So the night before March Meltdown VACC gave me a Mad Hornet to do my worst with and it didn't take long for me to develop a plan since I had the whole car ride back to think about it.
Inspiration for the name goes to Twitch, whose "Captain Bojangles McPoonsnatch" convinced me to pick something more absurd.
Main problems with the stock blaster
- Low tank volume
- Tiny pump
- Annoying pump handle
- Extremely leaky barrels
- Metered output
Solution: barrel replacement and tank expansion.
I had to move the barrels closer the the pump housing in order to get them to clear the lip inside the shell that retains the turret.
To do this I faced the turret base using a lathe, then made polycarbonate brackets.
I used 3 inch barrels because the output of the trigger valve system isn't that great.
And done. All I have to do is hook it up to a regulated supply of air from a backpack tank or compressor and it will fire a dart each time the trigger is cycled.
While I couldn't solve the metered output issue because of the design of the valve, I am getting respectable ranges. The range however is highly dependent upon the pressure level supplied to the blaster. So if you fire at 20psi, you're likely to only get 20 feet or less. But jack the pressure up to 50 or even 70 psi and you're shooting 50 to 60 feet.
I need to do more range testing at work, but so far the semi-auto shooting is working great and is very consistent. I just have to make sure the trigger cycles all the way back and all the way forward or else the valve might get stuck open.
