Looking at getting a variable speed Delta 6 inch bench grinder (Model 23-196). Only $79.98. Wheels are 3/4” wide, and I would replace one with a white wheel. Speed goes down to 2000 rpm per listed specs. Anyone use one of these for grinding lathe chisels? If so, how does it work at lowest speed? I think most slow speed grinders are at 1750 rpm.

Any others I shoud look at in that price range? I have been using an older small powerless grinder (6” x 1/2”) for my scraper, and my Shopsmith Strip Sander for the other lathe chisels. Shopsmith seems to work okay, but, I wear out the belts quickly.

I bought an 8” slow speed but if I had it to do over, I would buy a belt sander.

I made a grinder that runs between 1700 and 1800 rpms, I don’t think 2000 would be two fast. The problem with standard speed is it over heats the edge. I mostly use a belt sander with 80 metal belt.

Thanks, Rick and Karda. Maybe I should just stick with the Shopsmith and buy better belts for it. However, I do have a nice old stand (pedestal type) that I would like to put to use. Also, I could use another more powerful grinder than the one I have now for general grinding duties. See how I am trying to justify another tool (big grin).

I just bought this one and it works quite well: https://www.amazon.com/gp/product/B015U2STNM

The reason that I bought this one:

1” wheels
1750 RPM
80/120 grit wheels

I’ve been using it for about 2 months with a wolverine jig and it’s doing a great job.

Paul, that Powertec you got looks pretty good. Already comes with white wheel and they are 1” wide. By the time i bought 1 white wheel, I would be into it for the price of the Powertec. Thanks. I will put that one down as a potential.

I just wouldn’t advise buying a 6” grinder. The smaller the wheel the deeper the hollow it leaves, which gives you less bevel to rub. Recommend at least 8” grinder and 1” wheels. Best of luck to you!
