Mr.Conover,
I am trying to teach myself to “turn”. I have read your book on turning (The Lathe Book) along with Dale Nish and Richard Raffan.
My question concerns the face of the skew chisel. How flat does it have to be? Is a hollow ground face acceptable. What about convave or convex faces? Also, is a grinder wheel “face finish” acceptable?
In Mr. Raffan’s book ;he states that it is and the honing procedure is long compared to the time the chisel will remain sharp.
Your comments and advice will be welcome and greatly appreciated.

The skew requires a flat or very slightly convex grind. Hand sharpening on stones usually archives the latter and when the bevels become too convex it is time to return to the grinder. You must use the side of the wheel to achieve the flat grind and this is a concern of the safety people. The practice is safe if it is done with moderate side pressure on a wide grinding wheel. I would not do it on a wheel narrower than 1/2". If you hollow grind the skew it will be appreciably more catchy.
With best regards,

Mr. Conover,
Thanks for the commrnts. It clears up a lot of confusion that i had from the opinions I read. Flat grinding seems to be supported by you and in Dale Nishes book
Agaig ,Thanks very much

Most 18th, 19th and early 20th Century Texts say flat grind as well.Regards,

Mr. Conover,
Thanks for the second message;it really solidifies the right approach to take. I can turn a decent bead and am getting better with each session. Now I can concentrate on the turning and not be confused if the skew was properly sharpened.I received the Veritas motorized sharpening system for XMAS. This should prove useful,if I can jig the skew .
Very respectfully
