Sorry it’s been so long since the last post! Life does tend to get busy.
After pricing hot-wire styrofoam cutting knives, it dawned on me that I have 3 or 4 old Weller soldering guns lying around here that’d probably do the same thing. So I bent a piece of 12 ga bare copper into a sort of knife shape, and it works even better than I could’ve imagined!
This is THE way to cut styro, with none of those leftover ‘crumbs’ to vac up when you’re done! I use an old rectangular stone pizza board and 24” aluminum ruler to cut pieces off straight. Works great, without spending the $50 they want for a frail little hot knife. Just try to use it where there’s some ventilation, bc the fumes aren’t too healthy if you’re cutting a lot of the stuff. It’d be simple to make different shaped ‘knives’ for the Weller to cut odd curves, rounds, etc. The Wellers I have here use 7/16″-14 nuts to hold the copper tips, and I’m sure they could be made from setscrews without much trouble if extra nuts can’t be located.
‘Really need to experiment further with this one.
God bless,
