Write your reply.

assistant: This I've tried, and have had less than glowing results.  Even went
so far as to buy a thread die and tried to use it... seems the
aluminum outer shield is too soft and easily fouls the threads of
both the adapter and the die as well.  Still working on getting
things to work though.. haven't (completely) given up yet.
Thanks Bill.
