|Rose Engine Cutter for Fixed Tool Work|
Sharpen the edge to an exactly correct angle is not usually critical. Rather, the overall shape of the cutting profile (as viewed from the top) is more key.
Sharpening with lapping compounds of 6, 3, 2, and finally 1 micron are recommended. Additional honing information is in the Notes & Comments section below.
Some historical information about sharpening these is available on the Ornamental Turning Book of Knowledge.
|Hardwoods and Ivory-like Materials||20° - 22°||This is recommended by Holtzapffel, but if the original angle is different, it is best to match that. Higher angles are recommended for reducing chatter in the cutting operation.|
Notes & Comments
Angles shown are those recommended by John Jacob Holtzapffel in Turning and Mechanical Manipulation, vol. 5.
