First attempt

Unread postAuthor: farcticox1 » Sun Mar 31, 2013 12:54 pm

So here is my first attempt. It is a 300psi pressure washer gun trigger with 1/4" ID stainless tube threaded in, breach load single shot. I run it of my 100psi compressor as I only intend to fire it in my workshop for target shooting. Ammo is 1/4" steel ball bearings. Magnet on left side is ammo mag and magnet on right side to stop ball rolling out of barrel before shot is taken. Adjustable grip is from angle grinder, there was a small amount of welding, everything else is hand made.

Cost = $0

Yes, just a standard pressure washer gun, I got 3 of them out of the rubbish bin at work, they have a 1/4"' pipe thread in the end. Perfect for pneumatic triggers.

I made the countertop aswell out of pineboard.

I'm going to video the full auto to get the fire rate, so I could do this one as well. :wink:

The magnets might be detracting from accrurecy. They really need to be placed above the bb to be of any use/benifit. Research magnisun effect. Not sure that's how its spelt :)
