Here is my new ghetto gun which i made yesterday, the materials are a sprite bottle, a fanta bottle and some pvc tube which fits very tightly into the bottle top.
Here are some pics:








Havn't got round to firing it because i haven't got any piezo units left, so i will have to wait until i go into town next

So anyway, whats everyone rekon?

nice but make sure it doesn't blow up on you. seriously a few more layers of tape will help.

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

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.

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.
