I used an old paintball barrel for practice this time. Also I reground my tooling and more accurately set compound slide.

and maybe you wont. I just looked at his profile and he hasn't been around since January. I hope he is OK. He did a lot of high quality write-ups on his projects.

I found some errors in my tables. It turns out that the recommended gears in the link you posted are your best choice. The thread will be 16.6663 tpi. I didn't see the gear box settings but they should be III A. As always check the pitch with a light cut before threading. You should have 25 full threads in 1.5".

I approached the metric/English problem a bit differently. I installed a DRO so I can read the feed in both metric and English. I use the dial knowing that I am moving less distance than the dial indicates which is good.

You are undertaking an ambitious project. Good luck with it!

Just verified TPI=16

Thanks so much for help.....
 
After finishing my thread chase I've moved on to the slide bolt and completed the 16.667LH threads last night.

Next I will need to cover threads with something soft and turn down the other side. I've chosen and old 308 case and will cut end off and split down the length.

A PIECE of copper pipe may be better it's a little thicker . One slip and the brass case will be cut threads . Lead pipe is the best presses into the threads and grips tite. Just what I've found .
 
Brass cases did not work ........piece wouldn't run true, so I will try aluminum or copper. Shell cases are not same thickness all the way down....
 
well...I had success using 1/2 inch aluminum tubing from HD that I cut down the middle to cover the threads. To complete lead screw i needed to cut 8mm x 1.25 threads for dial on the other end.
You can see the aluminum tubing i used in one of the pics. Now on to the acetyl nut and boss.....
