Brainstorming
#10
When I learned how to grind HSS tool bits (MR A School) I was first required to produce one with acceptable angles from 3/8" sq 1018 steel.  I did the same with my students when I taught machining at a vo-tech.

You can obtain drawings with the recommended relief angles in South Bend's "How to Run a Lathe" booklet or in the US Navy's Machinery Repairman 3 & 2.  The latter is available as an on-line PDF.  IMHO both books are must haves for every machinist.
