Swamp's Pneumatic

Unread postAuthor: PCGUY » Sat Feb 05, 2005 6:24 pm

<div align="center">SWAMP PNEUMATIC

Provided By - Swamp

It has s 3'x3" chamber, a 2" baccara sprinkler valve (modded of course) and a 5'x2" barrel.

I think I was most pleased that the stand came out as well as it did. Amazing what you can do with a couple drawer slides and springs.

Things I could have improved:
1. elbow on the top of the sprinkler for the blowgun hose would have allowed me to have the chamber and barrel closer together
2. The stand it too light. I had to attach a cinder block.
3. Actually waited the week for the krylon to cure, oh well.

The stand. It's 2 circular pieces of particle board with 2x4's between them to hold the legs. Each leg has a slot between the 2x4's that it fits into. Even without bolts through the 2x4's it could support my weight easily.

The stand with the rotating disc attached to the top. It's just a 3/8" bolt through the entire thing with a couple of fender washers (and some grease) between the top 2 pieces.

The mount. It's 2 pieces of 2x4 cut to fit the barrel and chamber screwed into another 2x4. Attached to the sides are some 3/4"x3" project wood (the wood at lowe's/wherever that is actually straight and finished). You'll see the 2 springs attached to a couple of steel hooks.

Each half of the drawer slide is mounted to a piece of project wood. The bolt you see in the bottom piece is a carriage bold I tightened down until the top was flush with the surface of the wood.

Dose the recoil system not lower power slightly?

If your getting chased off a police dog, try not to run through a tunnel then onto a small see-saw then through a ring of fire. They are trained for that!
