Gadget,
Thats a real "cool" hot wire cutter. Great job!
What kind of voltages and transformer are you using?

That would be really useful for lost-foam casting. No room in the shop for a new station, though. Good post.
Gadget, thanks for the post and build information. I may borrow your idea if you don't mind. I have been planning to put a hand wash sink in the garage/shop but need to insulate it for protection from freeze during the winter since the garage is not heated. I had planned to use the foam insulation board and a strip heater for the sink and enclosure. Original thought was to cut the foam with a bandsaw or sawzall but the wire would be cleaner.
Thanks,
Benny
If you have a rheostat or router speed controller you can plug the charger in that and have a way to reduce the voltage. You could probably use the 12V charge side with the rheostat on the AC side and get the voltage just where you need it.
