Instead of a " + " shape for the carbon fiber backbone, what about an " X " shape? That way, the rail or track can be housed in wood, and need not be integral to the CF backbone. I would have to do the math, but I don't think you will sacrifice significant strength. And most of the things that go into a gun are installed on the centerline (trigger mech, handle, line anchor, etc.), so it might be easier if there wasn't a vertical CF member.
. . . Unless you just want it that way.
Az, I have a cunning plan - I hope to set a waxed 8mm polished stainless rod (a spear) into the mould to act as a rail.
. . . i was thinking of putting a delrin rod, pouring the mold, then cutting a track in the rod . . .
Don its funny how guns vary from continent to continent for basically the same species, double 16mm rubbered railgun account for probably 70% of the australian market, and these in 1.3m and 1.4m barrel lengths throwing 1.8m to 1.9m spears account for more Mackerel, Wahoo, Mulloway (you white seabass) than anything else with fish sizing ranging from as small as 1-2kg through to large wahoo mackeral and Mulloway well over 30-40kg.

I agree with you, I only used 4 bands when I was stalking very large Black Marlin. I dive a spot 100 miles off shore that can have record sized fish.
I normally hunt blue water with 3 bands cocked on my top shaft and 1 band on my bottom shaft.
A lot of the 25 to 40lb fish I try to head shoot with my small lower shaft.
I just mentioned my gun to illustrate that Mil spec 7075 1 inch square tube
can be made very stiff with the addition of bonded wood exterior skin.
Cheers, Don
you devil, perfect idea, make sure the rod is nice and straight :martialAz, I have a cunning plan - I hope to set a waxed 8mm polished stainless rod (a spear) into the mould to act as a rail.
could i see pics of that gun? i want to make a 2 shot gun. i got a trigger from josh to make 1 i just cant decide on the size of each spear.
