Work has begun on the left side of the interior, I made one throttle lever and knob assembly. Now that I have the manufacturing sequence down, the second one is easy. The level is formed round on the end and threaded for 4-40, the knob screws on. Also shown is the plug that will used to make the carb heat control box. I tried to vacuum form the part with little success, rather than mess around I plan the simply make a fiberglass part since the plug was already made up. The plug is treated with PVA, once dry I'll put the glass to it.
Very soon I need to decide if the sides will be covered with aluminum or stay with my original plan of glassing the sides to simulate aluminum, I'm leaning towards glassing.
Another neat thing a found at the craft store while trying to find beads that work for throttle knobs is the porportional scale, set it at your percent of scale just read the reduced size, no more dividing by 3, works on all scales, I recommend it to anyone doing a scale project. The search for beads was unsuccessful, so I made the knob on the lathe.
