Breech Loading Barrel

Unread postAuthor: PCGUY » Sat Feb 26, 2005 11:59 pm

<div align="center">BREECH LOADING BARREL

Provided by Boogieman - <a href="http://www.advancedspuds.com/">http://www.advancedspuds.com/</a>

Breech loading is awesome, it is much faster to load. I think it took me about 40 seconds to load a spud with the ramrod method, and now it takes me 5-10 seconds. Once you try breech loading, you will never go back to muzzle loaders.

Type 1: Cam Lever Coupling

This is the method I use on my spud gun.
I use Banjo fittings. You can get them at many farm equipment stores. They are used on sprayers on farm equipment (as in fertilizer, pesticides, etc.) According to the banjo website their operating pressures are 125 PSI, I believe this is not the max PSI, only an operating range, as you may already know they can hold much more pressure before failure. (a wild guess would be 300 psi max, or more?) They come in many sizes, I have seen 1" to 3", with many variations on the kinds of fittings.
<A href="http://www.banjocorp.com/">http://www.banjocorp.com/</A> for more info. I use model 200D and 200A fittings on my gun. The pics describe the method I made the barrel. The hardest part is turning the barrel down on a lathe. You can also use a Dremel tool, but it took me around an hour and a half doing it like that.
A pic of what it looks like:

Pic was not too clear, materials include: 2"MPT fitting, 1.5-2" bushing, 2" cam lever coupling, and 1.5" schedule 40 pipe.

This barrel is my breech loading rifled barrel from the SGTC. Notice how the excess fittings have been eliminated for a smooth look.

Type 2: 2" treaded fittings

Pics coming soon....

This method is not quite as fast to load as the cam lever coupling method, but still does a nice job.

To make this type of breechloader, you put a 2" male adapter on your gun. Next take a 2" female adapter and remove the inside ring. The ring prevents the pipe from going through the fitting. The ring can be taken out with a Dremel tool, or a round file. Now just cement and slide the pipe through the fitting about 4-6" and sharpen the side that goes into the barrel. Now just smack the tater on the sharp end and screw it into the chamber.

I would love to have a breech loader of the type shown here . I get tired of pushing the tater all t he way down the barrel . In the future all my cannons will be designed with this in mind.

Mcmaster has "cam and groove couplings" from 1/2" to 6", but you'll have to go with metal for anything over 4", and the 1/2" selection is rather limeted in anything other than metal... I think they only have 1/2" plastics with hose barb connections.

ok thanks leadbath. Hey you know with the other way to breech load how do you get the screw on thing all the up the tube to connect? And would that work with a paintball?

Thanks
Tommy

"screw thing all the up the tube to connect" Talk scence man!
...do you mean using threaded fittings? If that's the case, you can use the technique described in the above artical.

This is a pretty "complicate" system but it would work great for changing barrels.

I found out while making my barrel knife that an angle grinder with a wire wheel strips pvc in a hurry, nvm using a dremel when i got a grinder! That would come in super handy for changing barrels. HMMMMMMMM, :) I love this place.

Much better, its faster, more efficient also because the spud is closest as possible to the breech.

you could probably have it glued in 30 minutes tops, it depends on your tools, i've made similar loaders in 10 minutes
