Cal, my only input is to make sure that the wire element is looped and
connected to the extremeties - one of the guys here had a lapped solder
joint on his and it let loose and the front came flying at him.
Fortunately he was using smaller rubber so it only smarted a bit but
winding hard like you're talking about, if the front end came loose it
could do some serious damage.
