Stephen, many thanks for your kind comments.
Building new hulls meant I have to make holes for the side transmissions and the easiest way was to make a small peg on the drive wheel axle (this was later removed), see arrow;
I had marked out the center of the drive wheels when drawing the lower hull sides so this work was quite easy but time consuming. I´ve also had help from Stefan Konitzer again with lathing two alu rings (I couldn´t find large enough material myself) and milled and filed these into place.
I´ve decided to use Armortek´s side transmission as it would mean too much of work to change this and drive wheel as well. The side transmission cover itself can, with some changes, be made to look a little closer to the original. The first step is to mill away some material to be replace by laser cut part;
Two small fixtures (see arrows) were made to hold the piece in place while drilling the holes for the new screws;
I also drilled holes for the Allen screws on the inside of the lower front hull;
The rest of the work was concentrating on detailing the side transmission which meant adding some new bolts, filing and adding putty (A);
More details were added and A is for screwing in a lifting eye when removing this part in reality and B is an oil drain plug;
I finished this work with doing a new rubber gasket;
Cheers Per
