Thread cutting?

[MoeMag]

I had a really great site bookmarked with all the info needed to cut barrel threads... but I cant find it!?

Im looking for info on mainly cocker threads for barrels. Angel detent threads would be helpfull too.

The tap used to cut autococker threads is:

15/16"-20, Oversize GH-7

The tap drill is 15/16" minus 46-50 thousandths.
