Paul,
   The Eastwood company sells a hand crank Bead Roller, item no. 28060,
for beading sheet metal panels. I doubt that it would be strong enough
for tubing, but you might want to give them a call.  The pictures in my
hard copy catalog were pretty impressive, but unfortunately I left it at
work.  Here is a picture and price from their online catalog, if it
comes thru OK !

If this is what I used in metal shop many years ago the roller is way
too large to fit inside  1.25" ID tube.  Designed for sheet, as you say.

I think the beader has three small ballbearings in 120 deg radial drillings
in a rod that are forced outward by a inner threaded rod with a taper.  The
tool is twisted and the balls forced progressively outward. May or may
not have an external form to roll into.  Seems like I saw this somewhere
a LONG time ago and have at least half forgotten it.  I think I have told
you more than I know.
