simple co-ax with attached stock

chinnerz · Thu Jan 14, 2010 10:01 pm

this was my first attempt at a coaxial valve, so be nice

the piston was cast from hot glue, and uses a 2mm thick piece of rubber to properly seel the barrel.
barrel is made from a hollow 10mm OD aluminium rod
the coax valve is made from pvc,
I’m using a modded blow gun for the pilot valve.
the stock is made from pine and painted with an urban camo.

im planning on running it at 100 psi

amazing
i would have just used a 6mm barrel but still you should put a steel of brass chamber so you can crank up the presure

love the stock 8)

ahh i c, the grip was done with a dremel and a wood carving bit. and im in Australia, the closest to what parts you are talking about at made from cast iron for me. cast iron isnt rly the stuff you want to use.

Very nice for a first effort

let's see it in action though!

I like the ventilated trigger, nice touch. The barrel looks a bit skinny though, it would do well with an integral suppressor. All you have to do is drill a couple of ports around the muzzle area and sleeve it with a bit of larger diameter pipe, applying copious amounts of epoxy of course

Galvanized fittings are everywhere here. Perhaps give them a try.

I quite like it. The stock is perhaps a little boxxy but the camo and grips look nice. Quite well made, good work 8) .

Awesome i love hearing about new Australian spudders.

yeh very nice i'd love to see a vid? good job

chinnerz · Fri Jan 15, 2010 6:49 am

fitting a scope right now, and im planning on casting wax ammo, video will be up when that is done

The barrel looks a bit skinny though

ill look into that

Cosmic Muffin · Fri Jan 15, 2010 6:53 am

more aussie spudders, good to see. nice work man

Nice, An unconventional stock, and cool camo, I like it!

Thats very nice job! It kinda looks like P90 but with longer barrel

You have huge potential to make gun replicas especially with the dremel. Its a perfect tool for woodwork and it makes every project go faster. You could get one of those routing knives for it and make holes in the wood to encase the air tank so it looks cleaner.

I tell ya... my first air rifle with wood on it was pure ugliness... this actually looks pretty good

btw. what dremel you got? I'm using a dremel 300 series

i am not too sure on that one as my mate is using it atm, but if i tell you that it came in a toolbox with a bunch of bits, and it has an electronic speed guide on the back which essentially has a screen on the back which tells you on a scale from 5 to 28 how fast it is going would you have any idea which one it is?

Nice, An unconventional stock

yeah the plan was to make a bulpup sniper rifle

i have to agree with everybody else on the fact that this is an amazing gun. the stock, the paint the sight, and the fact that it is about 27.39 times better than most peoples first cannon.

but you seen to miss the point of a coax gun. the ammo is meant to go all the way back to the piston for max preformace.

i don’t think so, it has a breach to make reloading twice as fast and it gives me the ability to use shot shells (which i make), but i see your point, it would be far more efficient if i left it as a muzzle loader
