~1:12 Miller Century M100 Rotator wrecker

[dremu]

One thing I discovered is that on many rotators, the crane doesn't just rotate, it slides. Yep, in addition to rotate, lift and extend, the dang moves about a third of the length of the truck. Makes sense, but it's a mess to engineer. You can sorta see the pistons of the actuators for that behind the top aluminum. As with the outriggers and crane, it's telescoping because there isn't enough room to fit a single stupidly long actuator. The rearmost one pushes or pulls a middle slider (here, white with a little blue toolbox thing, which later changed to black with no toolbox), which then chains to a second one which pushes/pulls the transom proper.



So it slides on aluminum angle, above the frame, marked "L." Here I'm working on wire management, because there are So. Many. Freaking. Wires in this build. If I never crimp another Dupont connector until the day I die it will be too soon. But I wanted it tidy and did eventually get it so. Hard to see, but above and to the left of the actuator for the tag axle is a black U-shaped thing. The 3D printers and CNC machines use it, call it "drag chain". Allows a wiring bundle or tubing or whatever to move in one dimension (this case, fore and aft) without moving in others (sideways or vertically.)

Eventually got the wiring mess tamed
