We had our winch driven arm tested in our garage last night. Today, it ended up with the motor wired up to the Spike in the wrong direction. The resultant 400 ftlb of torque turned both of the two #10 stainless steel screws pinning the home-made hubs on the pulley and the arm to the shaft into "subtle s-shapes" that had to be drilled out to get it all apart to be repaired. The other team members were amazed that the 3mm diameter Dyneema cord held up to this abuse. Its breaking strength is rated at something like 1950 pounds. We will rebuild it tomorrow with bigger bolts and a better hub design, if possible.
