RE: what wire for my hot wire foam cutter?
John:
You can easilier get the safety wire at old fashioned auto supply places. It can also be found at the places which do gasoline engine rebuilding. Those biggie places listed with the splashy advertisements seldome stock the stuff. I used to get it for about 50 cents, which is less than postage now.
Not everyone has an airport or aircraft engine rebuilding place local to them.
