Wondering if we have any gun makers on here?

Would be cool to see some custom gun builds and also share ideas and test results.

Maybe even meet up if someone has a pool and do some shooting practice!

I myself have made a couple guns starting from an ambitous timber double roller as a first gun then onto multiple different arangements of rollers, then comming back to conventional two bands. I am now making guns straight out of carbon fiber.

I think it would be cool to have good database of spearguns used in nz and design specific custom gun that meet our conditions, so please upload some pics and share some ideas!

Here is my 2 band full carbon 110 with 85cm of band stretch 14mm small id bands at 350 percent stretch 7mm spear. full custom carbon body with carbon handle. needs alittle bit of balancing to finish it off but hopefully will be an easy swingable snapper snooping weapon. 

do you think a reel is mandatory for snopping? 

dont know the exact cost break down but a list of things needed is something like,

(off the shelf)

spear

trigger

bands

dyneema

(hand made)

body 

handle

muzzle

If someone wanted to make one out of wood (highly recommend for first project) you could buy all the off shelf parts top quailty for around 350ish buy some hardwood and go at it (assuming you have wood working tools). With wood you could also laminate with epoxy and finish with epoxy but thats another added cost. 

The ermes double roller mech are so so very nice. the ceramic pulleys are for inverted roller?

You can see the mould off to the right of the pictures its the white thing.

Method i used was wet lay vacuum bagging in a mould. Because i use a mould i dont have an internal core only stiffeners at certain position to help transfer load from top skin to bottom skin. When i lay the carbon i always make sure to know what the gun will be as an inverted roller will need more reinforcement on the top of the gun while a conventional gun will need more on the bottom, a roller can be even top and bottom. The muzzle roller diameter is different for most of my guns as when i drill the holes it can be up or down a couple mm. I make them big enough so the rubbers dont rub on the body but small enough that the rubber line up nicely with the shaft.  

Ill do a write up of the inverted next but would like to go test it first. anyone got a pool in auckland willing to let me shoot some foam .

will post some highlights here, 

start with a computer model.

3d print some moulds 

mould some carbon skins 

add some reinforcements

make a handle 

smack it all together and boom inverted carbon roller with rear rollers 

That cuttle barrel looks very cool any pics from the top to take a look at the shape?

Do you think when loading, the rubbers rub on the body making it harder to load?

Popped another out of the mould from previous post but made it a conventional setup. bit of a different finish gold foil in epoxy, may have gone slightly over board with the foil.

And because I could not buy the ceramic bearing blocks I wanted, I just made some up. Something spearfishing related to do when the weather was horrible.
