Step 1: Materials & Tools
-Modded sprinkler valve
- 1' of 1 1/2' pvc
- 4' of 3/4" pvc
- 3 3/4" 90* elbows
- 2 3/4" 45* angles
- 1 3/4" Tee bend
- 2 3/4" caps
- 3 3/4"- 1 1/2" reducers- 1 threaded, 2 non-threaded
- 2 1 1/2" Tee's
- 1 1"-1 1/2"reducers(2 if you don't already have a barrel to use)
- 1 3/4" male adapter
- 1 1" stub out approx. 3" long
- approx. 2' of pressure rated tube 3/8" ID 1/4" OD
- 1 3/8" threaded 1/4" hose barb 90*( if you dont have this you can use a 3/8" by 1/4" hose barb, as long as it fits the tube)
-2 3/8" by 1/4" hose barb( if you dont have the part listed above)
-3/8" schrader valve
-air compressor blowgun piece
- 2 extra small hose clamps, to fit the hose
-drill with 3/8" drill bit
-flathead driver to tighten hose clamps
- pvc primer and glue
-something to cut pvc, hacksaw ect.
Step 2: Preperation/stock Building
Let's start with the stock. The most imposrtant this for all of it is to make sure all pieces are straight and in line with each other. First put in the stub out on the bottom of the Tee. Next the longest piece on the side of the Tee. That will be the top of the stock. I suggest waiting to put on any corner bends yet as it will be easier to put them on later. Now glue on the 45* bend onto the bottom stub out. Be sure it is lined up with the rst of the stock.when that is dried put the other piece on the opposite side of the 45*. It should be about an inch longer thatn the stub out. Again be sure to line it up before the glue dries. Now add on the piece coming from the other side of that 45*. The piece you just attached should be going parralle with the top of the stock. Take the last piece of pvc you cut for the stock and attach the 2 corners to it. These are the most important pieces to have straight. When those dry you can easily put it onto the rest of the stock, then glue it. There should be the other side of the stock still unused, put in a 3/4" stub out and glue on your male adapter. You now have the stock
Step 3: Main Air Chamber & Handles
First take the shorter pice you cut for the back handle and glue it into the back handle. You can also glue on the cap for it. For the front handle take a piece appeox. an inch longer than an invisible stub out( that means the two connectors that hold the stub out touch eachother and the peice cannot be seen, make it about an inch longer than that) glue that into the front reducer. Do not glue the corner on to that without put the longer handle onto the corner first. Glue the longer handle onto the corner and then that onto the stub out. The length of it will make it easy to align with the rest of the gun and other pieces. Drill the 3/8" hold into the cap and install the schrader valve before glueing.
Step 4: Adding the Sprinkler Valve & Stock
The last thing you have to do is screw on the sstock. Use some teflon tape for it. since its threading you can perfectly align it with the handles. After that Your gun should be completed.
Step 5: Extra's & Painting
1. the threading on the reducer where the stock is attached allows you to put on any type of stock to suit your needs. You can change the size of you air chamber, how it's held, over all weight, and looks.
2 . using tube for your blowgun trigger lets you postition your trigger anywhere. All you need is some electrical tape to keep it in place.
3. with the stock you can look right down the gun for easy aiming and it allows you to add a sight.
