Notice the ball valve breech, it works great.

Image

1" (C battery) barrel, 2" chamber.

ALL NSF-PW.

Image

It's very easy to hold and fire. The barrel is perfectly parallel with the chamber.

Image


Image

Image

I drilled and sanded out the ball valve so it is the same diameter as the barrel, c batteries slide right through it,
if you are familiar with C batteries in 1" barrels you'll know they fit with no play around them whatsoever.

C batteries can not be loaded with the breech because they are slightly too long.

Found this cool PSI GAUGE. Image


This box was hit by a piece of chalk.

Here's a video.

Actually, not a bad effort here. Looks like it has some decent performance potential with higher PSIs. I like the breech loader and the trigger configuration.

My only real complaint is the towel/rag thing under the front barrel support. I'm not sure what it's for and it's pretty ugly. Also might not hurt to scoot the barrel support out as far as you can get....stiffen the barrel a bit more.

YA, that rag is temporary,

I'm going to paint it camo in a bit, and the rag will go. I will make a new support/fore-grip that's smaller and easier to hold.

nice work, it's a little ugly with all the primer stains and the rag, but a good gun nonetheless.

It looks to be turning out well. I can't say much that hasn't already been said, so I'll get on with something else now...

You see, this was the unanticipated problem with my user name. Everyone shortens it to Rag, and then whenever I see the word rag out of the corner of my eye, I assume it's something to do with me, then read it and find out it isn't. :roll:

It just shot a paper towel through a tool box (all the way through).

Very awesome. Made 3" almost perfectly circular holes on the front and back of my tool box. :)

A paper towel?

I dont think i believe a paper towel went through a tool box. I dont think you can put jsut a paper towel through anything without hardening it or putting something in front of it

Actually, a wet paper towel will put holes in lots of things, as long as it's relatively close range. I put one through sheetrock once.

must have been a really flimsy toolbox though.

I think a small wooden shim in place of that towel and a bit of paint will make this cannon look really nice, but it's not really the aesthetics that count for a lot with me...

I know that, I'm due to be removed in a few decades, although I fully intend to put up one hell of a fight. :twisted:

I'm not kidding, that was JUST a paper towel, I can prove it.

Watch the video with the tool box carefully, (pause it at the moment of impact) you can see paper towel shreds in the hole.
