Thanks very much Gerry, and I'm glad it helps.
Got some more done to the wing today, with the radiator detailed and the radiator bath prepared. The landing lamps have been made and fitted, and the scalpel blade cover cut to make the lamp covers. The wing-tip navigation lamps are part done too.
PIC 1. Shows the simple detail added to the radiator matrix, on both sides, using stretched sprue and slivers of plastic tube.
PIC 2. Work underway on the radiator bath, with some ugly ejector pins more or less removed, the shutter opening cut out and the walls thinned to a more scale appearance. The intake support stay has also been added from stretched sprue. A new shutter will be made from plastic card, and the internal support stays and shutter actuators made and fitted once the bath is in place.
PIC 3. The landing lamps were made from lengths of plastic tube and rod, painted with a chrome paint pen, and glazed with Micro Kristal Klear, which is in the process of drying (and clearing!) in this shot. The lamp covers, cut from the scalpel blade cover, will be fitted and sanded to blend-in with the wing, and then polished. They are a bit thick, but better than using 'solid' clear sprue, and certainly better than no lamps at all !
PIC 4. Scraps of clear sprue have been super glued onto the wing-tips, after first drilling holes on the inner face, which were filled with the appropriate coloured paint to represent the bulbs. Once fully hardened, these will be filed and sanded to shape, and then polished.
After around ten hours work on the wing, I feel I need a change of scene, so this will be set aside for now, and work will start on measuring up for the complex tubular frame work for the cockpit, and constructing the rear bulkhead, seat, instrument panel and other bits and pieces.
Thanks once again for your interest and kind comments, and I'll post another up-date soon.
