let's see your craftsman block grinders

[nine4gmc]

I found it! Stick to grinders and vises. Stay away from beverage machines.

[emoji38] you put in work for that one! [emoji481]

That ^^^ is funny.

Something else that is funny, a significant other that knows what you are up to.

I'm retired for almost 2 years now, and I'm enjoying not having to fight traffic.

So I called my wife around noon today, to say I was about 10 mins. away from where she works.

Now, she works about 60 mins. from the house through traffic.

She asked: "NOW what grinder did you find?"

We met for lunch and I confessed to buying ^^^^ a 3/4-HP HD split-phase on a CM stand.

She's such a sweetheart, she paid for lunch, even after I told her I gave the guy an extra $10, just because I felt his ask was too low.

Once I get it out of the truck (it's raining), I post up better pictures.

Thanks for looking.
3/4-HP HD split-phase on a stand, for $50.

Nice find! Is that a 7"er?

 

[drivesitfar]

Doc: another good find and a great story. nice gesture to the guy asking too little for it. WELL DONE SIR

That's a coincidence!
I did the same when I bought my half horse block sitting on the original cast iron stand rust free with original paint.
The old guy was only asking $50
I gave him all my cash which at the time was $60.

Long story(documented in the quarter million member thread) but luckily this was a gag gift reminder from Richard Cranium. [emoji38]

[badguy]

I picked up this guy recently from someone on craigslist.



I cleaned it up and mounted it on the stand I had originally made for my vise, which works much better for this grinder.



Thanks to all you guys sharing the info on these machines. Luckily I haven't had to fix anything yet, but it's good to know where to turn if I need help!

 

[drivesitfar]

BG: nicely done. i like the grinder stand too. any chance you took a few pictures of the grinder stand that you can post in the grinder and vise stand thread over in Fabrication section? a lot of guys have and would like to build that stand and if a few guys would show us how they built it i'm guessing more of us would own one.

i can usually find old commercial truck rims cheap or free if i look a little for them and a piece of steel pipe and plate can be found or bought and you have a stand.

nice job on the clean up too and your 1/3 HP block is ready to work. does it run nice and smooth or do you need to change out the bearings?

Yeah, I like to get a Block at a good price, just as much as the next guy; but, I want to leave feeling it was a fair horse trade.

 

[drivesitfar]

Doc: i only welcome new members and give them a quick post in case you are out chasing down another block. you are our KING or HEAD PUMBA and we all just try to find a way to keep pulling information about these old blocks out of your brain as we all add a little or all of what we know.

in case any of you want to go to Doc's thread where he lists the various blocks with sizes and HP and stats you might also notice he's OWNED all of those or still does.

speaking of which i think i should be looking harder for that 3/4 or 1HP round top block that i've been on top of the list for over a year now or maybe longer.

As i mentioned a couple times i don't NEED another grinder or Block, but when has NEED ever been a reason to buy another great old tool.

 

[torqueman2002]

Hahaha --- ".... but when has NEED ever been a reason to buy another great old tool." I couldn't agree more!

Thanks for the kind words drives.

Also, I just discovered a good buy for the Mid-West members. Link is below.

1/2-HP m-397.19340 with stand $100.

The listing is by a pawn shop, but I have had good luck with negotiating lower prices with pawn shops before. You may want to wait until the ad is a bit older.

Thanks Drives, everything runs smoothly - all I need to do is true up the wheels and I should be good to go.

I'll throw some shots and a quick description over in the stand thread. It ain't pretty but it works.

Thanks Doc! It's the least I could do, especially compared to all you do for everyone!

ALL: with the posts you guys (and gals) make on this thread make it maybe my FAVORITE thread on GJ and i want to send a special thanks to all of you. attitude, information and friendly are all impressive.

I was poking around the VM web site and found a Craftsman Tool catalog I haven't seen before.

1976/1977 Sears Craftsman Power and Hand Tool Catalog Craftsman 50th Anniversary

To keep this post, Block grinder related, I copied this page.

The full catalog is available for free download.

[Outlawmws]

Interesting that they would list 76 as the 50th, since I have a 1931 catalog with Craftsman tools in it...

33 was the first year they put Craftsman (and Companion) on the cover.

35 headlined Craftsman

36 - 39 went back to both Craftsman (and Companion)

And 1940 was when they again headlined Craftsman

But thanks for the link TM!

 

[JZiggy]

Doc -- so glad you posted that. I have that tubular stand shown in the top right corner! It came as part of a CL deal and I stashed it and never thought anything of it.

Was the "Sears Best" sticker for multiple years or did it originate in this "50th anniversary" year?

 

[Outlawmws]

I've seen that in the '73 catalog also so multiple years.

Yeah, been there, done that and spent the weekend about 20 years ago. Wrong place & time but it's just another costly life lesson if you learn from it I guess.

Sorry if I keep rehashing the same info that might be here. Do we have documented what grit stones came on each size, whether wheel size, HP was a factor?

Making an assumption since Sears still sells 36, 60, and 100 these would have come either 36/60 or 60/100 but 36/60 seems more likely. Then again this was 40 years ago at least so could have no bearing anymore.

I have a few stones that have no more label. Of the 6 stones, 2 were still good enough to keep. As a result I have a 6" 60 grit and 36 grit 8" (new Norton) and whatever the 1HP 8" would have had on the right side (I assume this is the original stone some of the label is there but I don't recall seeing the grit)

So my main question is, if I was to go with 4 total stones coarse med medfine fine should I be going 36 60 100 120? or is there not enough difference from 100 to 120 that I should look for something finer?

Most of these are made in china from the looks on websites. I'm not looking to spend hundreds on grinding wheels the new 8" I got is a Norton the other two being the originals. Are these two good choices?

Finally. The grinding face of the 6"x60 grit wheel looks really shiny. It's smooth. I haven't yet taken a dresser to it, it does ring but I didn't know if that would be a dangerous thing to do so I'm asking first. I have no idea what it could be impregnated with to smooth out the face but it's about the smoothest 60 grit I have ever seen.

Still working on getting pics sorry again for the delay.

Oh no! A 3/4hp is actually a 1.1hp on the split-phase? What is it on a cap start? What is it on a 1hp? How about a 1/2hp? What about flat-tops vs round-tops? It never ends!

Edit: I read a deeper. There is a 2/3Hp that develops 7/10ths hp? And the 3/4hp develops 3/4hp? Typos, marketing, or a combination of both.

I'm confused now with the wheel sizes. I've never seen a 6-inch block with the die-cast "Princess Leia buns" centers---I thought they were always 7-inch or 8-inch grinders. Yet no mention at all in the catalog of a 7-inch version. Are there 6-inch, 7-inch, and 8-inch die-cast chute guards?

Maybe. And this is just a thought.

buy a new chinese bench grinder rated at 1/2 HP. Guarantee that's based on peak amp draw. Now I'm not saying that this is right but if we apply the same logic, where it's used as a selling point, it's not much of a leap to think Sears could make a good machine that generates running amps to equate to 2/3 HP but its peak amperage could generate 7/10 HP (I mean 0.67 to 0.70 is not a leap really) or the 3/4 generating 1HP or more by the same logic.

The main difference is the typical 1/2 HP chinese grinder probably has typical 1/10 HP at 4 amps while typical block 1/2 HP probably has typical 1/2 HP at 2.5-3 amps.

Is there a possibility the commercial 1/2 HP with the chutes and the Leia buns were sold as 6" although they were capable of 7" discs? I have no idea. I am trying to read this whole thread and learn more but there is quite a lot of it.

OK so maybe this was a rant. But it felt good. I now own zero ****** chinese grinders. Probably keeping the one buffer since it doesn't **** though it's no Baldor.

Canadians Looking For Rubber Feet . . .

Why would we want rubber feet? For our grinders of course!

Where to find these often MIA items in Canada was an interesting quest.

Lowes? Nope. Not in their master catalogue, not available in Canada.

The Mysterious Lau Vibro Pad 38-2209-01? Nope. I contacted Lau in the US and they gave me the name of their Canadian distributor, Emerson. Contacted Emerson, they only sell to distributors. Contacted a few of my local industrial suppliers. Nope. They can order, but you have to buy in bulk, enough to rebuild more grinders than there are in the whole of Canada.

Then a previous post (read up many pages) where a GJ member found some at Graingers. Fantastic! Went to our version of Graingers, Acklands-Grainger, looked them up and Lo and Behold!

Called my local Acklands-Grainger, and found they are not stocked in Canada, have to order from Grainger US (oh no, heart sinking), but NOT a special order. Fantastic!

Ordered two packs, person said 8-10 days, they arrived 3 days later at my local A-G, who then called me for pick up. Not cheap, CA$16 for six. But if you are looking to finalize a grinder for that Special Someone, well what's a couple of bucks per foot (so to speak).

They are a perfect fit. Six per pack. The two on top are from the second pack to show a profile.

So there we go!

About a week ago, a member over at OWWM emailed me about an issue he's having with his 1hp #397.19360 block. He thinks that a PO wired the capacitor wrong and needed pictures of a working one. I finally made the time to open mine up and take pics. I though that I'd post them here as well, since I have it open anyway.

Given how filthy the grinder was, and how much fluffy grit was under the base on the stand, I thought the inside would be a mess. I was surprised to find a nearly pristine interior. Just a little dust. Everything still looks nearly new inside. It kind of makes me wonder why I'm having starting issues with mine.

I think I need to replace the starter relay, or the capacitor. But not being good with a multi-meter, how can I easily tell which one needs to be replaced ?

Right now, when I turn it on I get a loud awful noise until the wheels get to speed. It starts out slow and takes it's time to get going. If I help it by spinning the wheels it gets there faster. After it's up to speed, there are no issues and it runs fine with no noises.


Pics of the wiring wire diagram and inside wires.

 

[cheechi]

not an expert but that sounds like it could also be a bearing issue.

 

[drivesitfar]

Jake: i'd agree that bearings might be the cause, but i don't own one of those big blocks so maybe Doc or EX or McB has your answer.

Isaiah: for a new member that was a great post. Really happy to have a guy like you on the forum and hope you stick around. i bet the guys in Canada might find that information useful too if they can ever get their hands on these old blocks which seem to be really rare up there.

thanks

Jake and Drives,

I'll have to defer to the good doctor. The 397.19360 doesn't look like my 397.19591 or 397.19670:

View media item 44389
By the way, I would guess capacitor and wouldn't think bearings since the noise goes away. I agree, a multi-meter is the place to start. Again, Doc to the rescue!

Canadians Looking For Rubber Feet . . .

So there we go!

Matthew A.

Shoot! There goes my retirement plan of smuggling rubber grinder feet across the lake for extra cash.

 

[torqueman2002]

I would guess cap as well. Those grinders are old, and caps don't last forever.

I'd recommend replacing the cap. It's the cheapest, easiest to replace, and most likely the problem.

Be sure to discharge the cap.

The relay (potential) is very reliable and it is not the same design as an automotive relay we are familiar with.

The operation of the potential relay is based on the increase in back-electro-motive force (back-EMF) or a bucking voltage that is generated across the start winding as the motor increases in speed. The large metal mass of the motor’s rotor turning at high speeds with motor windings in close proximity has a voltage-generating effect.

Found this grinder today at a garage sale.
Looks rough but runs like brand new.
Bought it and a 9" sander.
$15 for the pair.

Any idea on its age?

 

[drivesitfar]

RP: you did good with that purchase. WELL DONE.

not only is it a 3/4 HP which isn't common, but you found it with the huge water tray/stand combo.

nicely done

 

[Reversepolarity]

It is missing one rubber foot.
Other than that runs and sounds new.
Any way to tell the age?
