    I don't have access to a blowtorch, and I don't trust myself well enough to cut into metal just yet. Like I said when Ocracoke suggested anyway, I plan on using the pulley as well.

    Did you try heating it with a lighter like NAT suggest ? You could try a risky way by cutting a slot out of the pulley

    It will work with one but you'll only have one direction of control. I guess you could try re-soldering the pad to the board (the pad looks to be just solder itself)

    So long as it is a signal pad as per the link Scottie posted, it is OK. It will influcence which channel is the forwards/backwards and which one is the side to side channel though.
