Hi, I\'m new to the forum, but I\'ve been lurking for about a year. I\'ve been a machinist about 24 years and have finally collected some equipment for my home shop.
I began work on my carrier block recently, and not having a rotary table here I did the trig for the bolt pattern to drill and bore the .420 and .280 bores. I then made up a simple indexing fixture with a 3/8\" shoulder bolt and a .420 pin to mill the 10 flats.
The hole cooridantes from center are below if anyone can use them.
1. X.0 Y1.0
