Building A 52 INCH Robot With Arm

Making The Reel

Using a 2" circler hole blade, cut a hole in a 1/2" thick piece of wood. Take out the wood from the blade. This will become part of a reel. Make another one. Clamp the two wheels together. Drill four pilot holes around the wheels. Unclamp the wheels and make the four pilot holes in one wheel .140" big so that the 2" # 6 drywall screw can fit thru the hole. Open up and square out the wheel's center holes so that they can fit on the motor's square shaft. Using the four 2" # 6 drywall screws, screw the two wheels together so that there is a 13/16" gap between the two wheels. Tie a 54" long monofilament (weed eater trimmer line) line to one of the screws.
