I tried glass beads once because, all the sand I had was too wet. It worked ok.
Although I've never tried it, the director of engineering at a place that I spent most of my working life at, told me that you can also use Cerrobend (SP). It's an alloy with a low melting temperature that you can pour into the area to be bent, filling the space. You make your bends and then, melt it back out when you're done. The stuff has other uses as well. I think I priced the stuff once and it wasn't exactly cheap but, you can use it over and over.
I also remember seeing a trick in Popular Mechanics once, where you insert a close fitting, wooden dowel into the area being bent. The dowel had a series of saw cuts spaced about 1/2" apart and almost through. The tubing being bent was around 3/4" dia. The dowel stays in after the bend so, don't go welding in the bend area.
