For no other reason than I have sheets of styrene and a 3D printer, I have decided to have a go at scratch building a Comet A34. Despite the box shape, it will be neither easy or quick, so don't expect rapid progress, quite apart from which I am clean out of printer filament, and need new nozzles from Australia.
I have cut out the hull side panels so that's one job done, and have another piece done for the hull base. A test fit of HL gearboxes miraculously allows them to be bolted to the hull floor and the shafts will line up with where the sprockets should be.
The road wheels are my current challenge. I could use Bulldog/Pershing/Leopard wheels, but they are 800mm on the real thing, which makes them the same size as Tiger roadwheels, so quite a bit bigger. I am currently trying to design wheels as one piece two wheel setups, with recesses for bolt heads and a roller bearing. If I could find a way to obtain rubber rims that would fit that would be the icing on the cake, maybe Tamiya Tiger ones might fit? If that doesn't work, the cheap and cheerful option might be to get hold of Tiger wheels and print inserts to turn them into the Comet design. I could then use Tiger suspension arms and save the hassle of printing those.
A couple of pics, ignore the print quality, I am using up the dregs of some old filament that is never going to give me a good finish in a million years.
