Coax fast build [updated]

[MRR]

This is a build on a topic reply.

I build it in about 1 1/2 hours and it is my first coax ever.

Total length: 99cm
Chamber: 1", 40cm + 20cm galvanized steel
Barrel: 15mm, 78cm long

The piston is basically the one I described on this how to....

The barrel support...


13cm ~ 5.12inch nail dart


Some damage (unfortunately the flyer failed)


It was pretty fun to build this and the power is better than I expected for a first build coax.

Hope you like it .

[sniper hero]

I like it:D
and wow that's a good way of building barrel support and can be improved.

good work!

[Biopyro]

I do like it!
Is it easy to hold and shoot? I get the impressing that if you rotated the wye and lengthened the fill arm, that would make a convenient bipod.

What sort of pressure are you feeding it? It looks hungry for 400psi

[MRR]

I didn't make a plan to build this coax, just read a topic on the forum and had the idea. It was absolutely spontaneous.

It sure looks like it can handle some pressure but i only did some test shots @120 psi.

The barrel support is a pice of pipe 4 screws and 8 nuts but it turned out to work really well.

I will add some damage pics tomorrow...

wow thats a great looking gun

your barrel support gave me ideas 8)

[starman]

Very sleek indeed! I assume the bottom angled piece is used as a tank extension as well as a handle...?..

Simple, well constructed, good looking cannon! Nice job.

[MRR]

The angled piece is just random because I haven't had the fittings (without using some from my other project) to attach another tee.

I like it even more due to the different look and it balances very well.

[psycix]

Very nice!
I like the chamber setup.

One thing: your blowgun is mounted backwards. It isnt meant to take pressure from that side.

[MRR]

I know, but it does it's work very well this way and it never leaked before.
I don't pressurize it over 120psi (compressor) anyway but as soon as I go higher I will find another solution.

[Totem123]

WOW! i'm new to this iste, but this is defiantely one of the best guns i have seen!
i hve a few questions:
does it work for paintballs?
does it work for bb's?
can you please post the plans on how to build it?
and you sound like you know everything about building guns, so can you like send me messages of good gun designs that i could try out( make them bb or paintball most which is what i really need)?

[airheadnoob]

nice 1 1/2 hours and it goes through wood
your gun is a coaxial qev
and swap the Y with a T

lol totem123 asking you loads of questions

[MRR]

@Totem
if you think this gun is impressive then you really haven't seen much of this website. This was just a spare time build and the guns itself is no more.

To your questions:
You find every possible information to build such a device here on spudfiles, you don't need my help....
Learn, have fun and build a cannon that fits to your ammo of choice.

[Totem123]

thnx dude.... but i really cant build cool stuff i cant even build a stupid small not working pantball sized gun/....
im dumb i guess :p
