I just dont have the eye's I used to and have such a hard time lining up the threading tool on the ID threads and seeing in at an angle.
Nothing big to this and sure guys have been useing something like it. It just projects the ID thread out to see it better. I just threaded one male and one female 1.062x16. Cut away a section on the female so I can get a good look when setting the tool. If you make them a nice fit it works well.

Re: Handy tool to help catch the ID action thread

It was two pieces. Think of it as a stud with a nut. The stud screws in the action thread, the nut screws on that. The threads are a very close fit so the amount of Z axis end play is very very small and I dont have to use a flashlight and mirror to line the thread up. At one point I was useing my bore scope with the right angle mirror to line them up. I like this better.

Good question.

Oh I see it now, looked like it was all one piece at first, which I couldnt figure out how youd time them without cnc or some kind of wizardry.

Whyd you decide to use aluminum?
 
Re: Handy tool to help catch the ID action thread

I do so few actions as a hobby that 7075 alum will work good for many years. The tool never touches the aluminum piece. I set the threading tool X offset on a test piece then I line up the tool on my Prototrak 1630 lathe, I just have to move the insert into a spot that I can see that the point of the insert matches the thread in Z dimension(which is easy now that I can see the cross section) and push enter to set the spindle orientation, crank out away from the work, remove the alum. piece and push go.
