There was a post over at MOS by Stillwantmore, I think about using a thin cord as a constrictor.
Chosendudenyc,
You can buy releasable cable ties, or easily mod a normal one, search Thunder’s for a post on “boa-constrictor”, a commercial version guys here were duplicating. It’s easy, you just cut away about 2/3 of the rear of the upper housing with a sharp utility knife, enough to allow you to lift the tail away from the teeth.
