I missed the original post for this. I have a draw plate used for
making musical instrument. Are you looking for a "one-time"
application for this draw plate, or a permanent solution to making
tubing like this? If you only need it temporarily, I could be induced
to let you borrow mine, but I am not willing to part with it. I do
use mine, but could part with it for a week. I also have a set of
barrel-shaped blocks, used to remove dents in instruments, and a set
of flared stakes with a press, used to form the bell mouth. I don't
use these as often as the draw plate, but I do get an occasional
request for a repair like this. I bought a shop from a guy who
retired, and used to repair musical instruments. A lot of odd stuff
in that lot.
Call me if I can help. Doug
