Most of the grinder machines here have imperial (inch) shaft sizes, so we can't use those particular wheels.
I recommend starting with a 1A1 type shape, and Shars sells them about as cheap as anyone. A 180 grit is a good compromise, look for a 75 concentration. If I was setting a two-wheel grinder, I would go 150 and 320.
Just curious ... l Google'd "Howard Hall Deluxe Grinding table" and was not able to locate any information about it ... other than Chuck has been building one
Anyone have links or references to details?

Howard Hall is an English machinist that has written for Model Engineers Workshop. He compiled his articles into several books, one of which is "Milling, A Complete Course", which was re-published as "Milling for Home Machinists". The Deluxe Grinding Rest is detailed in these books.
Here is a picture of his rest.

Correction: his name is Harold Hall, my bad...
Chuck,
Thanks for the picture. If you had not explained what it was I would have guessed it was a prototype Martian from H. G. Wells's "War of the Worlds".

I just returned from Lowe's with a 6" grinder to pair up with it. I'll put a diamond cup for carbide on one side and a AlOx cup for HSS on the other.
