Cutting Foam Wings with a Hot Wire Powered by a Battery Charger

I use 19 gauge stainless steel wire. National N264-705 V2567

The foam is foamular 150 that I purchase from Home Depot or Lowes.

That is cool. Foamular 150 is okay..,kinda brittle though. I cover it with polyester monofilament 110 mesh(used on screen printing frames)held down by a thin layer of 5min epoxy. Makes it far stronger. Foamular 150 is also easy to hand cut; grate and sand. My hawk wings hand cut/sanded came out nice and were easy .

I run the 120v power source through a ceiling fan rheostat (variable speed celing fan control) to a receptacle (wall plug). I plug my 2 amp battery charger into the receptacle. Clamp the battery charger clamps to each end o the cutting wire. Control the wire heat with the ceiling fan rheostat.

Hi, CAn You please tell me haw do i made the power suply ?

I pre-cut the ends and the leading and trailing edges of the foam (my ends are parallel in most cases).  I visually place the cutting guide template (rib guide) centered on the end of the foam and all the way forward.

How do you know the rib guides on either side of the foam are properly aligned?
