New gun - shaft/wishbone question

    I just received my new gun a couple of days ago. I was supposed to get shark fin tabbed shafts, but instead got pinned RA shafts, which require a thinner wishbone. At this point I don't have time to swap them out before I leave for my trip, so I'll have to use them.


    The wishbone cords on the bands on the gun are doubled up, as you can see in the pic below, which doesn't seem to work well with these pins. I haven't tried loading the gun yet, but I can tell that I would be able to get one cord on the tab. But it looks like both cords would be tricky, as one cord would either sit behind the other, as opposed to being on the pin, or would get poked by the pin, if you know what I mean. Do you think this will be an issue? It looks like this would work better with a single cord, but I'm guessing it'll be tricky to try to make sure only one cord is sitting in the tab, with the other free.


    I've tried contacting the distributor about it, but haven't heard back. Any advice would be appreciated.

    I don't see a point to the double wishbone. You always want to be checking the condition of the wishbone anyways not relying on the second wishbone being there for you if the first one fails. If this was mine the first thing I would do is change the wishbone to a single Dyneema. Also hese inserts make it very easy to change the Dyneema when necessary.


    Lack of finishing touches on that gun BTW. I would use black twine to tie the bands and taper the ends. A gun wouldn't leave my place the way it is in your pic.

    So is the point of this setup to only use one wishbone cord, with the other free in case one fails?

    The hydrodynamic drag is doubled, one guy told the double loop put less hurt on his fingers
    when loading. :rolleyes1: I told him to get a grip;) Dan, may disagree with me but I like to have the band
    taper at the end to further reduce cavitation/drag. These factors are much more important on a single band gun when looking for maximum efficiency with out piling on more rubber.

    I don't disagree Don, I commented on the lack of taper in my previous post.


    Your right....I was speed reading far too fast..:D My pupils have those loooooong...tapers.:D

    I guess I'm changing the setup before I leave, or once I get there. This will be my first time doing this, so it should be interesting. Thanks for the advice. And thanks, Dan for shipping the stuff to me quickly.

    You are supposed to use only one of the wishbone cords, the second one is a spare but like Dan said you are supposed to be checking your wishbones. My Kanji came like that and it was the first thing I changed.

    That's what I was wondering. I haven't tried loading it, but just from playing around with it, it looks like the "free" wishbone would probably get hung up on the pin a lot, which might damage it. Yep, I'll be changing it. Thanks.

    Is that a "new" gun or just new to you ? That's not how aimrites are normaly shipped . They have black mono and the the bands are tapered with replaceabe center wishbones

    I bought the gun and a bunch of other stuff from Neptonic.


    That makes sense that was one of the 4-5 that were. Mailed over that Josh sent out while he was waiting for his stock to arive via freight one of his guys must have rigged that one

    I won't touch it. Don't fix it if ain't broken.


    Regarding the wishbones, try to load them as they are, without paying too much attention to them. I think they should work. These double wishbones are a solution to prevent loosing a day out speafishing due to a broken wishbone.


    Then, WHEN IS TIME TO CHANGE THEM, you can replace them by single ones with "fast rigging devices" like the ones Dan offers or with a loop like this:






    Dan product is great and easy to use/rig and probably has other advantages like preventing the water to enter into the bands hole, but the loop is enough for me and works fine. I have a reel of 2 mm dyneema from RA and can change the wishbone cord even into the water. I always have a little piece of cord tied to my floatline. I had to change it once and all I had to do was taking off my gloves and tie a new wishbone. 5 minutes! :)


    When I rig my bands, I taper the ends. But I don't change/modify the original ones until they need to be replaced. Actually, I can't tell the difference. But tappered they look nicer. ;)


    I'm now using 50 lb nylon to tie them (Dapiran uses it) and has worked well so far. I ran out of twine and had to tie my bands for a trip the night before going out... :rolleyes1:

    I'm not sure I understand exactly what this means. Can you clarify? Thanks.


    Marco - that looks interesting. I think I've seen it somewhere before, but I don't remember where. What knot are you using to make that loop, and what knot are you using to tie the wishbone to the loop? Thanks.
