super-modded+chambers and barrels

Unread postAuthor: daxspudder » Sat Aug 16, 2008 4:41 pm

So ive finally decided to post my pneumatic, all the chambers and barrels, simple as that...

my pump rifle
Image

my super-modded valve, minimum pilot volume, faster opening, faster closing, diaphragm opens wider, the big washer spaces, and holds down an O-ring, the adjustable plumber's tape is just to hold the pump on
Image

all my chambers, 24"x2"(ball valve is a safety/diaphragm protection),15"x1", and 7"x1"
Image

my barrels, (just diameters, longest is 5', guess the rest from there...) 1/2",3/4",3/4"slide loaded paintball barrel, 2">3/4"water barrel,1",1.5",2", sch21 GB barrel, 3" baseball barrel/shirt launcher
Image

My shop, dremel, compressor, saw, wrenches, all I need to make my "toys"

Say you were shooting at a 4'X8'X3/4" sheet of plywood standing 8' straight up and down exactly 134yrds away?

Cool pumper there Dax. I've not seen one connected up quite like that.

Could you go into a little more detail on your super-mods?

Now thats a big collection, and on top of it, they are all nicely stored so its not making a mess! (I had a few guns swarming through my bedroom for months)
Cool paintjobs you did there.

How well does that valve perform (in comparison to a normal modded one?)

1st, I love my vans I have 5 pairs, I never wear laced shoes if possible.

2nd,@jrrwd, it really depends on what i want to accomplish with the ammo, because I might be firing a dart out of a small barrel, or trying to puncture it with golfballs, or outright decimate it with a 2" 2lb lead ball, understand?

3rd, the supermod: using the concepts that make a piston valve more efficient I rebuilt my mod, which honestly works 5x better. It's built with a thick brass 1/2">1/4" reducer, a 1/4" nipple, 1/2" brass end cap, large washer, set of sink O-rings, and blowgun. Several parts have been modified, the brass end cap is cut in half to create a tight fitting angled "nut", the top portion of the valve has the inner piece of plastic removed, the diaphragm's center nipple has the ridges that come off the center removed which allows the diaphragm to rise to a maximum for best flow(about 1/4" higher than normal), the spring is shorter and stretched. I cut O-ring grooves in both the top and bottom edges of the valve with a dremel, the bottom one is held in place with the "nut" and the top O-ring is held in by the washer, the whole thing works like a compression fitting. The valve opens amazingly faster than a regular mod, and gives no fart or whoosh of air after the trigger is released, it seals very fast... whenever I service it next ill take a few pictures that I'll post to clarify, maybe today...

4th, the rifle: it only take 10 fast pumps to get up to 60psi, the valve has no issues with being filled with a bike pump, I love the 1/2" barrel that is shown in the pic with it, nerf darts, markers, potato slugs, all fit great and are accurate over 300 feet, yes 300 feet, with like 40 pumps that is, from 100 feet a nerf dart broke skin...

That's pretty cool, the paintjobs too.

And may I ask you something off topic?

The name daxspudder? Does it come from the honda dax?
I drive a skyteam PBR (Honda ZR imitation.. from CHINAHH) myself.
