[TowerTalk] How bend aluminum tubing

[RICHARD L OWENS]

Steve
You didn't give the radius of the bend.  This may be very important, as
you can bend it only so around so short a radius.  An old standby is a
common door spring.  (I say "common" without knowing if they are even
sold anymore in hardware stores.)  Cut the end loops off--the ones used
to attach it to the door and the jamb-- and slip it over the element. 
With the element being 1/2 inch, you may have to slip it inside the
element.  This should keep the aluminum from collapsing as you bend it
around a jig the shape you want it to assume.  The jig can be a 1/2 or
3/4 inch piece  of plywood fastened to a larger piece of plywood.  Keep
an eye on the element as you pull it around the jig.
