I figured this would be a good first post after getting validated. As some of you may have seen on the other forums, I took the SNAP design, and I made it my size, also known as awesomely big. This turned out a little "eh". Well, this time I took the PVAT 2.0, also known as VenPVAT, and made it awesomely big, and dubbed it the "Effeminate PVAT", and this is the writeup.

First, the whole safety rant: Never use globbity plastic cements, always wear eye protection, protection is important, and wear a respirator when exposed to fumes. Always use a vice to hold your junk, not your or other people's hands. Now, onward!
First, stuff needed!
Posted Image
Stuff you need from this pic is the 1/4" bolt(preferably carriage), 5/8L beveled faucet washer, 3/16" ID x 5/16" OD orings, 1/8" pipe nipple(needs to be hex), 1/2" to 1/8" bushing, 2" to 1/2" bushing x2, 2" coupler. Not pictured: 1/8" cap, strong spring, spacer.
Posted Image
First, sand the smooth part of your bolt. I did this by placing it in the chuck of a drill and spinning it while holding sandpaper to it. Sand until the nipple slides easily along the bolt.
Posted Image
Assemble the rear of your PVAT like so, using teflon tape between threaded connections, and PVC cement between slip joints.
Posted Image
Drill out your 1/8" cap with a 1/4" bit.
Posted Image
Drill a 7/16" hole in the side of the tank.
Posted Image
Tap the hole with a 1/4" NPT tap.
Posted Image
Yeah, I tapped that!
Posted Image
Assemble your pin setup.
Posted Image
Assemble the tank with a 1/4" fitting in the tapped hole. Add a pump, and your good to go!
Posted Image
You now have an EPVAT!
You can just use a normal 2" coupler for the body, I wanted mine disassembleable in case of problems. You can also just tap a 1/8" hole in a plug for the back, again, this was a first attempt, wanted to keep possible problem places to a minimum.
Ranges:No official ranges, as it's crazy windy here.
Unofficial ranges are as stands:
With Absolver and stock suctioney's:Around 60', with roughly a 10' spread, at 4 pumps
With short improvisational barrel of around 2.5" and stock wistler:scary fast at 3 pumps
With 19 barrel absolver soon to be posted-40' to 50' with a 15' spread.

Also, lithium grease is the suggested lubrication method. I happen to have a can of liquid wrench lithium grease, so good to go.
Note: There should be an o-ring placed in the front coupler to assist the seal. I found this out after making this, so there isn't a pic, but it's fairly obvious when you look.

I apologize about the 'Effeminate'. It's really supposed to be E P I C.

Holy crap, that thing look pretty damn powerful. If you had to guess, what would be the PSi in there when it's full?

I've actually calculated it, and it's about 45psi after 3 pumps. I can do 4, but it's pretty difficult, even for a guy of my size/strength.

Tire pressure gauges can be had for $3-5 and often times use 1/8" pipe thread (not tapered though). I use them on everything, just so I have an idea of the pressure and don't end up murdering someone by accident.
