Hey, guys. I am in the process of making a vacuum former, but I need a heat source. I can't use the same oven that I cook food in, nor do I want to buy a whole oven just for this project. I have looked at heaters, lights, etc, but I am not sure if they can melt plastic, or if they are sturdy enough for a vacuum former. Or they are in the hundreds in cost. What do you guys use for a heating element? Where could I buy a cheap, but effective, heat source? Thanks!
