Thanks landyacht!
Yeah, that sounds like it takes too much muscle for me. After all, my hands would have to transmit the arm strength. Unless I can sit on the thing or something -- my mom once had a tubby cat who won all fights that way :).
As for my soldering skill -- I am terrible! The tendonitis impinges on my nerves, so I am not super coordinated for fine motor skills. But the cable I did the other day has been holding up to a bunch of flexing and pulling, so maybe I am getting less bad. Or maybe it's easier with bigger parts.
