It's cool that people like longdistancerider put things in that I didn't. The passage of precision mechanical knowledge is one that can't be googled. If it has no resale, it has no relevance... I was fortunate, so my grandfather said... no such thing as lucky. Take note of everything in this forum... and you can't get it wrong. Tourqe specifications are critical... The only thing I can think of now is the use of anti-sieze or lube of some type to eliminate the chatter of metal on metal heat binding. Best thing to do is use cleaning taps and dies on the threads, but they cost money... I have so much money in tools... the wratchet adapter I posted earlier cost me $65... I have three, 2 Snap On, 1 SK, 1/4" 3/8" 1/2", I use em' on T-handles, breaker bars, torque wrenches, and speed handles... I have four speed handles. Mechanics have very little room for deviance... That's why it feels so good to drive the the things you have wrenched on... And can continue to... My 77 ElCamino will break 150 mph... Scares me now days, but fun!!!
