RE: BVM Mig 15 build
Still waiting on the harware, so have tackled a few bits and pieces.
Still strengthening the wing landing gear area after reading some more build threads, but cannot do the final work until the gear is here, will add cf thin plate to spar webbing as the balsa seems to crack on heavy landings which results in the wing twisting resulting in the top skin splitting. Once the landing gear is in and checked I will also apply cf to the inside of the wing skin in the landing gear areas.
With the decision to add some lighting (nav & landing) to the model I needed to fabricate a clear cover for the front inlet duct landing light. A mould made from two layers of cf cloth and some 5 minute epoxy, after some work finishing, the surface was ready to cast the plug. The mould was pva release coated, and waxed with a couple of coats of ordinary furniture wax. A mix of 15 minute epoxy was poured in and the resulting mixture created a working plug.
With a little stopper sanded back my local model shop will vac bag some medium weight clear sheeted casts from this tomorrow.
I have also added some extra cf to the front landing gear areas, as this area is always subjected to large stresses and strains.
Until later...
