A_Pmech, I might have passed over it, but what kind of lathes do you have? And what's the size of them?
Thanks,
Chris

Hi Red,
I measure pitch diameter over wires or with a thread micrometer. While it takes a steady hand and careful manipulation, either method is generally accurate to about +- .0005" PD, although better results can be achieved with care. That's close enough to hit the middle of the tolerance range for a class 2 thread.

Hi Chris,
At the moment I only have one, a 14" 1970 American Pacemaker. One of the last built. Eventually, I want to augment it with a Monarch EE and a larger Pacemaker, something around 36" swing.

Is that a Heckert Horizontal in the background?
You're welcome. They're out there, you just have to keep your eyes peeled.

A universal Heckert horizontal actually!
Better yet, they had a Kearney & Trecker 420 TwinFeed vertical. Want!

Nice, we have a couple of heckert universal mills in our blocking area at work, both vertical and horizontals. We also have a nice little Varnamo vertical and an OLD tired, worn out Kempsmith mastermill horizontal that is soooooo sloppy we can't block with it anymore. I can grab the table and get the ends to move about 3/8" if I give it a good shake lol.
I've been in an organizing mood lately and this project is part of organizing the shop. I have numerous Aloris CA toolholders stuffed in work bench drawers and I have plans to purchase and make many more. Each one weighs about 10 lbs with a tool installed in it, which means the work bench drawers aren't too happy with me. So, I came up with a solution. I call this the "Aloris Tree". It will hold 56 toolholders when complete and is configurable for any size holder from AXA to DA:
It's almost ready for paint and final assembly.

Hey A_PMech... I got a dumb noob-type question. What did you use to lay out all the angles in a consistent manner on your tool holder...holder?
Hi Fergus,
I used an adjustable angle plate and welded every "branch" in the same manner so they would all distort in the same direction. As expected, I ran into some distortion of the column when I welded all the branches on the tree:
Nothing a little heat can't fix though.
For anyone who eants to learn about heat straightening, the best book on the subject is "Heat-Straightening Repairs of Damaged Steel Bridges, A Technical Guide and Manual of Practice" Published by the U.S. Dept. of Transportation and the Federal Highway Administration. Report No. FHWA-IF-99-004, October 1998
It curved in two axes about an inch over 6'. I expected that because of the way I welded the branches onto the tree. By welding all the branches on one side of the tree at a time I induced tension in the two sides of the weldment.
The "better" way would have been to weld a branch, then rotate it 180 degrees and weld a branch, then rotate it 90 degrees and weld a branch, then rotate it 180 degrees and weld a branch. That would have eliminated most of the "pull" in the column but would require a welding positioner to flip the column each time while everything was still hot. I have the parts for a nice one, but haven't built yet.
There's a saying that goes something like "If you wait until you're fully prepared to do something, you'll never do it because you'll never be fully prepared." That saying certainly applies in this case. Last week I decided to begin the project that's been on my grating on my mind for years: The Paulding Racer.
What is the Paulding Racer? Well, I asked myself that several years ago. The questions I asked were "What if I could do anything within the laws of physics without the hindrance of racing class rules and state vehicle safety rules?" and "If I could, what would it be?"
The two-stroke road racer has seen very little development since the mid 1980's due mostly to homologation rules and state emissions laws changing the bikes fielded on the track. Yet, there are a few things left untried and modern computer technology has made those things possible. My vision is an advancement of the two-stroke road racing motorcycle, perhaps bringing it back to the podium if anybody dares race against it.
It's a project of immense proportions and unknown development brick walls. My favorite kind!

Awesome idea man. I feel as though I'm watching the beginning of something grand. Like a modern day Britten. Don't feel uncomfortable with that comparison...if you want to do something badly enough, you will. You definitely have the odds stacked in your favor as far as your abilities and capabilities run. And you've got quite a shop to work out of. I'm glad to see you put it all to great use.
Oh...I love the sound and smell of two strokes. I often look up RD 500s , TZs, etc on Youtube just to hear em run. So I'm slightly biased. I've just subscribed to your blog.

Great to see a new post from you! I assume you used something besides OA to actually weld that tool holder holder. It's still cool to see others using OA, even for heat straightening. That is actually why I picked OA as my first welding process in The Aerodrome Studio...it is so versatile: brazing, welding, heating, bending, cutting (with the right torch). With the small torches I am using, it will take nearly-forever to go through the larger gas bottles I have.
I was actually AO welding for practice on 'coupons' of scrap steel today. I've been using a Victor 100 torch for now, but I will start moving toward thinner material with my Meco Midget torch, until I get to welding aluminum sheet metal, which is my eventual goal. I think I've become pretty consistent in technique, now I just need to play with different tips and thicknesses of steel.
Anyway, cool design for a tool holder holder. It is always great to see what you are working on in your shop. Looking forward to seeing it with tool holders on it.

As a kart racer of nearly 40 years, I have a liking for 2-stroke motors, especially water cooled. Subscribed.
BTW, what can't you do in that shop?

Hi Fergus,
I think Britten and I have similar modes of thinking and share a lot of experiences in common. I'm always impressed with how much he did with the little he had available to him. His achievements are something to aspire to.
This engine will probably not sound much like a loop-scavenged 2-stroke. It will probably sound more like a modern 4-stroke but with a much louder and higher pitched exhaust note due to the slightly early exhaust valve timing.
I figure the engine will have a redline in the neighborhood of 10,000 to 15,000 RPM, which means it will sound like a 4-cylinder 4-stroke operating at 20,000 to 30,000 RPM. All in all, it will probably sound like a very big and very angry RD500. We'll see...
As the engine will use full pressure lubrication and journal bearings there will be no need to inject oil with the fuel or use pre-mix. The smell of half-burned castor oil will be missing from the equation, but I think it will have other redeeming qualities.
The RD-500 was actually my "quest bike" before I decided even it wouldn't satisfy my need to build something.

Kev,
The tool tree is welded with the SMAW process using 6013 electrodes.
OA is a very versatile process and has so many applications besides just welding. Heating, flame heat treating and cutting are all within it's capabilities. No shop is complete without an OFW rig.
It sounds like you're progressing well. "Modern Welding" by Turnquist has one of the best sections on OFW welding and cutting I've seen in any welding textbook. If you don't already have a copy it's worth the few bucks to buy a used one from Amazon.
I'm ordering the HDPE for the tool holder blocks today.

Zeke,
So do I. It's time to take the 2-stroke to it's logical conclusion.
Well, I haven't found anything I can't tackle yet.

Oh...forgot to mention that I've owned an RD 500 before. It was definitely the 'crotch rocket' of it's day.
My little pipe dream is to build a radial-engined car. I was thinking about using the heads from modern V-Twin motorcycles and arranging 3 to 5 of those in a circle and figuring out a central crank shaft box to bolt on those air cooled cylinders. Of course, if you are going to do something like that, you have to build the vehicle so the engine is visible and a central part of the design.

I am working on my own 2-stroke project I am mating a arctic cat 440 to a suzuki t250 engine 
This is true!
Thank you.

It's going to be a loooooong project, but I'm looking forward to it!
It sounds like you'll have a fun ride when you're done.
Being somewhat of a 2-stroke nut, I can't wait to hear it (someday)! Good luck with your endeavour. Sound interesting, for sure, and it should be fun to see where you take this project.
I'm back to work on the surface grinder again! It's about time...

Just caught your thread for the first time...I must say ( as a machinist/welder ) I'm mighty impressed with your "garage" shop...My only question is, "Where in the world did you come up with all the time & money...? Let alone some very good connections..." lol
Keep up the good work...Kevin

wow!! how did i miss this garage bulid ? I plan on doing something like this. a wood & metal shop to rebulid and restore old machines, appliances, furniture,lawn epuipment , cars, what ever the harts desire ect. so with that being said what you do differant?

I thought about your question in regard to how I find time. It's really all about using the time I have. Maybe this post on my blog will shed some light on that:
DETONATION AT THE LAUNDROMAT
Hi Miatakid,
Well, the short answer is: Nothing!
The slightly longer answer is: It isn't done yet!
If I could have one thing it would be a fully powered overhead crane. When I build my high bay that will be one of the main priorities.

Re: My Garage Shop
Walking in your footsteps AP! I took part in trade for renovating an old building a mid 70's Champion two stage compressor a few years back that supplies my entire shop with all the air I can use at one time... and the best part is, it's not in the shop at all but behind it in an old Semi trailer I use to keep lawn and garden stuff in. Plumbed from gable end to gable end with 1" black iron and a 'T' at every 10' section... plenty of service drops!
Fantastic shop btw!
Another new addition to the shop!
This time, it's a Quincy 5120 air compressor. This unit will augment my existing 3hp IR compressor. The pump is 4 cylinders, 25 HP and 95 CFM. Hopefully my last air compressor! These machines are built like a tank, as it stands it weighs right around 1,600lbs. The pumps are pressure lubricated, completely rebuildable and are designed for 50,000 hours of operation between rebuilds.
More info and a video in my post in the compressor thread here:

While not technically "big iron" I thought you might enjoy seeing a working 1/14th Bridgeport!
