let's see your craftsman block grinders

Anyone around Temple, TX want to pick me up my first block head? If my daughter's first birthday wasn't this weekend, I would be all over it.

Nice grinder (missing eye shields & never had the cooling tray, but they are available) for a nice low price. Too bad we don't have a set up like OWWM where people will transport machines x-country for one another.

Do you know the model no? I'm thinking 1/4 or 1/3 HP with 6" wheels, but maybe 1/2 HP.

Oh, BTW - the grinders are the Blocks; it the crazy hoarders that are the Blockheads!

Here's a picture, should the CL go away.

-Brent- · Apr 8, 2014

Torque, is it safe to say you're the biggest blockhead around? Or, is there a "collector" that surpasses you?

It also looks like one of the tool rests are missing as well. My brother lives an hour away and he reluctantly said he would get it if I can find anyone closer. Waiting on a response from the seller to find out model number and details about it.

Does any one mind if I post a CM pre-Block Motor grinder?

I picked it up yesterday from a CL add for an 'Antique craftsman 3/4hp grinder/wire wheel - $25'.

I don't know about antique, but I know a Craftsman Block or pre-Block grinder is worth $25. And that stand was/is a CM stand.

It was a drive in the rain for part of the trip, but it's home with me.

My place in SE Michigan.

Here's a close up of the grinder tag, it is rough and hard to read. I make it a 1/4 HP, not a 3/4 HP. No matter, I was really after the CM stand.

I make it to be a Janurary 1961 model, based on the '1 61' following the 'MFRS. No.'. There was no date visable on the bottom plate when it was removed.

He dropped the price to $20 without me asking. He showed me it ran by plugging it into the porch outlet, I tried the switch and we shook hands.

The CL says there's a new cord. Ha! He must have felt funny about selling this guy with the cracked & brittle OEM-cord. It fell off when we put it in the truck.

Also, no Start Capacitor or Relay. Wiring looks original. Funny thing when I cut the crumbling cord, it had a green ground wire, but the case is not grounded and the aftermarket plug has the ground terminal missing. This guy will get both, along with a new cord and bearings.

Thanks for looking.

I will start a seperate restore thread and put the link in this post.

Edit. Restore link. --> http://www.garagejournal.com/forum/newthread.php?do=newthread&f=4

The rest is there, it's just hiding underneath. I looks like a shadow in the photo.

There was a NOS looking stand on fleabay over the weekend that sold on BIN for $149 if I recall. $20 for the whole package = You ****. :thumbup:

Depends.

I have lots waiting to get the 'treatment', but not as many actually in service as some GJers.

As soon as I figure out how to extend the arbors without messing up the threads, I will turn 2 - 3 into dedicated buffers.

I have an idea that I want to float out for comments.

All the arbor extenders I find are 'smooth bore' with set scres to hold them to the grinder arbor/shaft.

If I was to take a pair of the 'smooth bore' extenders of the approiate size and weld the correct size RH & LH nuts to them -- wouldn't that work?

I'm a newbie welder, in fact a Millermatic 211 is in the box in the front hall, waiting for me to do the Taxes so I can go play. :rocker:

Thanks you!

Now, there is the no small matter of gas; but Mrs. Torqueman is happy because I'm driving less now that I'm retired.

I have to admit, I have widened my search area. Too many guys in SE Michigan are getting to the CM Block grinders before me. I guess I'll just have to .... :3gears:

I wouldn't recommend it.

First - The extension would only be secured at one end, leaving the "business" end to rattle and ****** up the threads.

Second - There is the balance issue. If the nut isn't spot-on centered, it will create a vibration. Possibly aggravating my first point.

-Brent- · Apr 8, 2014

The balance issue came to mind, too. This isn't a terribly complicated part to make. Perhaps someone like Kevin54 could whip you up a few?

However, this would work on the RH side:

Edit: FYI the pic is the link.

-Brent- · Apr 8, 2014

Personally, I'd have one fabbed but there are parts out there to rig one up.

There are the Dayton steel 1/2" arbors and there are steel 1/2-20 threaded inserts. They could be made to mate up. It'd save the threads of your machine but likely cost you more money, time and effort rigging something up that a machinist could do in a half hour.

drivesitfar · Apr 8, 2014

Tourque: do you think we would really tell you not to put up a pre block grinder especially since it has the original Craftsman stand? good luck with that one and i'm looking forward to seeing how well you can make that stand shine in your new thread.

i'm with Brent in maybe PM ing Kevin 54 to make you a couple extenders and pay him for his time and materials. there might be others who can do an equally great job, but i have read a lot of his posts and i wish i had a tenth of his talent. maybe a 2 or 3 inch extension or ask him what he thinks what would work best to make a block into a buffer.

since i own a baldor buffer i can measure out from the bearings on it and my block and give you those measurements if you need them?

good luck and nice find on the grinder with stand for $25.

cbacres · Apr 8, 2014

Nice find Torqueman, I also await seeing your restore of this one.

nine4gmc · Apr 8, 2014

Brent, those are sold on one of the links previously posted for around $10 pr. It would be hard for anyone to whip some of those up for that cheap unless they already have the material and are doing it themselves to save a couple dollars. jmo

I prefer the round top design.

Nine: I agree that the price per pair of yours at $10 or Brent's link for $20 are a great price, but aren't they only right hand thread? you'd still need to have a left hand threaded one made so why not get a pair a little longer and have them made by the same person so they would be identical?

CB: have you turned any of your blocks into a buffer yet and what method did you use or would you use if you did?

nine4gmc · Apr 8, 2014

They come in R/L pairs, specifically for this purpose, in short and long extensions. :dunno:

drivesitfar · Apr 8, 2014

94: I guess my bad. Brent's link didn't say that and i didn't see the $10 link you mentioned which you might have posted a few days ago since we have been trying to make a block into a buffer for a while now.

cbacres · Apr 8, 2014

CB: have you turned any of your blocks into a buffer yet and what method did you use or would you use if you did?[/QUOTE]

I haven't really gave it much thought on converting one, I think I have one to spare for it

. I'd lean toward the threaded units though. My 3/4 HP might make a good candidate for it. I also have a new model CM 8" 1 HP ( so called 1 HP) that might work also.
One thing I do know is, now after reading these, I guess I didn't know I needed to convert one, but here we go :bounce:

Actually, what I posted is a hot rod part. It's a shock mount extension. I don't think they're available in LH thread. However, I'd love to see the extension that's referenced.

Anyone feeling adventurous to wade through the thread and find the link?

You are welcome!

And to all the numerous posters - thank you! Good thoughts and warnings.

drivesitfar - I have some line drawings w/ measurements from newer Baldors, but it's a bit trickey because they do not show all the layout on the grinder and buffer.

So, measurements will be helpful. Thank you.

I must say, when a guy steps away from the laptop for a few hours - alot can happen in this thread.

scroll down

EDIT ON THE PRICE but still cheaper than lathe time.

-Brent- · Apr 8, 2014

94, I've used something similar in the past. However, they're known for not having threads inside. I don't believe any of those on Caswell's site do either.

What I posted, although not specifically for a grinder/buffer, has matching threads inside and would thread onto the RH side of the machine.

I wonder -- would it be cost effective for a 5/8" arbor extension, to buy a pair of these for a smaller shaft and thread to the 5/8" size. Or start with the 5/8" shafts, cut them off at the end of the bore. Then drill/tap for LH & RH 5/8" threads? :headscrat

drivesitfar · Apr 8, 2014

i think i saw some holes for set screws on 94's extensions so they probably don't have threads. or do they?

Tourque: again might be easier to PM Kevin 54 and see what he thinks or how much he might charge for a pairs knowing several of us Blockheads might want to buy some? i don't know Kevin, but i do know he is a quality guy by the information he posts.

-Brent- · Apr 8, 2014

Okay, so if you're wanted to fab something on your own based on stuff that's currently available, you could source some 1/2-20 threaded inserts and insert them into a steel insert (or matching material to whatever the insert is). Then, run a buffing wheel that matches the OD of the extension.

nine4gmc · Apr 8, 2014

This one says 5/8" LEFT HAND THREAD, fits 1/2" buffing wheel. I would assume it has a 5/8" left hand thread inside and a 1/2" left hand thread outside and the screws are to lock it on. Maybe call them first?
http://www.caswellplating.com/buffi...-long-shaft-adapter-5-8-bore-left-thread.html

-Brent- · Apr 8, 2014

No, it's for a 1/2" or 5/8" shaft to be mounted on the left side to convert a motor to a buffer. I bought a set (Dayton's) for a project that I am giving away, it came with an insert to fit a 1/2" shaft or the insert could be removed to fit a 5/8".

torqueman2002 · Apr 8, 2014

I have had unusual success on CL with Block Grinders in the last 2 days.

Yesterday was the 1961 CM 1/4 HP pre-Block motor Grinder, with pedestal/stand.

Tonight, I picked up a nice CM 1/3 HP Block Grinder, model 387.19580. It's not a pretty-boy, but well used and cared for by a 50 year old tool & die maker.

The seller's wife was very pleasant, but held firm (as instructed by her husband) on the $30.

I spent several minutes looking over other listed items, and will call him back on things I need. No really!

Anyway, here is the 2nd grinder (in less than 24 hours) to join the growing ranks.

Taken in my neighbors driveway. They have no clue what I am up to.

I am a Blockhead, Man!

drivesitfar · Apr 8, 2014

Tourque: so now we all know why you were away from your laptop for a couple hours. looks like it found the right guy to make it shine like new again.

Gotcha - I fixed the 're-' part, now it only says thread. Which is what I meant to say, but my post-edit half of the 1/4 of a brain I have left, changed it on me.

I'll PM Kevin and get back with his answer, I think I need a measurement from you 1st though.

drivesitfar · Apr 8, 2014

i'll get the measurement in the AM off the Baldor buffer that already has the wheels off of it. i'll include a few pictures too if the right side of my brain is working tomorrow AM.

I just can't help myself. The Mrs. is a reluctant enabler. She says it's better than me drinking, gambling, or something she calls philandering. I hope that doesn't mean messing around with Phil. :wtf:

that's an interesting find. different mod# than mine, but that same 7561 no. on the tag. mine is also only 1/4 hp.

Torqueman, great find, again.
How many does that come to now?
May be time to stop buying....................not!
So I wonder what tomorrow brings.

Yes, interesting ...

How about a capacitor or start-relay? Maybe the 1/4 HP don't use one? This is the 1st 1/4 HP I've taken the bottom plate off.

The next time I visit my brother back East, I'll ask to open up the 2 CM Block grinders he has.

1/4 HP Model 397.19400, I paid $15 on 7/20/11
1/3 HP Model 397.19580, I paid $20 on 8/13/11

BTW - what's the model number of yours, I can't quite make it out.

I had to stop and count. :headscrat

Let's say that I have never sold any. Never!

I still have my original grinder my Dad gave me over 40 years ago. Li'l Red.

Last August, I picked up a 1/3 HP CM Block Grinder 397.19390 for a forum member.

I am waiting to hear about the 1/3 HP CM Block Grinder 397.19580 I bought 04/07/14. A forum member asked me to look for a Block Grinder (I thought 1/2 HP or greater CM Block Grinder). I overlooked an I/M from him asking what I thought about the very 1/3 HP I picked up, thinking I would keep it.

Long and short of it, it's his if he wants it; or I'll keep looking for a more powerful one for him. Truth be know, if he's like most Block owners, he won't stop with a 1/3 HP; he'll want more HP. :3gears:

In July 2011, I gave my brother a 1/4 HP and a 1/3 HP (397.19400 & 397.19580) paid $15 & $20.

I know I didn't answer your question directly; you could be Mrs. Torqueman! I'll never tell! Never!

As far as what tomorrow brings, I'll be hunting the 'White Whale!' Should others get in my way, So Be It!

Phil uses a stone for his harpoon, no grinders on board.
