Add a lot of tape, going from one end of the chamber to the other. Other than that it should work fine. Nice and ghetto, but wear gloves and safety goggles :lol:

Right now I'm having amnesia and deja vu at the same time. I think I've forgotten this before.

Or otherwise, overlap the one bottle over the other, drill holes and put a couple of bolts into it with nuts on the inside, then it is still serviceable.
really good quote/phrase here

The bottles are overlapped by about 1" and it feels very secure.

You might want to staple through the overlap for extra strength. Dab some superglue around the staples to secure them, then wrap with tape. Of course, do this after you install the ignitor so you can have it open when installing.
Other than that, it looks good for a gun held together with electrical tape.

This is a true potato gun because it is made from material just lying around. I would re-enforce it with more tape though.

Reinforcing it with tape isn't going to do much of anything except keep down the shrapnel if it does rupture. But as long as you're using some sort of aerosol, I don't see too much chance of that happening.
