3/4" bolt

Unread postAuthor: Arborman » Tue Mar 20, 2007 5:09 pm

I'm sorry if this has already been asked.

I want to make a simple, yet efficient (little or no leak) bolt for my .75" mini. I was thinking about breech loading like on some of my other guns, but I just want to try a bolt of some sort.

Get an inch tee and an inch coupling, then take a a small piece of 1 inch pipe and fashion it so that it can slide through these wo pieces . With a lathe I would guess and then after that works, drill a hole in the bottem of the pipe so that it lines up with the bottem of the tee and another hole so that when the pipe is pulled back a ways it lines up with a hole on the top of the tee. Plug the back of the tee with a PVC bulkhead and have a small spring inside pushing the pipe foward, which is also sealed on the one end nearest the spring. Cut a slit for a bolt handle on the back side of the tee and connect a rod to the pipe inside. The pipe that sticks out of the tee and into the coupling try to cut down a bit so it slides in the couipling smoothly and perhaps use a coupling. On the other side of the coupling connect the barrel. If that makes any sense at all well there you go. I will post a sketch if my scanner ever decides to work. :x

Wait, so you want bolt-action breech loading or a semi-automatic bolt? Breech loading bolts are extremely simple, all you need is a drill, a screw, your barrel, a piece of pipe slightly smaller than your barrel, and some electrical tape.

My sketch is of a simple bolt action breech design, pretty much what you are saying.

Well then I am not sure how to explain it to you, its a pretty simpl design. Your baically trying to make a paintball bolt for a cannon, one hole allows for air to pass throug and the other opens for ammo to be put in when the bol ti pulled back. The bolt slides in a tee and coupling with the aid of some lube and perhaps some orings. A spring can be place behind the bolt to hold it shut or vice versa and hold it open.

Just find a piece of pipe that fits snugly over your barrel and cut a hole in your barrel. So you slide the piece over the barrel and it covers the hole. If this is for paintball, use a 3/4" CPVC barrel and 1" CPVC can go over the barrel. It won't make a perfect seal but it's really easy and it will definitely do the job.

That pretty much is my idea but a simple version, however the chamber would attach to the coupling.

Ok, what if I used a .75" repair coupling? How much power would I lose from that.
