Well title says it i finally got off my but and took some pics of it.
It's got a 4.in by 2ft chamber and 5ft 2in sleeved in 2in for the barrel.
It's got good power and thats about it. O got a chamber fan just got to install it.

Heres a pic of thebarrel next to a measuring tape you can see it says 60in. witch is 5ft. Since some people were for some reason skeptical i made it. Don't know why but i guess thats just some people...

Nice use of reducers rather than dwv cones.

On your terminal where the wires go into the gun I'm seeing some charring. It almost looks like it's not quite air tight. That could lead to other problems.

Tons of questions, your cannon does not appear to have a metering system. How do you measure the volume of propane accurately? I might be wrong as the picture doesn't show the other side of the cannon. Also no hose clamps? You're looking at a lot of leaking and as a result some inaccuracy when metering.

It's a good start!

Well the burns are from the old bolts i had that were to small ive replaced them with bigger bolts, no more burns. Um its got a metering system, i use that presure guge to measure the propane, you probly just cant see the ball valves in that pic. Never had any leaks if i did i would put hose clamps on it... Also Jack cant shoot it now way to cold maybe if i get a warm day.
