New 12" Disc Mounted on Grizzly Spindle/Disc Sander

I put on a new 12" disc and have an extra over on the shelf near the wall of sanding belts.

Let me know if there are any problems. I just put a 120 grit on rather than the 100 grit that was on there, because I just picked something middle of the road. If most are using it to remove a lot of material, then maybe I should put something more coarse on there.

I’m also adding a page to the wiki, since it was not listed.
