Greetings all; Is there documented someplace where I can grab a copy and print it, a method to calculate the major and minor diameters of a thread that is specified only as 16 tpi, pitch diameter 0.965"?
I got out my calculator and came up with a figure of 0.926" for the minor, but when I quit boring at 0.917 last night and switched to the single tooth threading bar I'd made, the nut fit the threads while they were well under 50% cut! Very sloppily too. So when I turned it around to do the other end, I measured the nuts exterior threads and came up with about 0.878" so I bored that end to about 0.865" and started threading. This end fit better, but wasn't even close to having sharp inner peaks yet because the starting diameter was still too big, leaving a very noticeable flat. -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
