Gang,
Getting ready to turn down a couple of my barrels for threading this weeked - been waiting to get my "Thread Alignment Tool" kit in from Precise Innovations (formerly known as Dyna-Systems) and it finally arrived! More info here: http://www.dynasystems-ltd.com/threadingkits.htm
There's instructions on the website on how to use this TAT, but a picture would surely be worth 1,000 words, but anybody's done this and snapped a pic while they were at it.
Bueller? Bueller? Anybody? :)
