John brings up a very good point. Normally aluminum wire is run from
a spool gun or a push pull gun. You can run aluminum thru a push gun
if (a) you are lucky, (b) the gun cable is short - 10 feet of less, (c) you
have a teflon liner, (d) you are using 3/64 or larger wire, (e) you have
the correct feed rollers for aluminum and (f) 5356 or other suitably stiff
aluminum wire.

Note that I am not saying you can not push aluminum without (a) thru
(f) but the less of (b) thru (f) you have the more (a) you will need. I get
away without (b) and run it thru a 15 foot cable, but I am very careful
to make sure it is as straight as possible and I have (c) thru (f) in place
and it appears as though I also have some (a).

Otherwise you will discover what the term "birds nest" means.
