homemade plexi strip heater

[SXRguyinMA]

alright I need to bend some plexi for Rockin Case and I've seen all the plexi strip heaters, etc. Now, I can get my hands on some cheap snowmobile handwarmer elements of various sizes for a good price, and I'm thinking of using those to heat the plexi, then forming it in the wooden mold I'm going to make. I'm working now on findng out the temps these things get to, they have a lo and hi setting as well. heres an example of one I can get:

the other is similar in construction, but about 1/2" wide by about 12-13" long. They've got sticky tape on their backsides, as they're designed to stick to steel handlebars.

I could stick them to a thin vynil sheet, like a transparency sheet for inkjet printers or something, and witer them up in parallel to a spare car battery. Anyone think this could work?

honestly, I doubt they will get hot enough to melt the pexi. I don't know for sure.

they get hot enough to physically burn your hands if you dont have gloves on

[ShadowNyfe]

definitely interested in this experiment of yours :O I need to bend some plexi too and I have no idea where I can get someone to do it for me haha

Well, if they'll burn (actually burn) your hands, they should at least soften the plexi. Certainly worth looking into.

You will need a heatgun that is atleast 1000watts to bend plexi.

any idea of the temp plexi needs to be to soften? I'm going to fire up a sled here at work and turn the heaters on high then check the temps

youll need a 1000 watt heatgun to bend plexi, those heatpads run at 12V, that would draw about 83 amperes, you would need a cable that is as thick as your leg is.. this wont work for sure

car audio (4 gauge) would work just fine

You know if you just use the 4 gauge wire hooked directly to 3 car batteries, you could probably just use that to heat and bend the plexi.
