Onto the cowl, my favourite part of any aircraft, they are so individual and have lots of lovely fixings, bumps, air scoops and other odd appendages to stretch our modelling imaginations.
First a photo of the finished article, it can appear a daunting task but taken step at a time it’s OK.
A decision has to be made as to whether to cut non-scale holes or use scale inspection hatches to gain access to the engine for choking and adjusting the needle valve etc. In this case the sides are hinged so the choice is fairly obvious although it does complicate the build somewhat. The first step is to make ply formers for the front and rear, with this cowl it was slightly more complex, because of the hinges there are actually 3 formers, top and left and right sides, for both front and rear. The formers are then joined with balsa “longerons” and covered with 1/16th balsa. Wetting the outer surfaces where there are tight bends helps considerably.
The next problem is the long hinge. Commercial “piano” hinges are just too big and won’t bend. You can make your own quite simply by soldering brass tube to brass strip and cutting into suitable lengths.
The hinges are glued using epoxy.
The result is a very neat joint.
That’s enough for today, next time it’s fixings, louvers and exhaust pipe.
