Re: Carbon Fiber Gun structures

C4 thought that they were being clever by making a front end that combined a band anchor hole and band elevators into a new design where the power bands were trapped by side struts paired on either...

Re: Carbon Fiber Gun structures

C4 also make bicycles like this one from a few years ago. Bring plenty of money!
P.S. Looks like they are no longer making bicycles and are now solely into dive gear. The yellow bike is their...

Re: Carbon Fiber Gun structures

It is possible to hang a set of line wrap pins out the front end of the gun, but they need to hold the shaft onto the track as can be seen here on one of Kosta's (Seal) guns....

Re: Carbon Fiber Gun structures

The "Urukay" could be modified by adding line wrap hooks on the forward mounting screws where now there are nylon spacers and shooting line routing rings. Another hook could depend from underneath...

Re: Carbon Fiber Gun structures

The new "Gladius" has addressed this problem by providing some conventional line wrapping hooks. The spear now has shark fins, which is also a change as before you had to source your own shafts....

Re: Carbon Fiber Gun structures

When rigging the “Urukay” for a shot you have a rather elaborate line wrapping sequence to sort out. On most open muzzle guns, e.g. a Riffe, the line running forwards from the shaft wraps a short...

Re: Carbon Fiber Gun structures

Although spearguns are needed in different lengths for different jobs, and that has always been the case, it seems to me that modular bodyweight guns could be made for different shooting powers and...

Re: Carbon Fiber Gun structures

The company have replied and they say that the gun is pressurized via a hole in the bottom of the stock which is plugged by the reel mounting where they fit a threaded cap. So the access point is...

Re: Carbon Fiber Gun structures

C4 Carbon do talk about their molding procedures, but it is only that used for their fin blades, they don’t say much about the guns at all. The "Urukay" gun came with no instructions, but I guess...

Re: Carbon Fiber Gun structures

That is what I thought originally, but there would have to be an air feed attachment to the bladder and I cannot see any sign of where it was on the gun. The recessed feature in the front of the...

Re: Carbon Fiber Gun structures

It is logical to assume that the bladder will have a particular shape and be like a football in a sense. When it is heated the gas trapped inside it will expand and provide pressure that forces the...

Re: Carbon Fiber Gun structures

Solid lumps of resin will be reasonably heavy and the C4 spearguns being of “No Joint Construction” I don't see how any metal will be inside it as a bladder acts as the internal part of the mold and...

Re: Carbon Fiber Gun structures

Re: Carbon Fiber Gun structures

At the sticker price of $1,599.00 RRP I will not be doing that, but it would be possible to X-ray it if one had access to an industrial X-Ray machine, or maybe an ultrasonic scanner. Medical X-Ray...
