SpudFiles

Well I just finished building my new Harley Davidson; spudgun that is.

This thing is just so bad, it deserved a tough name. Dubbed the "Four Barrel Marauder" mainly due to the fact that without barrel it resembles the number 4, and I made four uniquely different barrels for it. It boasts a sleeved golf ball barrel, a tennis ball barrel, a 2" ported barrel, and a 3" t-shirt/candy, etc. barrel.

I used a 2" barrel sealing diaphragm valve with a 1" flow, piloted with a blowgun. They're relatively easy to make providing you do a little homework, and cost around $17 in parts sans the blowgun. I paid $15 for that alone, but it looks nice and functions well.

The gun consists of dual 3"x12" chambers. Everything is NFS-PW except the 3" couplings and the bushings inside them. With pressure rated pipe filling the holes I think it'll be fine. I'll post pictures of the barrels after paint, but for now enjoy the gun! -Lp

awsome paint job and nice valve, you're one hell of a craftsman

Very original. The paints sweet. What Psi?

Very nice gun. If you want to get a little more power out of it, use a 1.5" porting valve rather than a 1". The new valve will be just as cheap as your first one, and will give over 2X better performance

Thanks for the kind words.

My current compressor has a limit of 100psi, but I do have an electronic tire inflator that will take it higher. I find though, that 80psi is ideal, and provides substantial power. I was tinkering with the idea of a 1.5" port, I didn't want to go over 2" with the tee, and the 1" seemed to work well. I use a heavy duty neoprene seal that I cut to fit snug and only 'breathes' a small distance between the breech and the end cap, an equalization hole was also drilled. This being my second pneumatic, I wanted to go larger than the first as far as valve porting is concerned, on the first gun I only used 3/4's of an inch.

My next project will probably use something a little bigger, but this baby dumps some air! -Lp

I didn't know the made bushings in DWV. Usually they are bell reducers in DWV.

I assume since they make NSF-PW bell reducers then DWV bushings exist also

Really nice esspecially the valve but can post some pics of the barrels

that looks so sexy

Ya dude thats awsomse looking!

good job kicking u a dead topic

I like the firing mechanism, it looks nice. I'm new to this whole game of spudguns. Could i ask what is firing mechanism (the blue thing) and where did you get it? Thanks heaps
Also that wiki page is really helpful but i am having trouble understanding how the piston valve is incorporated into this gun i have read through this but still having a bit of trouble seeing how it fits into this?

Dont kick up dead topics

Hey, hey relax a little bit! I don't want to defend anyone, but if someone wants to praise a good gun, let 'em! CC is not very *ahem* fourm smart, but at least cod has constructive critisism. Most of us have heard the "NO DEAD TOPICS" line. Not trying to start a flame.

BTW - Great gun, I LOVE the paintjob! I have a freind really into harleys, He would love to see something like this!

Hey all, it been a while since my last post!

Thanks for kind words that continue to come in. I just shot this gun for the first time in months, but it still looks and performs as good as it did when I first made it. -Lp
