Making your own tube for a secondary form is a very viable option. I have 
made large diameter plexiglass tubes like 2 feet in diameter by heating a 
1/4 inch thick sheet and then bending it into tube shape and then joining 
the seam with methylene chloride. It's sure a lot cheaper buying the sheet 
than an already formed tube! It's a shame it can't practicaly be done with 
very low loss material like polyethylene or teflon, but damn near nothing 
will work as an adhesive for these!
