Normally I would use an oilstone for the polish but didn't have one on the farm. It wasn't really a grind. That surface has to be flat, not concave.

You are right1 if you are caught using the side of the grinder on a government job you gat your a$$ chewed out or worse! I have never seen this but they say it is safty measure and that the wheel can break up hurting someone. I really don't know but I worked on government jobs and that was the rule.

You might notice, I was putting a shine on the surface, not grinding as was evidenced by the pitted portions still visible. I've had that stone since 1971 and the way I grind, I've only had to dress it once with a wheel dresser, not a diamond. I've never had obvious wear on the side. In the school situation, I've only had to dress stones used by other teachers. I've also used horizontal surface grinders and as usual, wear patterns are determined by the operator. www.tilgear.info/product_images/Large/WTG144849.jpg @@mattedwards4533

@@alanvaleandthelazyfarmer1930 In my shop I do it too. It is like all government agency, nothing much to do and over staffed. So they come up with trivial things to put in the rule book to appear to be working.

The more you heat the second time gives you a softer finish. If you polish the metal before tempering, you can get a brilliant finish like chrome exhaust pipes or gun barrels. The annealling process of complete softening is where you heat to red and cool as slowly as possible. I used an enamelling kiln and switched it off leaving the metal in there. If you heat copper to red, it will be soft no matter what you do. You harden copper by hammering.
