Hi all. It's been quite some time since I've logged on, I like the new site layout! I just realized I only have a thread on my 4L propane cannon and not my pneumatic. Just dug it out of the basement. I will clean it up and work on removing the non pressure rated bell reducer in favor of some bushings. I figured it was okay to post since the category pictured antenna launcher has one too. It's been up to 140 psig more times than I can count, but i figured I should probably fix it anyway.

A nice old school PVC/Sprinkler setup, looking good!

It looks like the air flows into the handle when firing. That area basically needs to fill up with air before it can produce a force down the barrel. Might be effecting performance.

*edit* nevermind, saw the valve is in front of it.
