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 :)
