The barrel is turned down to 1/2 inch just run a 1/2-28 die on her and its done...

Bad idea. Have a gunsmith do it in a lathe.

They make a starter die that works good. not that big of a deal if the barrel is at 1/2 inch. I have access to a lathe so thats how I do mine..

Iron Ridge Arms in Longmont has done some for me in a few days. Total cost for cut, thread, & recrown was only $95

What method do you use to make sure the threads are perfectly concentric to the barrel? If not threaded perfectly, then you seriously risk a baffle strike and wasting all the money it cost you to obtain the suppressor.

Assuming the bore is exactly in the middle of the barrel...

I hope it works out for you.
