I am curios, what would be the main reason to do that ?
yes that is my reasoning also on all three counts.My main reason is that when I started to make my own bands, I was copying Riffe.
Another reason is that it protects the knot in the whipping twine.
And one more is that it just looks so damn neat.
thats what i thought, but i figured i would check with you guys before i took a chance. incidently, it seems like there is rubber cement maybe on my riffe bands, under the shrink tubing? if so, do you use it?My heart gun has two settings, and the low heat seems to work just fine.

I was told by a local spearfishing shop owner here in hawaii that the smaller the knot the longer it will take for the bands to crack around it. He said he uses his truck to tie his wishbones. any thoughts on this?
That's what I do. Nice tutorial Bill. Interesting to see how you grind the ends. Was surprised that you just use a knot at the end; the RA Dyneema wishbones that I use have a nylon toggle at both ends, sort of conicle in shape. Other homemade wishbones I've seen use round beads. Your Dyneema looks considerably thicker than the RA ones -- so I'm thinking your guns have sharkfins rather than the smoothed-out grooves of the RA spears. I don't think dyneema that thick would work with my spear.I put a knot in each end to make it easier to grab, and then put one end in a vice and grab the other end ... wrap ...end around a screwdriver or pliers handle to get a better purchase and pull as hard as you can.

I like the idea of using superglue to lock the cinch knot. I usually smear the knot using a soldering iron but superglue would be less likely to weaken the knot. I notice one of the Italian speargun makers puts an extra half-hitch around the rubber after the cinch knot - which strikes me as a good idea, esp if you plan to melt/smear the knot.
Never used heat shrink on me bands but have on lots of other things and all I do it poor boiling water straight out of the kettle on it. Means you get an even temperature distribution and I doubt it'd affect the bands.
Nobody seemed to comment on this but surly it is the best way?
