Make a Hot Knife using a soldering iron
Great idea! I had an old soldering iron (30W) with a copper tip laying around, I've followed your instructions and this hot knife works like a charm. I've only made a slight modification: I've cut the bottom part of the blade in order to maximize the surface area with the tip in order to get better heat exchange. Thanks!
Thanks for the idea! I've just made a solder dispenser using this concept, gluing a wide screw as an axis for extra stability.
