Bench grinder parts?

[no704]

So I have acquired a 7” Rockwell bench grinder w the pedi stool. 110/220 in nice shape and works. However not included were the dish washers and spindle nuts. The washers I don’t think will be too much of a problem. But the nuts appear to be 5/8-12 square thread.
Anybody have a source for these? Of course one is left hand!
Thanks,
Neil

I owned a few of those Rockwell grinders. The outer washers will be no problem, but if you are missing the inner flanges with the extended bores you will need to search the auction sites or machine them. Without pics it's hard to confirm what model you have, but mine had keyed inner flanges.

I have no idea where you would source the nuts.

I would try Delta first. Then Mcmaster/Ebay.

I just got a Baldor buffer and also had to make the flanges and buy the LH nut (had a RH amazingly). Mcmasterr only had 10 qty, but I was able to get one on Ebay.

Here's some stuff:

I had a similar issue when I re-built an old Dayton bench grinder that I picked up at a swap meet in that I had the RH spindle nut but not the LH. I was able to find the LH nut at my local mom and pop hardware store in the specialty fastener trays. The big-box stores did not have the reverse threaded item.

Mcmaster Carr will have ACME thread nuts.

I have the inner flanges. Need the nuts. I have searched the Internet. No luck finding anything in 5/8-12 left or right hand.

Are they square threads or acme?
