Nice work.

I made a secondary form 7" in dia. by 19" high by bending a heated 
sheet of flat 1/8" plexiglas, but what a nightmare.  Parts of the plexiglas
got too hot and started to shrink, and it was hard to get the seam to
bend enough.  I had to finish the job with a propane torch.  Eventually
the job got done and produced a useable, but not perfect form.  

I'm sure with the proper equipment and experience, it can be done 
better and more easily, but I think I'll look for pre-formed forms in the
future    :)
