Re: Light tuna gun

Shaft whip will not be a problem with 8mm rod and 4 x 5/8" bands unless the rod is really soft metal. If it is spring stainless steel or the new super stiff carbon coated shafts. I would have preferred a 7.5mm shaft with 3 stiff bands for 20kg to 30kg fish. You might even be able to get away with a 7.1mm shaft if you enclose part of the track. I like you idea of "whip inhibitor" but really you only need to do it 20cm or 30cm near the trigger part to theoretically shorten the shaft whip profile. If you do it in sections, chances are that the fins are going to hit them. For a light gun a 7.1mm will have much less recoil, and 3 bands will really give that shaft a lot of velocity that will keep the shaft shooting flat. In open water it is hard to judge distance, and if you are taking long shots, a fast velocity shaft with little shaft drop is really nice.

By the way the gun looks really nice and would be great to get some more detailed close up photos.
