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
