Whimpy gun...

Unread postAuthor: deathbyDWV » Wed Mar 31, 2010 10:11 pm

I was bored last weekend so I decided to throw together a little gun out of all parts I had around the Garage. (capital G for crowley) this is definantly the wimpiest gun I've made...

I was actually suprised by the power. It shot a bouncey ball about 150 feet... (and one into my garage wall :oops:)

It needs some paint...

Good job on the handle and the breechload.
With a bit of paint this will be a clean launcher.

Yeh, it's on the sprinkler valve, facing down in the same direction as the trigger.

Not bad at all. Some footage of it in action would be nice. The breech load is also a nice touch, and asides from primer it's done rather neatly.

I'd be a little worried about this:

Yep SB15 I am. Since it's old parts the coupling or bushine must have had something in it. It wouldn't go all the way in even with a rubber hammer. I'm surprised you're the first one to notice... I ended up sanding it and putting alot of epoxy on it. I still won't trust it to very high pressures though...

Tha schrader is right between the tank and the valve like Genious said...

The breech was made by drilling a hole almost big enough and then dremeling out the rest...

Sorry no video... I don't have a camera except my phone and it's my only was of taking pictures...

I did bad with the primer cuz I'm used to using clear... :lol:

it may be wimpy but it sure looks cool. i really like it. i really like the ball-valve breech. kinda messy with the primer but i don't really care. others do. I've always kinda liked that kind of look.

Thanks. It is fun to show people this. I shoot I and they're like "woah you made that? That's really powerful!" and then I pull out my big cannon and punch through 4 sheets of plywood for them... :D
