Fish Killer 2
Posted: Thu Nov 15, 2007 8:15 pm
My Fish Killer was a fun gun, but it was quite bulky for something that only shot .40 blowgun darts.
So a couple weeks ago I sought out to improve upon it. I originally intended to make a coaxial because they're the low profile, but I wanted to maintain the quick-disconnect breech that I had on my first gun. In order to do so, I decided to make a coaxial chamber (1.5" x 1/2" sch 80) with a tee so that I could branch 3/4" pipe out from it, use a couple elbows, and bring my QEV behind the chamber with the output port in line with it. My blowgun barrel (taken from my original gun) would then slide within the 1/2" sch 80 inner pipe and connect to my QEV via quick-disconnect. This would make for fast and easy breech loading while keeping the gun as low profile as possible.
Here's how it all worked out (unfinished):
I thought my idea was genious. It almost reminded me of a Klein Bottle. Then I remembered seeing something on here before that was very similar- The Bergles Cannon. Oh well, it's still cool!
All that I have to now is find the pistol grip blowgun I used on my other gun and this one's finished.
I'm thinking now that the 11" of 3/4" pipe connecting my QEV to the chamber might be somewhat of a restriction. No big deal though... I sort of had to make that long to give my barrel room to slide forward to accomodate 4" wire darts. I couldn't downsize anything either without sacrificing the quick disconnect or creating a weak spot where I epoxied the barrel to the male fitting.
Enjoy.
