mounting a 7" grindstone on a SS

In a thread about adding a drill sharpener to the SS, I show a base made of wood. I also wanted to make use of several 7" diameter grind stones that I have. The wood base can also support a Lee Valley work rest. To install the grind stone shield, I started with the drawing in PTWFE of the buffer shield and modified it to give access to the set screw of the universal arbor I used to mount the stone. The shield is about 8" in diameter. The shield is screwed to pieces cut from a 2x6 and 1/2" plywood and mounts to the quill. It can be rotated to expose more or less of the stone. Please see attached photos.

Kudos, Peter!:D and an ATTA BOY!!

You are a much better machinist than I. Would liked to have figured a way to do what you did, but settled for the Shopsmith grinding attachment and bought just the tool rest portion of the Lee Valley rest. I'll post a photo one of these days.

I am looking at the on-line vs of PTWFE and not able to find the buffing shield you talk about.

The drawing is on page 150 in the hard cover PTWFE book under "Finishing Metal". I do not know if it is in the on-line copy.

Thanks to Charlese for your note. I also have the SS guard for the 5" stones but I had 3 of the 7" ones in various grits so wanted to have them usable too.
