The super ghetto gun

Unread postAuthor: nadjatee1996 » Mon Feb 14, 2011 8:22 pm

As from my older topic, I've been wanting to do this because 1) building a ghetto gun isn't very hard. 2) When I first arrived here on the forum, I was clueless and had to ask a ton of questions, annoying myself and maybe others. and 3) I wasted about 40 bucks buying materials for the gun, while in reality, after building it however, I could've saved like 20 bucks. I am assuming that you have at least a power drill and a pump.

DISCLAIMER : You may not like this design, but this is for the people almost completely new to making pneumatic air guns, this is merely a humble design I made to help out newer people. I will not be responsible for the murders and injury of innocent plywood boards, cardboard boxes, fruits, potatoes, produce and/or walls.


The number in the parenthesizes mean part number, not part amounts.

Materials : Hose/Blow gun trigger (1)

Epoxy (2)

0.6 CM tube, recommended length is 6-12 inches (3)

Schrader valve (4)

2 Liter Soda Bottle(5)

Make sure that the top (threaded) of the soda bottle fits with the bottom of the hose/blowgun trigger ( the threaded part too)

Step 1 : Drill a hole big enough for the Shrader Valve(4) onto the bottom of the soda can bottle(5).

Step 2 : Very carefully, epoxy(2) the Schrader Valve(4) into that hole

Step 3-1 : Screw the top 2 liter bottle(5) into the bottom of the hose handle(1).

Step 3-2 : Test for air leaks by pumping air into the bottle(5) and trigger(1), then firing the air. NOTE : Some air may leak out if the hose handle you bought is similar to mine, the top has an un-fixable leak in it.

Step 4 : Epoxy(2) the 0.6CM tube(3), now the barrel, onto the dead center of the nozzle of the hose trigger(1). DO NOT epoxy it off to the side, as it may fire weird, or not fire at all if you do so.

Now, pump this baby up and put in a BB down the barrel, ready, aim and fire!!!

ENDING NOTE : If you do not have BB's in the house, or you just want to fire marbles, do the exact same steps with the 0.6 CM tube ( barrel), but with another tube with an ID [internal diameter] matching the diameter of your marble.

All BB's can only be fired once.
