here's one for you guys

tried to put a helicoil into the transmission without removing the mount

only issue is, I didn't have a handle the tap fits in...figured it out though
(turns out the square end of the tap fits in a 3/8 drive extension)

A friend taught me a "tap trick" from the old days, he had friends that were and he worked part time as a millright along with driving a Pettibone loader and a few other things.

You get a collection of taps, you get a collection of nuts, different sizes and different THREAD, because USS and SAE are of course slightly different actual size. You can put the tap and nut in a vice, and with the proper size nut, simply PRESS THE NUT ONTO THE TAP and now you can use it in a socket or box end!!!

These two nuts have been on these two taps SINCE THE SEVENTIES!!!!
