Hello all. i'am new to the forums here i have been building guns for about 3 years on and off... mostly all combustion type guns. Here is the most recent gun i have built. and over under type air gun.

It is built using sch 40 for both barrel and air chamber. The barrel is 1 1/2 inches in diameter and 4ft long. the air chamber is 2 inch in diameter and 4ft 6inch long. Has the schrader valve @ the end to add the air. Also put a psi guage to get air pressure reading. The valve is a basic lawn genie 1 1/2 inch that i bought @ home depot for like 23.00 works awesome. never had any problems with that. it runs off the contol box that holds the three 9v batteries. has a seris of three switches. a toggle and two button switches. its pretty powerful. i have had it up to 110 psi and shot a pvc rocket thru a old computer (had a thick metal casing around it) and went tru the outer casing and in the hard drive. ***PUFF*** - Content removed.

looks nice, you would get alot more power if you used a modified sprinkler valve instead of using an electrical solonoid setup. By the way where did you find the NOS arming switch you use? I was looking for one of those to use as a switch.

They are generally used as NOS arming safety switches. NOS for a car that is, god forbid you pressed the button nearing a red light by mistake... go safety or go +80 horsepower at a red light. Anyway just upgrade to a blowgun its much stronger due to the faster release of the air from the resevoir. Nice gun though.

I am proud too say,I just might be the only person to mod one. If anyone else has tell me,Yes you can mod them, Open up the valve,knock out the flow control knob thing. drill out the hole to make it fit whatever you are going to thread into it.
