I am building a boring head and need some help with the feed screw graduation markings.
I am using a 1/4- 20 feed screw and as I am no math whiz I need to know how far the slide will move with one revolution of the feed screw so I can come up with some sort of graduation markings. 1 thru 10, 1 thru 20?
Please don't post formulas as I have never learned how they work. They look like Greek to me. I just barely was able to do addition,subtraction and multiplication. Pre so called "New Math" of the sixties.
Will post pics of boring head soon.
