I'm not real impressed with 1/2" arbors extended out that far. If it were the cap-start version, it would at least have 5/8" arbors. Does look like they were cut off a bit. Still, a very nice and well executed setup.

I would think the base of that whole setup would just get in the way of polishing. It would be cool to see a setup where you can get a large part under to polish and still have dust collection. I have only polished small parts so I could be wrong.

TM: i think i'd put the $250 towards a 3/4 HP Baldor buffer, but that is interesting.

It is a 3/4 HP Model 397.19470 Crown Top Commercial dual voltage with an old cast iron roll around stand.

$35 - and I am happy, fine price for a fine machine.

Yes they are. Some may find 7" wheels difficult to source locally, but MSC has them. I've had good experience with ordering from them.

Do you still have this grinder? Are you sure it is a 7" and not a 8" grinder? Happen to know what bearings they use?

Pretty sure all the blocks up to 3/4 hp use the same 6203 bearings. Never seen a 1 hp, but probably also use the same bearings. These are fairly lightweight motors, and they don't require bigger bearings.

I just measured an almost new, original 3/4-HP m-397.19470. It has 8" stones.

I don't have anything in my database about the exact replacement bearings. Sorry, but they are most likely the same as 1.0-HP 257.191600. Measurements in the chart are in mm.

I just saw maxima's post, 6203 is what I used, the suffix is for sealed/shielded or something I don't recall right now.

Thanks guys. Trying to revive a real sad one.

You are certainly welcome. But, .... don't forget pictures and the more the !

 

[zkling]

Have any pics handy of your almost new one? The major problem I need to figure out is that the left hand side arbor threads are stripped. Typical craigslist idiot/liar seller "runs good".

Runs good covers a wide range. I have a couple of grinders that do run good, but still need TLC. There's even one with arbor threads that need cleaning up.

A split LH die like this one from MSC may help with the arbor threads.

Best of luck, let us know {with pictures of course } how you make out.

Ah, that's nice. Explains why I couldn't find it when searching. Unfortunately the threads on this are worn beyond the minor diameter of the thread, let alone major diameter. Additionally someone cut flats on the end of the shafts with a grinder. Again it's real sad. I just wanted the stand it came on (atlas).

If it's a 3/4hp, does it have a 5/8" shaft? If so, that same shaft was turned down to 1/2" for the 1/2hp and below models. The trick would be getting it into a lathe with damaging the rotor. Just a thought.

 

[zkling]

I'll have to look at it closer, it got put away quickly. I've got a number of pressing projects at the moment, so it is on the back burner. All I remember is that it is a 8" unit, but the left hand threads are done. O and it is missing one wheel flange and the light socket (no biggie). I thought about building it up and turning it back then threading, but just have so much going on right now and don't really need another grinder or project. Just wanted the stand.

At first I thought it was just a larger HP version of the common 1/2hp commercial 7" units, but after realizing that the guards were larger thus 8" wheels, I'm not sure what all is different.

I have flats on my 3/4hp, 8" 5/8 shaft. I really like them and wish the 1/2" arbors had them too.

Those are nice, the ones on mine look like ol' Jimmy went at them with a hand held grinder.

I just bought an old Atlas grinder with stand as well. What's your stand look like? Is it the 3 PC design?

 

[bagged89s10]

Sure. It has a homemade belt on it.

What parts did you use to make the belt sander attachment? I'm either going to make an attachment on one of my blocks or look for a CL deal on a disc/belt sander.

Mine looks just like this, right down to the thick green paint. I think it is only two pieces. I would like to find a matching atlas or black and decker grinder to go on top. I'll get the number off of it.

I think mine is slightly newer, as it's not "Art Deco". Guessing late 40's. It's too buried to get a pic at this time. Good luck finding a matching grinder!

What parts did you use to make the belt sander attachment? I'm either going to make an attachment on one of my blocks or look for a CL deal on a disc/belt sander.

I bought a contact wheel from Grizzly, and fabricated all the other parts myself.

Do yourself a favor and build a either 2x48 or 2x78 stand alone unit.

You're saying not to put one on one of my block grinders?

[exmaxima1]

Depends on the needs or application. Minimum cost will be $500 in parts to build a stand-alone machine. Many users are very happy with a $200 Multi-Tool adapter on their existing bench grinder. Or a $200-300 Kalamazoo.

 

[7th Kahuna]

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 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.

 

[altersaddle]

This looks like a Craftsman stand wearing a table-saw hat:

7th Kahuna: You should be able to fabricate tool rests, spark arresters and eye shields fairly easily, until you find a donor.

 

[McBrownie]

...after a quick 20 minute Simple Green facial isn't looking so bad aside from the giant rust spot.

That center tin is an easy fix and you'll have a very nice grinder. There are shaft extenders available if you want to turn that into a buffer. Also, that lamp is a rare one. Nice find!

Yes, some sanding and paint and the center tin will be great. The label itself is in near perfect condition. To remove the label, I assume I would drill out the rivets from behind. I would hope then that hammer rivets were still available. I would hate to use pop rivets.

There are shaft extenders available if you want to turn that into a buffer.

No need for a buffer, I picked up a proper Rockwell buffer last year. It was really nice to pick up a tool to help with the restorations for a change, as opposed to just another 'to-do' project.

Also, that lamp is a rare one. Nice find!

I was unaware the lamp was a rare one, but I like it. I more-or-less finished cleaning it up last night before I came in. It was a little smashed but I was able to pop it back into shape really easily. You'd never know it had been out of round.

Thanks

I wouldn't bother removing the label. Just mask it off and spray over it.

I rather try to find one on CL or make an attachment. My goal is to spend under $100.

So I guess I have to keep it now. No I didn't break anything.

Check out the 'born-on' date stamped on the bottom:

April 10, 1972

That would be 42 years ago, to the day, yesterday, the day I bought it.

Seems it was meant to be. I guess yesterday's Simple Green facial was well deserved.

Anyhow, now before I do break something. Does anyone recognize this?

I know it's a bushing but it looks like it could have been crimped on. Within the band it says 7/16 U.S.A.

Now as this is a 1/2" arbor, I'm a bit confused. I don't specifically need to remove it at this point but cleaning the housing would be easier if I could. Anybody know how to get it off. Can anyone confirm how they got it on there?

At this point it's not budging.

Thanks
