foam cutting - tougher than it looks!
Well I ruined my first blank last night, and the first of many I am sure. I am trying to do it freehand with formica templates and the core came out all wavey.
My problems it seems:
Not enough tension in the wire as it drags badly - the ends of the wire come out of the foam at least 30 seconds to a minute before the middle makes it out.
Not enough heat as it takes quite a bit of pressure to drag the wire through the foam. I was trying to keep the temp low enough so that it took 2 minutes or more to go through a 7 inch chord wing but I was really having to pull the wire through.
So I'll try fixing these things tonight and see if it comes out any better. At least the power supply that you guys helped me build works like a charm!!!!
