"I think" it'll work well with Aluminum too, but I make no gurantees and I'm
not running out to the shop to read the lable as it's pouring rain as in
visibility no more than a couple hundred yards. Forecase was for light
scattered showeres.

You mean this approach may not work with those two sections I drove
together? <g> Brand new too. It was part of an antenna boom. They sent me
new parts within two days. It'd be nice to save them and they've lain up on
top of the shelving out in the shop for years. I'll probably end up using a
small rotary saw or cutter in a mill to slot the outter tube enough to get
them apart. That'll save the inner one and still leave me with about 6 feet
of the larger stuff (that's out of spec)
