Do you have a hacksaw? You can make your own by taking a block of aluminum of the right size and applying elbow grease (via hacksaw) to get the shape you need. You could also build them from wood, or use more advanced machines like a bandsaw or mill if you were to have those available.

... or cast your own. This stuff is super easy to use and quite tough when fully cured.

Generally speaking, a window motor is probably going to be underpowered for a large arm*. At the same time, FP have a nasty tendency to burn up if you stall them, so you have to be careful with your arm design and transmission choices to avoid stalling a FP motor.




*Yes, I realize balancing can reduce the load on a motor.
