Yes I did use a lathe to trim all the parts and make the new shafts. I used a small square file
to cut flats on the new shafts for the set screws of the small pinion gears ( much less work and less costly than
using my mill ). I also used a drill press to drill the pin holes through the gear hub and shafts. I used small ( very small) steel brads for pins.

I'll try to put up a small video assuming it doesn't rain on my running area before I get to it.

I was quite cross at first with the cramped (gearbox) internals but as it turned out well I'm pleased. I'm hoping to finish the wiring and upper hull mods over the next few days. I'm not wild about the switch hole on the back of the lower hull as it looks pretty wonky but as it is there I'll leave it and it is a convenient way to power up the model.
As I'm not interested in smokers and bb guns I've left those out or in the case of the gun - disabled it basically it's a dumb bar now, the sole purpose of which is to engage the main gun elevation...
