums so hopefully I can get her into cleaning the records. In many ways the timing of this is perfect. She's very careful with them, knows how to handle them and also just loves the whole analog thing - the pops and ticks of old records, the big art work, the sleeves with the lyrics. All of it.

Of course I'm also a tape deck, Walkman and boombox lover and no stereo stack is complete without one. Unfortunately you need great eye sight and tiny JIS Screwdrivers to change belts which might take hours but it's worth the price if you like gadgets.

Gregor, when our children were in their early teens (1975) we instituted "Rebirth of Culture" night. One night a week there would be no television. They chose the night and were allowed to pursue anything they liked. Our daughter took up the guitar and our son chose to read books. His attention span at first wasn't great so I gave him The Collected Writings of Ambrose Beirse. One short story a night and pretty soon he was reading tomes. By the end of the second month of "Rebirth of Culture Night" the TV was rarely on and books became the norm. I feel blessed they grew up before computer games and the rectangular hole in the hand took over real life.

Hey Gregor,
Wonderful to see you blossom post separation...music with the kids...way to go!!!
Re your maple tree. There is a fellow on YouTube [and Instagram] from Portland by the name of Frank Howarth. He is a great woodworker who loves to mill fallen trees.

His contact details, cut and pasted from his YouTube site are:

Frank Makes LLC P.O. Box 25518 Portland, OR 97298.

I reckon he might be able to help you out. My guess is that you two would get on like a house on fire.

Cheers from downunder...
Jeff

Looks great. Vinyl rabbit hole...I live in Denmark - Struer. Home of B&O.

I ride gravel with B&O Creative Director Kresten, he mentioned a couple a years back that they revamped the Beogram 4000c. My neighbour went that way with the BeoVox 2500/5000 combined. Not cheap, but hey...rabbithole. It has great revealing warmth. Revealing in a Live sound.

Our kitchen needed some punch as my need for music is all day all year. Beolab 3 coupled with a Beolab 2. I will admit i am the anti-christ of music...im a Spotify streamer.'
20221129_105431.jpg

Newest addition is trying to match a Beolab 7-2 soundbar to my LG tv. THat soundbar might be the cheapest and best ever made. 750w icepower inside...150usd lol.

20221010_182900.jpg

Any specific projects in the shed?

oh, how is the 890 suspension setting in?

Gregor,

You musical taste mirror mine for all the (at the time) alternative music you listed. I've been exploring my stacks of records also. While I don't have the interest or ears (50% deaf), I have an interest in old Hi-Fi equipment as my dad was a classical music nut and always had the high end equipment everyone lusted for. While I can't appreciate the sound out of this equipment like I used to, I do have an eye for it to flip on ebay or locally. I do keep some of it whenever I want an upgrade. Years ago, bought some Allison Four Speakers from a moving sale for $35 and invested another $250 in restoring them. What a great sounding set of speakers! Even to my enhanced ears (hearing aids). Enjoy the music with the kids. What a priceless time you have with them. I listen mostly on my phone these days as I can stream straight to my hearing aids. Technology is great! Here's a few artists on my playlist (in no particular order): Dream Syndicate, Ziggy Marley (1st album), The Cure, Debbie Harry, DEVO, Echo & the Bunnymen, Frank Zappa, Human League, Joe Strummer and the Mescaleros, Killing Joke, Little Feat, Modern English, Morrissey, The Smiths, New Order, The Police, Polyrock, Siouxsie And The Banshees, UB40, Velvet Underground, XTC, AC/DC to name a few. One album I've been particularly enjoying revisiting is Debbie Harry's 1st solo effort called KooKoo (1981). KooKoo showcased the early fusion of funk, rock and dance music. If you can find this one, you will not regret listening....

As you have described already what you have done for your kids - and yourself - is really important. As an electrical engineer making a living in this digital world I think it is super important that we all learn to unplug. Especially young kids/adults. It is good for their mental health and for their creative minds to work with the things around them, in their world.

My dad has a pile of albums and a few turntables that he has been toting around. Maybe I'll encourage him to set the equipment back up :)

I'm going to look up Ambrose Beirse - Lucas reads constantly but mostly graphic novels. He's tried to read some bigger books but hasn't found the thing that clicks for him so collected short stories might be the trick. Thanks Bob!

You know Frank is a neighbor I'm pretty sure. I just don't know where exactly but I'm pretty sure he's on my side of town and you're right - he's a cool guy and I'm sure we'd get along. I just need to figure out how to actually meet him.

Regards from Denmark

I hate to say that $8000 suspension might actually be worth the money... but it's probably worth the money. I can honestly say it's the best suspension I've ever experienced including all the Ohlins I've ridden. I hope you come visit sometime and we can ride together.

As for other projects. I have a bunch of small ones right now. I need a stand for the turntable and possibly one for the hifi, I'm going to do more work on the mini framer and this year the 1 Show is moved up to it's old date which means I don't have the time to take on a big project so I'm either going to build up my Champion Penton or my Rickman Triumph. I think I'm going to do the Penton because I'm getting comfortable going faster on flat track and the Penton will let me bump into two new classes and also be large enough to race on bigger tracks outside in the summer.

Gregor,

KooKoo showcased the early fusion of funk, rock and dance music. If you can find this one, you will not regret listening....

I think I have all that you listed on vinyl except for KooKoo so I'll look for that on Discogs. When CD's came out people just gave records away and I'd take them. I was never a Ramones fan (respected them) but in going through my records I found a complete collection of 9 Ramones albums - all in all worth about $500. It's crazy to me how there's a market for this stuff now.

If you're not familiar there's a site called Discogs that is basically a catalog of all recorded music. You can input your records by scanning the bar code or inputting the name of the artist and from there you can see the average price of the record based on condition. It was more than a little shocking to me to find my original release copy of Nirvana is worth between $1000-2000 and honestly I was never a huge fan at the time. I had taken a photo for the newspaper the year before of a baby swimming so when I saw that record show up I bought it mostly for that. My Pixies records are all super pricey too. I've only input up to R right now but the current collection is "worth" between $15-40k which is bonkers. To think I was going to give it away at one point.

As you have described already what you have done for your kids - and yourself - is really important. As an electrical engineer making a living in this digital world I think it is super important that we all learn to unplug. Especially young kids/adults.

It's a funny thing screens. They are a part of our lives and truly indispensable and yet we are generally much better off when we're without them. When we used to go camping I would search cell phone maps to find places that would NOT have service to ensure that all present would be present.

With the kids I've found that when they get screen time they are much more short tempered and less helpful. When they lose it (for behavior or whatnot) they go through a very short anger stage and then become happy, friendly and helpful which really was the basis for me saying no screen at all during the school week. Once it's off the table they find a myriad of ways to play and be creative. It's a place that Judiaann and I differ on parenting but the kids know they get screen at her house but not at mine - and they just accept it.

I find that making the rule for them also forces me to stay off it which, just like the kids, gets me to work on other projects. It's amazing to me how you can pick up your phone and suddenly an hour has vanished and you have nothing to show for it.

Next up I'm making a service jig for the Linn.

Another fun rabbit hole, Gregor. That Rega deck is where I started years and years ago. Ended up with a VPI HW19 Mk 3 or so with a Moerch arm.

My current hifi thing is restoring old gear and sometimes building my own. Some recent projects include bringing some old TDA1541 CD players back to life, prototyping some Nelson Pass preamp designs, and I just finished a pair of small "Frugal-horn lite" full range horn-loaded speakers, with walnut veneer. Naim 250 clone project is on deck.

My large record collection came from a time when it was much easier and cheaper to acquire them. The serendipity of the search was always as much of an attraction as the thrift. You never knew what you'd find, and you'd find things you'd never know to look for. It would be impossible to replicate that experience today. Today nobody wants CDs, so...

I remember record stores used to have a turntable with headphones that you could listen to any (used) record on and so it was a fun way to find new music. An hour to kill between classes? Go to the record shop and just listen to stuff with cool covers and who knows what you'll find.

Random shuffles on Spotify or Apple sometimes come up with new things you've never heard of but they're never from way out in left field.

Probably the best, cheap deal in LPs today is classical repertoire. For folks who are curious, but don't know anything about "classical" music, there are still piles and piles of records out there to be had for free or essentially nothing. The box sets are particularly great because the records have been in a protective box for ages, they probably were rarely played if at all, and you get a pile of music in every box.

The investment is low. The opportunity to experience something new is high. If you don't like something, pass it on to a curious, adventurous friend, and try the next thing.

At some point yes the work and the performance and the recording matters. But you don't know to what to start hunting until you know what you want to hunt.

Still not an expert 30 years later. I have stumbled on some blow-the-top-off-my-head moments along the way.

This is very true. I'm a big classical music and opera buff (as well a rock blues and jazz of course) and the used LP/CD racks at thrift shops are full. I would suggest trying to avoid anything with "Greatest Hits of..." in the title with classical music, but if it names the group or orchestra is probably a decent bet.
I teach several music appreciation/history classes at my high school, and you would be amazed at the number of students who realize they actually really enjoy classical music or opera once they get a little experience with it. It is like red wine, coffee, or dark chocolate: at first taste you wonder why anyone would willingly consume that terrible stuff, but if you keep an open mind pretty soon you can't figure out how anyone could dislike it.

Happy to see things moving in the right direction for you Gregor!

Linn, Naim. Rega, Rotel, OH MY! I’ve been down that rabbit hole and still participate but not to the same depth. I too had a mentor of sorts in the audio game. My current setup is primarily a HT arrangement, significant evolution from my audio only days, with mix of older Rotel, Adcom, Mission, and newer Marantz and B&W. When living in England in the mid 90’s I went to several HiFi shoppes and auditioned all kinds of gear, most of it things that weren’t readily available stateside. Ruark, Quad, Meridian, Arcam, AudioLab, Royd and others.

If you have Fleetwood Mac's Rumors in the wax collection, that might be a good listen with the your rig. RIP Christine McVie.

By the way, I had an interesting and familiar email from Ducati today:


Watching it while knowing a bit about the background was really cool. Great stuff, as usual!

I was listening to Fleetwood Mac just last week. It really holds up and sad about McVie.

Because I can't leave well enough alone and because I wanted to do some updates to the Linn I needed to make a jig. Could you tune up the turntable without the jig?

i-Gmf6T9K-X2.jpg

Sure, but it would be not very optimal. You need access to the bottom.

i-bSskBVs-X2.jpg

The factory jig is a stand that clamps the turntable at the edges and has a pair of uprights that allow the jig to be laid on it's back to make working on the table easier vertically but the main job is to hold it level with the bottom open to adjust the suspension. The factory jigs come up for sale very infrequently and are expensive so building one seems like a good way to warm up in the shop.

i-JJkmS3K-X2.jpg

It starts with a sketch and some tube. I wasn't sure what size they used but I was pretty sure it was 1" or 25mm and I wanted to try smaller tube as I want to build a stand for the turntable too. I bought 3/4" and 1/2" and decided for the 3/4 for the jig.

i-43hLfrQ-X2.jpg

i-6ng6JhW-X2.jpg

First welds back are pretty good...

i-HzbkC3K-X2.jpg

i-bDzJBQZ-X2.jpg

The Linn jig uses philips screws to hold it together. I could have just welded the whole thing together but the original is screwed together to make it easier to ship and I choose to make mine break down to make it easier to store. I will use this only a few times but it's nice to have. So I break out my quick adjust knobs - a collection I have from trying to modify photo gear over the years.

i-CCXKqqm-X2.jpg

I could have bought inserts but it was Friday. Standard square nuts can fit the 3/4 tube perfectly but are standard and I like to keep projects metric or standard and if it's related to something European I'll try to be sure it's all metric. So had some 3/4 bar stock and drilled and tapped...

i-Fb96QwK-X2.jpg

...and then just fusion weld the seam with a fast pulse setting. I could dress the welds but I'm not going to bother. When I make the turntable stand - the one that will live in the living room - I'll dress those welds.

i-HnZkShd-X2.jpg

That is the bulk of the welding so I put it together and do a quick test fit.

i-hv8FhN5-X2.jpg

I've been measuring and re-measuring because the lip that the turntable rests on is only about 5mm on each side so this needs to be accurate but not too tight.

i-zMgZXv4-X2.jpg

So you can see it rests on that thin lip and the measurements are all good. Time for paint.

i-CgK25Qw-X2.jpg

The basic table is painted and the feet and cork from McMaster has arrived. I could have made feet but these have nice rubber bases and are M8 metric.

i-z3MNtwQ-X2.jpg

The thing I love about ordering from McMaster as compared to Amazon is that McMaster always surprises you with better quality than you expect. This cork has rubber in it making it a little sticky and less likely to slip. Nice.

i-drJtmbt-X2.jpg

I ordered 3/4" so it would match the tube but the edge clamps are narrower and need trimming.

i-XstLjn8-X2.jpg

So the base is done, corked and trimmed. I still need to make some clamping device. Linn uses these disks with wing nuts on the bottom that are... less than I'd expect from them. Since I'm all in at this point I'll make something better.

I'll save that for the next part.

Gregor,
Nice work as always. Those chairs in the 1st image look very Heywood Wakefieldish?

That's not me. It's a photo I found of one of the more precarious ways that people try to support the turntable. Gives me the creeps seeing that.

i-XZ3njjj-X2.jpg

With the turntable in place I dig through the scrap and find some 1" angle iron that will make a good clamp. The angle to where the bolt will be has a bit of a gap and my first thought was to just weld the threaded rod onto the angle but...

i-DbzkkFx-X2.jpg

...I decide to make a stand off and then use an insert so it's not fiddly but they need the right amount of offset so I'll mill a flat onto them. This way they'll be aligned.

i-vch5sq3-X2.jpg

i-9bkFtD3-X2.jpg

I had a friend visiting so she was able to snap some photos while I worked so you can see both my scratched up hands.

i-bKTSqKq-X2.jpg

I was thinking of trying to weld all this with bronze but decided to just use steel filler to make it easy.

i-CqG4R3k.jpg

So here are the brackets. I milled and ground them flat so the pressure would be even.

I ended up using a threaded insert on the base as I didn't drill the holes through for the clamp because I just didn't like that idea. Felt like it should be neater and cleaner.

i-H7M2S8V.jpg

And since I was using stainless all thread I decided to make some stainless knobs. Knurling stainless is pretty hard as you need a crazy amount of pressure but I seem to get lucky with a slow speed and fast feed and just crush it until it repeats and you get a clean knurl.

i-C2vHtTg.jpg

The knurls aren't perfect diamonds but they're close enough and have a LOT of grip. I drilled and tapped them and then welded the threaded rods with the intent of machining that clean again. Chamfers on knurls keep things neat.

i-vmNjhcg.jpg

So I'm very happy with the clamps. I think since this blog started you've seen me evolve over the last 10 years to be a much better machinist and fabricator. It's been interesting to see this evolution unfold and every once in a while I have to take a moment and appreciate that I've improved. All the fits are perfect, the bolts line up, the holes line up and the table is square and straight. I wasn't being super careful but my "feel" is better.

i-CL2kkdp.jpg

This is my new favorite paint. I love a good textured surface or paint. I used to love the wrinkle paint that was used in the 40's and the knockdown texture we did in the upstairs rooms - it covers mistakes but also evens things out. Texture is more interesting. More technical.

i-Jr3hFPg.jpg

And that is that. Next thing to do is to get the turntable mounted and taken apart and do the updates. I think before I do that I might make the stand for the turntable - the one that it will live on permanently. The world of hifi is goofy and mercurial and I feel like it changes all the time much like health advice. When I was involved you wanted to create very rigid structures to allow the sound to be accurate and now there's a trend to decouple. Decoupling at the source makes sense but at the speakers doesn't.

I'm going to build a sturdy base or platform and the turntable has rubber feet so who knows. I'll listen to the differences and see what I think. For now it sounds amazing so hopefully the updates will just be more of the same.

i-Smr5jpJ.jpg

The sketch at the beginning was very basic and in pencil. As I build, especially something like this where I'm not sure exactly what all the solutions are going to be, I make changes in the drawing. As I weld and lock things in I go back to the sketch and start playing with it, locking in the sketch with pen while waiting for paint to dry. I just love drawing so it's another way for me to relax, clear my head and think.

And that wraps up that project. I have a bunch of small things I want to knock out and I'm not sure what I'm going to do next. I may wait to do the turntable updates until I've built the stand so I can hear the differences accurately but right now I'm happy to have the shop time. Whatever it is.

Gregor, the above statement hit me like a brick as I completely agree for myself as well. I'm not one to dwell in the past but every once in a while I will look back at work I did 10, 20 or even 30+ years ago and am amazed at how far I've come. Unfortunately, I don't think I will ever be as good as I want to be but sometimes we are our worst critics and I have to keep telling myself that it is a journey and as long as I am improving upon my skillset it is time well spent.

Stand looks great by the way. :thumbup:

Great project.

The fine textured looks nice. I keep looking for a good way to replicate the hammered texture paint of quality tooling. Also feel texture makes things look better.

Gregor I really appreciate your attention to detail in every aspect of your life. Thank you for sharing, it’s an inspiration to those of us that seem to have more irons in the fire than we can manage. Like you I've loved vinyl since I was a teenager back in the 70’s. My B&O system, finally after nearly 50 years of use died a painful death, first the tape deck, then the turntable an untimely the amp. I couldn’t find anyone to repair it so it was donated. My old tube amp that to me produced warmest pure listening music didn’t survive my latest cross country move and was deemed a lost cause as well by my trusted amp shop that has serviced this one for many years. The new digital stuff just doesn’t “feel” as comforting.

Portland - the cool one.
The hifi shop I worked at, Audio Alternative, in Fort Collins, CO, did mostly pretty high end British hifi - specifically Linn and Naim. Those brands are either adored or reviled in today's world because they very much had a cult like following. As I mentioned the two things that drew me to the shop and the brands they handled - music and Rick.

It's hard to believe now but a lot of stereo shops of the time were only concerned with how many watts per channel something made and they would play "test" records - not music - from a laughably tiny collection of bad records. So Rick, passionate about music and always willing to listen and try things, made a lot of sense. Plus his collection of 10,000 records spoke to his passion.

The older system I ended up with was a pretty great set up albeit 10 years old at the time (40 years old now) but the system that I remember being the most amazing was one built up of Naim gear that used two amps and an active crossover.

Turns out Brexit is good for something. Back in Sept when the GBP was basically even to the dollar I found a couple of very good deals on some older Naim gear and snatched it up thinking I would either resell it or build that system. The problem (or feature) with British Naim gear is that it's wired for 240v so most people in the US don't consider buying in England so the prices are lower.

But I knew a little secret from my days at the shop.


i-XQxnKS6-X2.jpg

With the feet off and a five screws the amp comes apart easily.

i-jNZ4MWP-X2.jpg

And this is why I love Naim so much. Inside, where no one sees, they dress the loom to make it beautiful. It's probably where I fell in love with the idea of making details perfect that no one would ever see. To me this was an easter egg before there were computer easter eggs.

i-dJKWSjX-X2.jpg

Since Naim wasn't going to build for just the European market they built their transformers to use 240v or 120v depending on whether they were wired in series or parallel. I had to ask because I'd forgotten exactly how but inside this neat loom is a secret.

i-XL66Xmh-X2.jpg

The wires inside this bit of shrink wrap are soldered together for 240v operation...

i-6pSJ2BT-X2.jpg

...desolder them...

i-HRk6CcF-X2.jpg

...and solder them separately to the other leads from the transformer and you've converted a 240v amp to 120v.

i-HKTPdG5-X2.jpg

I didn't have white zip ties. Or enough black ones to replace all the rest. I hope you aren't disappointed. I know you are. That's okay.

i-MtSXJ7j-X2.jpg

The last detail is you need to change the fuse from 4amps to 8amps (which is even explained on the back of the amp)

i-k8tFWHp-X2.jpg

Same goes for this Hicap but the wires are a little different. Same beautiful attention to detail inside however.

i-q6RbLb6-X2.jpg

It's interesting that they actually go out of their way to bury the spliced wires inside the middle of the loom so that they are completely hidden.

i-BQT6gB4-X2.jpg
i-cKhVSW2-X2.jpg

I was warned that you need to be fast with the soldering iron because, evidently, the switches are unobtanium now with this gear nearing 20 years old. Much like my motorcycles I like having the very best - 20 to 50 years after the fact when I can afford it.

i-wJqXR8p-X2.jpg

Again with the black zip ties.

Naim will do this mod for you but at a cost of $295 per unit.

The temporary placement of the gear on the credenza will need to be resolved because it was never meant for that sort of weight and it's sagging. So I'm going to build something for the gear but I want it to be interesting and functional and I haven't resolved that yet.

But next up I'm going to build a stand for the turntable. Simple, light and delicate.

Twenty-two years ago I turned the TV off, besides occasional movie maybe once a month if even then. Wouldn't believe the things one can learn or do in the time the average American time spends indoors watching TV.

Just fantastic. I've enjoyed the ride that you have been so willing to share with us here. From pizza to your motorcycle adventures to this now...wow. Thanks!

Cable lacing, a very classy alternative to zip ties. If you're going down the perfectionist rat hole it's one more thing to add to the arsenal. The vacuum tube power supply on my Monarch 10 ee had this done and it was very cool looking. Sadly I finally had to give in on the vacuum tubes and convert to a proper inverter vector drive. I am going to go back and replace the cables ties I used with lacing, just because.

So the credenza...

It wasn't a particularly nice piece of furniture when I bought it years ago but I'd still like to keep it. And fix it.

i-tSnRVwG-X2.jpg

So it's sagging about 3-5mm in the middle. It's held hifi gear for too long and...

i-fV9DBXB-X2.jpg

...putting a jack under it to see if the stress was set didn't make much difference. Are there options to unwarp this?

I thought perhaps I could empty it out and make a couple of 2x4's that have a 1/2" block in the middle and then squeeze it gently from the ends forcing the middle up and then let it sit. Not sure for how long or if that would undue years of abuse. Also, Snail Mail is some really nice emo, grunge, alternative - there's too many categories of music.

i-Jwn6xZ4-X2.jpg

So I looked at 3/4" 5/8" and 1/2" square tube when I went to the metal supplier. 3/4" seemed nice but just a bit too chunky and 1/2" was very tempting but they didn't have much and it was worryingly thin. Not in a strength way but in a visual way. So 5/8" or just about 16mm was the sweet spot.

i-F4wzP7v-X2.jpg

I ran an end mill over them as a group to get them all the same 444mm which is the exact size of the OD of the LP-12. My plan is to make a perfect square of the width of the turntable and match the depth as well so it's a perfect match. If you're going to build a custom table you might as well make it custom.

i-54kttbC-X2.jpg

Instead of drilling these individually like I did with the work jig I drilled the bar stock first on the lathe and then cut them out. I decided to not tap them until it was built so welding wouldn't put stress into them and I'd have to chase them anyway. So these are the uprights of the square tapped into the ends and fusion welded.

i-C5JRP8P-X2.jpg

I subtracted 16mm x 2 from 444 and cut the cross pieces. It's funny that when I started welding my biggest challenge was to not burn the **** out of the material. I had a led foot on the pedal. Now my challenge is to equally distribute the heat to control the warping.

i-pNPFPVW-X2.jpg

Measuring diagonals is how you can tell if your square is square. This is less than 1mm out right now - yay!

i-2WpwT92-X2.jpg

Of course as I stitch and flip and balance heat I get a warp in the third dimension. Clamps and vise-grips and trying to weld where the heat will contract it back to flat seemed to do the trick. The other part of that is trusting your heat will balance the equation.

i-BV2wSWJ-X2.jpg

Because I want this to look clean I'm grinding the welds and also I'm grinding them because I need to now weld the vertical parts of the box.

i-rXtqBnr-X2.jpg

These little magnets have paid for themselves many times over. I prefer the ones you can turn on and off (background) but these are narrower and work better for this tube. Small tacks in the middle of the tube to keep it from pulling.

i-FsrgqvW-X2.jpg

A box seems simple until you try to weld one. Then you realize how many ways it can go pear shaped instead of square shaped.

i-FK4XsfP-X2.jpg

Now all the "depth" sections are tacked into the front (or back) of the box.

i-Wfzx8kx-X2.jpg

For the most part it lined up. One arm needed a small amount of persuasion to meet up but since it's all tacks at this point that wasn't too hard. From here I am measuring the other diagonals to make sure I don't end up with a parallelogram table. I had to do a small squeeze with a clamp to bring in one side about 2-3mm but for the most part I was pretty good. I would weld a seam, spin the table and weld the opposite one and then flip it and weld the other side and just kept repeating that until...

i-Z5TbCmf-X2.jpg

I got to the inside corners which I left to last thinking that they'd pull but if the rest was locked in it would be mitigated. That seems to have worked.

i-hJjh4Xh-X2.jpg

I tried to make sure my welds were proud (I wasn't...) so I'd have material to grind flat.

i-5p3p8DZ-X2.jpg

Then I'd use my favorite grinder - my Milwaukee cordless - and an 80 grit flap wheel to flatten the welds.

i-XHgHTtn-X2.jpg

Despite best efforts there were some small spots that were missed and I went back over them (with a better point on my tungsten I swear to you) and put a bit more filler in them.

i-HrQBXrV-X2.jpg

Then I broke out the Festool Orbital and dressed the corners to match the rounded edges of the tubing. The goal is to make the box look like a factory offering but more burly. The inside fillet tig welds are something you probably wouldn't see but I tried to make them small enough to match the curve of the tubing but in reverse.

The last step was to tap the holes to M8...

i-89tx4XN-X2.jpg

...and wouldn't you know it! My favorite drill/tap broke on the very last one. I wasn't using tapping fluid (after the first hole) as I didn't want to get the tubes greasy before paint. Ah, corner cutting, it always has a cost. I got very lucky and was able to back this out with vise grips.

Not sure about what sort of finish - I might leave it semi gloss if it looks nice.

But we interrupt this project to get a christmas tree...

On the credenza; I can't tell from the photo if there is a vertical divider or support behind those sliding doors. That is an awfully long span without support for the top; perhaps one needs to be added? Or is there a support and the sag is on both the top and the bottom? In that case assuming you can get the warp out of the plywood could a center leg under it be added, with an adjustable foot to account for floor variance?

There's an internal divider that spans the interior width/height but no central foot to support the load. I think adding a central foot would make sense. That was why I wanted to try the jack - to see if the sag was just deflection that could be eliminated by just giving it some support. Unfortunately the jack lifted the whole thing, sagging middle and all.

If that can be put into the wood with pressure over time it stands to reason that it could be reversed but how long and what sort of pressure would work before it breaks? Would moisture (humidity?) work? Just pressure? For a week? I just don't know. And I think just moving the hifi gear out of it is the best solution for now.

Personally I'd be leery of moisture; veneer delamination would be a downer. If it were me, I'd flip it upside down with a 2x4 across each end to raise it off the floor and then weight the bottom (which would of course be on top at this point) with some heavy stuff and leave it a week or possibly two. Ideally I'd like to see it relax so that it "sagged" the opposite it does now (hence my suggestion to raise it on some 2x4s) and then add the adjustable foot.

Don't use moisture, I'd even be leery of using heat on an existing finished surface. To stiffen the top I think you'll need to either stiffen with steel or cut a dado on the inside and reinforce with carbon. I have some extra carbon bars for building guitar necks if you'd like to experiment.

The wood is too thin, I don't think you'll be able to train it into any new form that'll hold flat.
