ROV torpedo idea

[CS]

PVC Arsenal 17, hmm would of thought that the cartiage would of floated, since I didnt think the metal "weighed" that much. Possibly cover the hole with some tape or something?

They do sink full of air without ANY of it escaping.


Anyway, I've ran into some awesome luck with this project. For the piercing bolt, I chose a 1/2" metal conduit coupling with a 1/2" brass plug screwed into it. I will drill out the plug and put in a nail. This coupling fits PERFECTLY in 1" PVC. The barrel is 3/4" PVC. It is removable using a male adapter which happens to be a PERFECT fit for 12 grams.

So, the bolt section is 1" fittings with a reducing female that has 3/4" threads for the barrel. Since I have perfect fits for the bolt & cartridge, allignment is also awesome which helps a lot with the piercing.
