Hi, I'm working on the form for my 1/4" refigerator tubing primary.
I'm planning on using 1/4" polycarb for the support fins. I've got the
calculations made on where to notch the plasitc in order to create a
nice uniform 30degree slope and 15 degree rise with 1/4" spacing
between turns, but what I don't have is, what can i do for holding the
tubing into the notches? I don't want to just let it lay there, do I?
I'm not so sure that adehesive is a good idea, is it? How is holding the
tubing into the plastic commonly done?
Thanks, Walt Kulpa

Walt,
I tied my copper tubing in place at each notch with waxed lacing cord. Let me
see, I had 8 supports times 14 turns, that's 112 spot ties. No wonder I had
cuts in most of my fingers. Small nylon tie straps would be much easier.
