A friend of mine tried to make his own curving machine, using
a length of steel pipe and a propane torch. We had great fun
watching as he burned his fingers and leaped about yelling
"Ouch ! Ouch !" and made all manner of wavy plastic, but it did
get a bit scary when he almost set his shop afire.
See ya, Dave

Dave,
Here is what I do.I buy the 7 mil sheets (I figure it provides less
friction than the 10 mil) and roll it up inside of a peice of carpet
roll tube.Then I bake it at about 160 in the oven for 30 minutes.Then
cut it into strips and use scotch 665 double sided tape to adhear it to
the wings and 3M 850 mylar tape for the safety strip.I can do top and
bottom of my flaps ailerons and tail a couple times over for about 50
bucks.I replace it every 3 to 5 years and I have never had a
problem.This does seem a little less entertaning than your buddys
method, but it works fine.
