FINALLY! i have a place to set up a shop. so after much wait this weekend I am going to tear apart my grizzly and with a little work and a few extra parts make a KMG clone type grinder.

My question is:

the 10" Grizzly wheel is really a drive wheel and normally fits on the grizzly's motor axel by compression with a nut and a washer. which in this set up means no bearings.

I want to use this for a 10" contact wheel attachment so i think i would need to install bearings into this wheel. if i remember correctly the ID of the aluminum wheel is 1/2" and there is plenty of room to drill it out to 3/4" or whatever i need to make bearings and a shaft fit for the tool arm.

do the bearings just tap into the center? adhesive or what? ive never installed bearings like this before.

Am i way off base in my reasoning? id rather not purchase an expensive wheel if i can make this work. I am not sure how precise i need to be with opening up the ID of the wheel. should this be machined, or will a drill press work fine. i dont want the press to find its own center, which may be a bit off, there by cuasing the wheel to wobble. maybe im over thinking it.

Thanks for the help.
 
You can not do it yourself with the equipment you have.

It is very precision work and you will need to find a machinist that can mill it for the bearings.

Or you can mount it to a short shaft and then mount that shaft to pillow blocks on a tool arm.
 
I'm with AVigil on this - if ou want to go the bearings route, you'll have to have it done. the drill press just isn't accurate enough. I think the easiest way to make it work is with pillow blocks on a tool arm, as mentioned...
 
+1 on what was already said. The best route is to get a shaft/pillow block set that will fit the wheel without having to bore the center. Boring it for bearings is a job for a machine shop, a home boring job will probably give you a wobbly or non-concentric contact wheel.
 
there have been a few threads here on the forum about guys using the grizzly 10'' wheel, and they all went and had bearings put in and it never sounded like very much, i would take it to a machine shop and have it done. i think you would be happier than going other routes.
