Cat 340D Excavator build

[crueby]

And another bit done this evening - made the pivots for the cylinder ends, and milled the opening for the first flex shaft (to move the stick). The motor has been mounted, ready for some wiring to test it all. Here is a view inside the boom:





and where the flex shaft comes out and connects to the cylinder end, to drive the leadscrew:





So, still need to wire up a ESC to the motor and hook up to a channel on the radio, and it will be ready for a trial run to see what kind of force it can put on the booms, and see how the travel time is. I've got some faster and slower gearmotors that I can switch to if needed to dial in the max speed and force on the cylinder. Hopefully it works well enough to continue on without having to change the leadscrew out.
