I just might have to break this one out of storage to get some videos for you guys as i never took any when i was using it. And Jared, i'm not too confident on taking the pressure up above 100 on those diaphram valves arent they rated for 115? i'm really not surem but if they are, then i'll just hav...

yeah i built this before i knew about the danger of those fittings, i have long since scrapped this to built a small barrel sealer, but thank you

Thanks guys, sorry for the lack of damage pics, i'll try to get those up asap Like i said, it put a hitch ball through an oil drum at work and for distance, i can only guess. The highest I brought it to was 95 psi, and I shot a 2" allthread stud 350+ yards before it hit a tree. Its a lot of fun espe...

Let me know what yall think

The piston is 2 3" endcaps with a rubber washer bolted to one end. It seals a 1.25" x 20' barrel, perfe...
