That self-amalgamating tape's a good idea Stu... I pulled the tie-wraps tight and cut the ends down very neatly so there are no sharp ends at the moment, but I'm sure that if someone grips tightly, then the plastic ratchet mechanism could tighten and expose the sharp end. Hmmm, or just "weld" them up with a soldering iron... did you ever sell that consignement?
