Abstract: A multi-piece spool includes a first spool piece and a second spool piece. The first spool piece is configured to receive a first axle. The second spool piece is configured to receive a second axle. The first spool piece is configured to attach to the second spool piece where the first spool piece and the second spool piece are rotationally affixed about a longitudinal axis created through the first axle and the second axle. Wherein, the multi-piece spool is configured for locking the first axle with the second axle for rotating the first axle and the second axle together when the first spool piece is attached to the second spool piece.
