We buy from Laird Plastics - http://www.lairdplastics.com/ It looks like you have a local distributor in Houston. It was 1/8" thick and textured on one side (not that that is important). My invoice calls out p/n: 176372, but I am not finding it on thier site at the moment. Your best bet is to callor stop in and ask for 1/8" ABS sheet; it is not a complicated purchase. I picked up a 48" x 96" sheet for ~$40.

Happy enough to do it again. I don't recall it being difficult to get uniform heat; we just kept the gun moving. The free portion of the sheet was left hanging off the desk, so it was very clear when it was ready to bend and overheating was not an issue. If we do it again I will get a second gun to speed up the process.

I have used those strip heaters before and they work great when your part can accomodate the size of the heater. I can see cases in our design for last year where it would have been tough to get a strip heater into where we needed to bend. That may just be me not thinking about it hard enough though.
