Building A Tool Post Grinder

this is the motor for my tool post grinder. 1 1/2 hp , 4800 rpm DC motor off a treadmill. small size, powerful, and light weight.

Very nice so far.

What wheels do you plan to use? Will you balance them?

I have ordered some 3" diameter X 1/2" wide tool post grinder wheels from Enco for external grinding.. they don't need balanced. they are small, not like using a large wheel.
 
your treadmill motor will get pretty hot without any forced air cooling. I ran my 1hp one for a while without a fan and it got too hot to touch after an hours use. Then again, you might not be using it for long enough stretches for it to matter.

oh, and beautiful spindle too!
 
Nice design, Mark. I like the compact nature of it. Brilliant idea to use/modify an existing spindle.

I have a design I've been working on for a long time. When I can, I'll execute it and post as a project. I am pretty sure mine will outweigh yours a good bit lol.
