I know a lot of you aren't interested in my continuing modification of Zelda, my APQS Ult 2 longarm system, but for the few that are, I want to share my latest upgrade.
For the last four years, I've been turning Zelda's rollers by gripping the roller itself, and turning it. The rollers are about 1.5 inches in diameter, and don't give you a lot of leverage (Zelda's rollers turn very easily because of the ball bearing pillow blocks they're mounted in) to move the machine and the quilt back and forth, and with the take up and backing rollers unlatched, they want to unroll all by themselves.
