It's built from:
AM-0145 Toughbox
AM-0396 long hex output shaft, cut down a bit
2 - AM-0069a 500 Hex hub, modded with set screws. One hub is also modded with teeth
2" of aluminum tube - 1.75" OD
Mini Cim
HS-422 servo
#10 threaded rod
3/4" x 1/2" aluminum bar as spacer for dog (has F <-> B in photo)
3/4" x .125" aluminum bar for dog
.090 servo support plate (sits between bar and the gearbox, holds the servo in position)
small qty of .090 polycarbonate to make dog actuator for servo
2 longer bolts (I think they're 1/4x20) for fastening spacer bar and plate to gearbox
#10 machine screw with washer for pivot. The spacer is tapped to accept the screw and there's one washer on the other side.
spring (random hardware store spring)
smaller machine screws (#6?) to fasten servo to servo support plate
It's probably 3-4 hours of work all together.
One key to longevity is to keep the dog from riding on the modded hex hub when the winch is operating. When we operate the winch in the lowering mode, we slightly raise it first before actuating the servo, so that the dog does not bind.
The only concern we have is that the winch is supported on only one side. We're bringing another gearbox plate and necessary hardware to make a support for the other side if that turns out to be a problem.
