Hello All,
although enough info is present n this thread but still want to share my share of info....

Hand held bow cutter may do some jobs but real work can be done only by a plate form cutter.
See the snap....with this not only the precision cutting is possible but you can give aerofoil shape to wings, make thin sheets out of thick sheets.... that too with amazing precision....

the snaps are self explanatory it all depends what cut you want adjust the wire & regulator.
 I have cut sheets upto 1mm thickness ( no jokes).

things are pretty much same as required for Bow cutter you need a platform and an iron L shape.

Nichrome wire is the best and use a SPRING to have tension on the wire. the wire tends to elongate when hot so spring keeps the wire straight for accurate cut.

Use fan regulator on full for cutting thick sheets and reduce as you reduce the thickness.

Tip -  always test on scrap thermacol  before you actually cut the real part to understand what speed you will cut and at which fan speed you get best results.
It can cut Coro sheet also...!!!

Have a look on this thread of what i could do with such a wire cutter.... @ #32

> choose high density thermacol for crafting, fevicol is the best adhesive i know to stick thermacol & PLY.
> A coating of 50:50 ratio ( water & Fevicol) with tissue paper on thermacol surface gives extra strength.
