I understand soldering is the best choice, but could the bonds also substitute just as well as soldering?
Soldering is the best way to go.. If you (your parents) think soldering is unsafe they (you) won't be happy when a piece if pipe shoots off and hits you. No subsitute for copper.

Hmm...but if operating on low pressures, such as 75-130 MAX...

I think JB/Epoxy should hold...

Well to be safe I would still solder.. But If you have to then you have to. But put a lot of epoxy.

I edited the original post with new pictures of the gun rebuilt. I think it is better now.

4. Added a homemade adjustable sight. I saw the idea somewhere on this sight but dont remember who posted it, wish I could give em credit, works great. I can hit a can pretty regularly up to about 30 feet.


Well done, like it :)

It's the design I used on this project ;)
