Al u-bends

[Dan Elsberg]

We got tired of the high prices and low availability of Aluminum u-bends so
we made a mandril bender.  It was a _lot_ of work.  (about a week of
machining and then another couple of days playing around with the
technique.)  Anyway if anyone needs 1-3/8"x0.058 we may be able to work
something out that would be a lot cheaper than the estimates we got from
various other sources (one wanted $275 to bend 6 semi-circles (180 degrees)
including the labor and material).  E-mail me directly if you want to talk
about it.

If anyone wants a description of the tool we made e-mail me about that too.
