I got this grinder when my Dad passed away. Is it worth trying to fit 6" CBN wheels on it or should I just get Aluminum oxide wheels or just junk it? I already have a Rikon 1/2hp slow speed grinder with CBN wheels.

I heard Baldor are good grinders so I didn't want to just throw it away unless it's no good anymore.
 
I don't have experience with that model, but I suspect that you'd have no trouble finding a new home for an old Baldor grinder if you ultimately decide that one isn't for you. I think you'd make quick work of it via either Craigslist or Facebook Marketplace, for example.
 
If your Baldor grinder runs, I suggest outfitting with aluminum oxide wheels. There are a fair number of things that I grind that I wouldn't want to use CBN on. Lawn mower blades were top of mind with me. I'll also do the occasional metal fabrication project mild steel mostly, but aluminum also. I recall aluminum being a no-no with CBN (clogs up the wheel).

Good luck. I agree with John above, if you decide to part with it I will find a new home quickly.
 
Chances are that with a Baldor grinder, you will wear out before it does, yes, they are that good and heavy duty. I would suggest hanging on to it. If you want or need another grinder for your turning tools, keep it and put CBN wheels on it. If not, it will sell quickly.

I'd also go with the AlOx wheels. I use the 1/2 speed grinders for sharpening but get a lot of use for the full speed grinder in my little welding shop.

Yes, if you decide to list it for sale it probably won't stay around long!

First, look up the price on a Baldor 612 grinder. It may be more than the basic model. It could a Baldor 623E.
The price will tell you the quality level of a Baldor.

I love putting a toolroom cut-off wheel on one side. The only one to get is the Norton A60 OBNA2. Cheap cut-off wheels don't work nearly as well. Been there. There's a cheap junk wheel on the bottom grinder . It was an early restoration.ba1.jpgba2.jpg

I do keep a small Delta grinder handy with a wire wheel on one side, and a 60 grit wheel on the other side. I don't use it a lot, but I do NEED it from time to time.
