Hi Rob and scrounger, The angles I used are 2 degrees, 5 degrees and 30 degrees. The cutting tip to the center of rotation of the mill is 2 deg, so that only the tip of the cutter is doing any work. The clearance from the cutting edge to the heel is 5 deg. and the back clearance from the rear of the cutting edge is 30 deg. In my next post, I'll try to get some ACAD drawings in to show details. The numbers are from a website http://getmachinetools.com/pro1113095.html I found while researching this project. My selection of mills are short (dimensionally speaking) and mostly 3/8" shank, so I didn't see the need for a support column found in commercial designs. This kept assembly simple. Now that I know it will work with the right grinding wheel, I need to make some more tool holders for my 1/4" mills. |

I did these a while back, and actually shows the original sharpener. Bogs |

Thank you Grinder and John. I think I will put this on the "I am bored" list. Not to be confused with the act of boring which can refer to metal working operations or, at certain times, conversation. Lee |
