Unread postAuthor: tylerthetatertosser » Thu Aug 30, 2007 1:28 am

This is my new copper barrel sealing Tee valved gun... all copper is type L.. i havent got a shot from it due to the epoxy still curing... the over all length is about 56 inches... the barrel is 4 feet... and the chamber is about 37-38 inches... the union is half inch and it is my breech load.... here are some pics :) :) Enjoy

That this awesme is thing, sorry about that.
This thing is awesome, what pressure do you take it to?
I would be proud to own this "nug", damage shots or vids?
:twisted: :P :twisted: :P :twisted: :P :P :twisted: :P

Edit: What dimentions? , like what calibre?

What does the Epoxy have to set in?Don't tell me you epoxied the fittings in.

Don't be afraid to add some damage shots and a video when you can,nice gun always been a fan of copper.

Looks like it will be a nice high-velocity hole puncher when you test it :)

What pressures are you planning on taking it to? For that chamber size it shouldn't be too hard to get to 250 psi or so with a shock pump which will definitely give you a considerable power advantage.

Looks great, but I think you should add a barrel support between the end of the chamber and the barrel.

The fittings and pipes are held together with epoxy, but if the surfaces are properly cleaned and sanded, and the epoxy is mixed and applied correctly, the joints will hold at least 400psi.

He wrote that a while ago... SB15 was asking if he had fired a shot yet. Anyways, nice cannon. What is that thing between the female adapter on the piston valve and the other components? It appears to be clear. Also, why did you epoxy the fittings in when you could have soldered them? I am not necessarily challenging the integrity of the fittings, but I am sure that soldering them would allow the cannon to take higher pressures safely. And finally, why is the union so far from the piston valve?

Again, nice launcher. My copper piston rifle is one of my favorite spudguns.

He epoxied the fittings together because I told him to. He owns a basic pencil flame torch kit; which heats rather slowly, and was having trouble soldering the multiple fittings in the piston valve area without melting joints that had already formed.

After taking my copper BB gun (which is also assembled using epoxy) to 300psi several times, I felt that epoxy was plenty strong for any practical pressures. Good quality epoxy has a tensile strength of ~4,000psi. Good quality lead-free soldering alloys have a tensile strength in the range of 5,500 - 6,500psi. Solder may be slightly stronger, but neither will fail in such an application as this.

the thing you are talking about is a compression fitting that i found...

and i did some shooting today before my pump broke, it shot very well...ill add the damage pics with the video i will make soon.
