Three bands on two-band muzzle

[bboynaki]

Hi I am thinking about putting three bands on a two-band muzzle. How can I do this? The speargun I have is Bucanero 126 (has a stretch of 140cm) which has a muzzle like Rob Allen with two holes for two bands so three will not fit. I have 7mm*170cm spear and I want to use 3*14.5mm rubbers. How can I add the third rubber?

It is actually very simple but tricky to explain !
You can attach 2 rubbers to one hole, the second rubber needs to be attached with a string. When you remove it, it looks like it has 2 dynema wishbones one from the front, that you can attach to the muzzle and your usual wishbone. I hope this makes sense.
I tried to find a picture, so its easier to understand ! But all i found was this video !
If you watch carefully, after he fires you see how the rubber is attached, his gun only has 1 hole for one band (its the old version of the sk40)

Thanks, I have heard about this. Any special way to tie the wishbone that loops around the hole? I'm guessing no metal inserts, just stick the dyneema cord into the rubber itself right?

Yes but you will need a nice knot so that the cord doesnt slip out ! Jus tie it as you would a normal wishbone i guess ! I have never tried this before, but i cant think of any complications with a normal wishbone !
