This will work:  install the expander and put a lot of pressure on it.  I'm
sure you have already done this.
Get out your ball peen hammer and start beating on the metal you wish to
streach.  Round and round you go,
Keep the pressure on the expander. Believe it or not the metal will streach,
just not as fast as you would like.
I've done this more than once, but don't like the time and energy
necessary.
Don't tell anyone as this is one of those things people will say Bull stuff!

Fly fast, land slow.

What you're doing is just expanding a very small section at a time as the metal tries to squish out from under the hammer blows.  So you're expanding the metal one little bit at a time.

Maybe you shouldn't give up on spinning quite yet, Rusty.  You have a lathe, don't you?  Or is it a mill?  I forget.  But try this.

Crank your expander in as tight as you can get it.  Chuck the expander in the lathe with the pipe stuck on the end of it.  Spread some grease on the pipe then wedge a bar about 4ft long against it as you run the lathe.  Move the bar back and forth until the pipe gets loose.  Stop the lathe, crank the expander tighter, and repeat.

Tell me if it works, and maybe I'll try it someday 8*)
