drives does your 3/4HP Baldor have a 3/4” shaft like mine?
If so I don’t seem to see any 8” Nyalox wheels with an arbor size that large.

LIS: I can't recall at the minute whether my big Baldor buffer's arbor is 3/4 or 7/8, but it is big. I also have those hard spongy wheels (forgot what they are called at the minute) that will fit my Baldor plus a box of buffing wheels.

THANKS DOC!!
my old baldor buffer might not be per se vintage, but it's a beast and did a lot of good work before it became mine where it will do a lot more and probably last me the rest of my life.

I got a question for you guys. I currently own a flat top craftsman commercial bench grinder 1/2HP with 6.2A but have the opportunity to buy a wissota and baldor bench grinder. The only thing stopping me is the power ratings on them.
The wissota is a 1/4Hp with 2.2amps, baldor is a 1/3hp 3amps and they seem to go for high prices. Are these strong enough to use wire wheels on, and would it be able to replace the craftsman I own? Or is the craftsman just not rated correctly? I really like the wissota and it’s cheaper I just don’t want it to be underpowered. Let me know what you guys think, thanks.

your Craftsman block 1/2 commercial grinder with a wire wheel should be plenty good to do the job, but honestly if you wanted to push your item in real hard you can stop most any grinder until you get to 3/4 and 1 hp on a good one.
speaking of a good one a nice BALDOR is hard to beat so unless it's been abused that would be my first choice if they were all priced the same. Baldor grinders seem to be able to run 24/7 all week and still work great, but a lot of old grinders on this thread seem to be right up there and maybe a few better so do more reading while you have some time.
the little Wissota for smallish jobs should be fine but not as good as the 1/2 Block you already have.
I'll let the engineers and electricians explain the AMPS and such if they see your post.
good luck!!

Neither the Baldor or Wissota are optimum for any heavy wire wheel duty. They are best suited for typical sharpening and deburring tasks. I have a small Wissota-made grinder rated at 1/3hp (which I thought was the smallest they made) and it won't win any contests for power. As Drives said, use the CM for that application.

Just recently picked up this "beauty"- anyone got info's on these "Union" grinders?.
Quality British engineering.
That one is quite a large example, they are still quite common machines to find used here.
If you change the drive belts try to get a matched pair.
Motors are easy to swap being a standard item fitted in the pedestal.

Just picked this Milwaukee 1/2hp 7” model 4981 up, I thought they were made by wissota but it looks a bit different. I found some pictures of an older Dayton that kind of looks like it so I’m thinking it’s made by doerr? Let me know what you guys think!

Just tore it down a little bit and I’m 90% sure it’s a Dayton/doerr. The wheel guards and rests are all aluminum. Anyone know how I can find out when these were made?

Nice grinder! The sticker surely looks later model, but I have no idea when that might be. I would guess 70s vintage.

I have a few. I need to get some parts I’m guessing, like a few safety shields and new wheels on a couple of them. So a few questions...
1) which units would be best for grinding and which for buffing (1725 rpm vs 3450 rpm)?
2) age of the little Craftsman mounted on the stand?
3) good wheels to use but not crazy expensive? None of them were over $50. They’re hard to resist when they pop up in my feed haha

Yes, Milwaukee has used several makers over the years, and your grinder is made by Doerr

I know the thread is old, but if you never got an answer on the grinder stand, its a 70's Rockwell pedestal.

I got really lucky, this guy was selling off his step fathers tools and he just had it listed as a “buffer” and was able to pick it up same day for $50. It’s missing the outer covers, a tool rest, and PO cut off one of the bottom of the inner cover for clearance probably. I can’t wait to open it up and repaint it.

Gotta bunch but picked this one up recently for $50. A Rockwell "23-200" 7" grinder. 1/2HP. Single phase with Twin-Lite safety shields and water cup. Runs great
The interesting part; on the front plate above the Rockwell logo its marked "23-201" but on the back plate its marked "23-200". Motor made by Marathon
Here's a cool Rockwell product catalog, on page C5 is my grinder. If you like Rockwell, you'll dig this PDF. Warning, its big.

I may have already already posted a pic of my 3/4 HP Baldor with the OEM cast iron pedestal. It’s the one on the right...

Interesting wheel on the right side. Looks like a rubber wheel with a sanding sleeve. Where would you buy replacement sleeves for that?

MAC: great looking grinder. did you get it spiffed up and running? are you keeping that sanding wheel?
LIZ: always nice seeing pics of your shop. OMG that looks like a fun place to do a little or a lot of work.
MtGrizzly: first of all YES Craftsman made 1 hp block grinders so best of luck finding one to add to your group. also wondering why you have so many grinders mostly set up with stones or is your plan to change out a few wheels?
CCog: great looking grinder and nice stand. I also like the metal cans next to it.
JD: I've seen some new members post pics on their first post, but honestly it's easy to get in a few posts if you want to learn or share your wisdom just spend a few minutes reading threads about things you like and make a post thanking the poster, asking a question if you have one or answer a question if you know the answer cause we all have questions. then post some pics if you have some to share.

Thats a good question, I was scratching my head trying to figure it out, there was no name on the drum which is old (but still good) but I did find these and maybe an early version of it?
https://www.eastwood.com/eastwood-expander-wheel.html
Sadly, they're very proud of their 1.5"W x 6" Dia. sanding belts and asking $13. each plus shipping,
https://www.eastwood.com/expander-wheel-band-trizact-a160-100-grit.html
I'll have to find another source as several companies do make custom spec TRIZACT sanding belts rather inexpensively. Could be a cool and useful sanding disc with the right belt, if it was cost effective.
Thanks Drives,
I'm not sure, it now has a new power cord, I don't really use stone wheels anymore since I have several belt grinders and haven't really looked back since and this one is missing the tool rests so most likely will become a buffer without guards and lamps mounted.

Fabulous grinders, great grab. I’ve had seven over the years and managed to hang onto four of them.
If this is your first of these, a couple of things to keep in mind. Be careful not over-tighten the tool rest holder, doing so rather easily breaks off the lip that grabs the holder. Same with the lights, they are just potmetally-stuff and they can be stressed somewhat easily. DAMHIKT
If you have a lathe, or access to one, truing-up the flanges will vastly improve or eliminate wheel wobble.
Great grinder, have fun with it!

Thank you Matthew,
Yes, my first Rockwell grinder (I think, does Walker Turner count?), unfortunately this grinder is missing the tool posts and tool rests and end covers as seen in the pics. FYI: the table mount post for the Delta 1" x 42" is the exact same part as the Rockwell grinder tool post and yes, you have to be careful tightening too much.
It runs really strong, ultra quiet and smooth (balanced). Because the tool rests and end covers are missing, I'm going to convert this for wheeling (no lights or covers) and have already planned to mill some spacers from the wheel all the way to fit into the pins so I will not need the stock flanges but thank you for the tip, I'll check that out.
I'm jealous you have four of them, They must look really nice as a grouping.
Cheers
I would say that your old W-T is not like any Rockwell grinder. Your grinder was made by Kingston-Conley, the same company that made all the Atlas/Skil/Stanley/Miller-Falls grinders in the late 40's thru early 50's. Those are very heavy and powerful machines, and much different in design than the Rockwell models. AFAIK, Rockwell made their own machines (and branded some as Walker-Turner after they bought them in 1956) but used motors from various companies such as Marathon and Baldor---but none from K-C. I've owned a number of Rockwell grinders, all excellent, but they were completely different beasts from the Kingston-Conley units.
