Aww, thanks Sam! I guess I just needed to have been a bit more brave with interpreting my diagram. Still having a bit of a nightmare with the shaft to get the bearings onto and I still need to figure out how to connect the gears to the shafts securely.

I've got some rear metal plates to go on the robot and working on getting the front plate made up along with a new Scythe-Axe. Bit of a long saga with them but my aim is to now have something battle ready by 2021.
