Thermo Formed Depron Wings The article was "Portugeuse Tiger Moth", about a 1/20th scale Tiger Moth but this dodge for forming Depron was worth repeating on its own. Taken, with thanks, from the August 2011 edition of RC Micro World - a .pdf publication available on line and as a subscription from the USA.

The Depron pieces are fixed to the jig using a few bits of sticking tape, followed by a gauze bandage. I use a bandage, as the hot water does not affect it, and it does not mark the surface. The best part is that one can mould 6mm wings this way, something that is nearly impossible with a heat gun. In fact, the picture above is of a 6mm one (a 1/10 Bristol Scout lies somewhere in future but the technique is the same for the 3mm one.
Then, rotate the cylinder so the Depron piece lies in the hot water that has accumulated in the bottom of the bathtub, and let it cool there. When the water is lukewarm, it is time to take it away and the panels are ready for use. The 6mm ones might need a second dose of the hot water 'treatment'. Arnaldo Correia |
