I'm going to make a fuselage part plug - it isn't a whole fuselage, just
a round-to-flat conical transition part that will be glued into the
round part of a finished fuselage in the nose cone region. This will
probably be a male mold; I don't think making a male master followed by
a female mold is required.
What is the best wood to use for plug making? I have searched through
my RCSE archive (about 2 years worth), and I have found references to
poplar and basswood. In the past I have used oak and douglas fir, but
my past experiences were for much larger parts (not R/C related
projects). I have also found many references to finishing techniques
including using epoxy resin, filling auto primer, auto body filler
(bondo), and lacquer.
One post from Joedy Drulia suggested that poplar could be sanded down to
400 grit and waxed without need of paint or resin. I like this idea -
it is quick, simple, and there would be no way for any paint or filler
to pull off the plug when the part is removed. If you did this, but
included filling the grain, I would think you could get pretty good
results. Anybody else try this method?
