DIY Twin Motor RC Gearbox

This post is about the gearbox I am trying to make from salvage toy parts. Toys are super sources for parts. I salvaged the parts from a broken doll, 2 x 3v dc motors, 2 x pinions for 90 degree, 2 x compatible gears for 90 degree and two shaft gears, a rod, a hobby box. I use Vaseline for lubricating.

Shaft gears and shaft about to come.
