 Note how the string is inserted on the capstans. The string can be attached to temporary anchor points to provide enough tension during this step. Inside `capstan_pulley`, you should insert a small bearing at the top and bottom. Use appropriate washers to have the correct height; there are 4 levels on `capstan_pulley`, and they should be aligned between each levels of `capstan_motor`.
