"Bending materials with a simple hot wire forming tool"
CoryBee:
Thought some of you acrylic benders out there would like this read.

That's pretty awesome. I'd be actually thinking recently about how to go about doing more precise bends with acrylic than can be had using a heat gun.
Thanks for posting this!
Howard_Casto:
My problem was never with the bends, it was getting the plastic/acrylic/whatever at just the right temperature.
RandyT:
That's a good write up. The spring is very important (as I found when trying this on my own a long time ago) and you can also use an old timey heavy duty battery charger, instead of a battery. You want to be careful not to get polycarbonate hot enough to smoke when trying to bend it. The fumes are pretty toxic.
ChadTower:
What does the spring do?
