If it won't pull off, I'd cut most of the way through it with a dremel cut-off wheel. Then pry it apart with a screwdriver until it splits and opens up to get it off.
let's see your craftsman block grinders

The Dremel is a really good idea. I finally acquired one several months back and don't think to grab for it yet. I was anticipating having to slit it by hand and hoping it would be soft.
Look what followed me home yesterday.
I need a grinder , not a buffer so I guess I have to decide if I want to look around for a donor machine as I am missing the eye shields, tool rests, and spark arresters. I guess I'll pull it off the stand today and see how she looks inside.
Nice setup.
No way, with a little sourcing (used motor, repurposed contact wheel) you can get in right around $200.

After a long time spent following this thread, I finally bought a 1/2 HP block grinder offered for sale locally. It was in decent but dirty shape, and was complete with the exception of the quenching tray. Although I have a decent bench grinder, I wanted to have a dedicated buffing setup. With the great advice and wealth of information offered in the forum, I was able to refurbish the block grinder and set it up as a buffer without the wheel guards and eyeshields.

Nice job! I like the colors.
Thanks for posting, the shout out, and a big welcome to the GJ and this great thread!

I guess if you already had the pulleys, bearings, shafts, belts, hardware, steel tubing and bars. Plus access to cutoff saw and mill. And can weld. Then I guess so....

If I only had extra pulleys lying around I could just make the belt sander attachment for next to nothing like the guy on jalopy journal did.

You are making way too much out of this, no need for a welder or mill. A hacksaw and a drill press can easily build you one. Pulleys aren't that expensive. Look up no weld grinder plans. The biggest cost if purchasing new components is the motor and contact wheel.
I've built numerous belt sanders/grinders, and from my experience the versions that were built onto existing grinders were the smoothest & quietest. I hate using machines that require earplugs. I would not expect a low-cost no-weld design to be significantly better. I own a 1.5hp Baldor 2x48, several Kalamazoos, a Baldor w/Multi-tool, a CM 2x42, a stand-alone Delta 1x42, and several home-brews. My most used is the grinder with the Multi-Tool as it plain does the job. The typical user would be thrilled.

I checked out that DIY belt grinder, and it is not in the same league as a Multi-Tool. There is no tracking control, so you run the risk of throwing or tearing a belt. No tensioner, so it is slow and awkward to change belts. But most important, the drive wheel is too small---way too slow for efficient grinding. The drive wheel should be at least 4", and ideally over 5" for a 3450 rpm motor. If you opt to emulate that design, and have access to a lathe, buy a solid rubber caster wheel to machine a drive wheel. Basically like Kalamazoo does with their commercial units. Works great!

(I hope this is ok to post here. Normally, I wouldn't post about something I am selling, but I figured one of y'all might need these. If it's not ok, I'll delete this post upon request.)
I am selling a pair of inner wheel guards on the classified section here. They're both cracked, but intact, so if you are in need of some to go on your grinder, and aren't picky about how they look, check out the listing. Asking $15 plus shipping.

Has anyone made replacement parts for these grinders using a 3-D printer?

If they have, they're keeping it a secret to avoid GJ members from harassing them for parts.
Kahuna, you got that grinder from lake Isabella (spellings)? I had my eye on it and today the cl ads was deleted. You ****!Look what followed me home yesterday.
I actually only bought it for the stand. The grinder looked to be in pretty rough shape. Paid $40. Figured I could resell the grinder itself.
Unfortunately, she spins like a top and after a quick 20 minute Simple Green facial isn't looking so bad aside from the giant rust spot.

I finally got my first CM block grinder. It is a bit sad and will need new glass but it runs great. I rescued it from a basement at an estate sale and looks to have been idle for many years. And to boot it was the last day of the sale so all was 50% or more off. Got it for $7.50.

Nope, can't blame me for that. Mine came from El Monte. Had I known however . . .
In cased you missed it above, You ****.
Nice find.Between grass cutting and other misc need to be done today; I found a little time to do a disassembly cleaning and assessment. After blowing out the inside it runs pretty smooth stripped down. It will need at least the left side nut and one wheel flange. Worst case if it doesn't hold as is, a good suggestion was to turn the arbor down and re thread like the 1/2hp units. I'll try to get a file on end flats tomorrow.

I recall you saying it was 'a sad little grinder', but the pictures are something else. What did they do to it? Wow.
The strange part is the nut for that side is pretty much smooth inside. You have to push and thread for it to somewhat catch. There was supposed to be flats on the end to help secure the arbor with a wrench while loosing the nut. Unfortunatly someone used pliers or the like instead of a wrench and destroyed both ends of the shaft. The right hand side is salvageable, threads and all. I'm going to try to go at the left hand threads with a chisel and file to see if I can raise them enough for a new nut to catch. Worst case I could turn it down like the 1/2hp units are, but then all the 8" wheels would need a bushing. Not sure how much of a benefit a 3/4hp will be over my current 1/2hp unit. On the plus side it was complete minus the light shield. For the same money spent, I would have rather had your grinder on my stand.
O well. Anyone have a specific recommendation for a left hand nut source before I go to fastenall or mcmaster?

I sure looks like someone was taught "righty-tighty lefty-loosey" and had no knowledge of left-hand threads. They had to work hard to make that mess. I picture big vice grips on each end, a big wrench, and lots of swearing.

Yours and Marty's have each helped me to appreciate the condition of mine a lot more.
I had my center tin soaking in vinegar for about 30 hours. I'll need to give it a good brushing and see what I have to work with. It is going to have some pitting. Other than that, the condition is exceptional.
As for your nut, my vote would have been McMaster. Good luck with those threads.

I pulled the guards off and grabbed some casting numbers. This is for the Canadian 1/2 HP, model 397.21145
That's a 2 4971515 on the body and 3 4971514 on the cover. I didn't pull off the left side to check the numbers. But I did find the birthday!
May 14 1974.
I managed to find the 7" wheel at Re-Store too, so I've put that back on. It's pretty hard to find 7" wheels locally - KMS is the only store with stock ($45 and it's a green wheel).
I dressed the wheels and we're running pretty smooth. What is a good way to check the bearings?

The first way to check the bearings is by ear. Do you hear a crunchy noise when you turn the wheel by hand ? when the motor is running ?
Another sign would be if there is "chatter" on the arbor when running the grinder with the wheels off.
Is there any play in the arbor when you push/pull/lift it by hand ?

Well, I missed out on what looked to be a nice unit with a stand, may have even been a Craftsman stand, but the pic didn't include much of the stand. Somebody scored a nice deal, $75. Not as good as the $7.50 deal above (btw, NJ Marty, you, sir, do in point of fact, ****!), but if the stand is OEM, then it would've been a great find for me. It was just too far way to have snagged it last night, and this morning its gone.
Sigh....

Not guilty. Today, and yesterday he was TaxMan2002.
Today he got a 1/2 horsepower. You had to go one more bid didn't you?

Yeah, it's weird that they didn't show bidder numbers instead, or at least obscured the user names. I've lost auctions on a few things to guys on here, it's all good. My apologies for making the sale price higher, but I did want it! I did win one other thing, I'll keep an eye out for a guy carrying a grinder out when I pick up.

Marty: you might have been ok with that purchase of $15.00 for your 1/2 HP commercial grinder with all it's parts except for the water tray and then to get half off too is just ridiculous. did it really not sell in the first day or two of a sale? in any case since you have a 3/4 HP Dayton let us know how you like your block and if you can tell much of a difference. also the Dayton should clean off the block nicely.
Riven: i do like those 1/2 HP commercial blocks and rarely see one for sale since i finally picked up one over a year ago. nice find and will it kick another brand grinder off the bench or just have a couple more different wheels in your shop?
TM: the guys should know better than to try to buy a block (any block) in Michigan without going through you. nice find and hope the tax man didn't take too much of your block funds.

Shadow: you have to be quick and if i remember correctly you bought a block on it's original stand for $30 very close to his house that might have got his taste for buying them up again. i was helping him try to just sell before you posted that one. you just might not get another one now because i hear he has a lot of relatives wanting block grinders.
good luck and I've still got my money on the King of the blocks (TM) and God help the Canadians if he decides to drive up there or if he finds a good shipping company.

OK, OK. I hear all y'all.
But I swear, they're NOT for me!
And any CL grinders are offered up to the members on the W/W List.
That said, the following 1/2-HP m-397.19441 is not a CL find, but I want to post it up, since the Block is out of the bag, in a manner of speaking.
{I will be showing/offering a 1/2-HP CL find to the W/W List guys later. I've just been a bit behind with other distractions.}
As you may know, the 1/2-HP and it's bigger Block brothers, have not been making frequent appearances on SE MI CL lately.
This guy is going to a good friend and former work buddy.
Those wheels sure look like this guy's been used to grind pieces of wood.
