ROV Hull Components – Part 2
Love it when the bits and pieces start coming together. Not so much when water leaks inside. It's amazing what 2000 psi or the equivalent of 4300 feet of seawater will do. Stuff will leak that look perfectly watertight.

DIY Line Boring Tool
To get a really good O-Ring seal you need a close fit and Schedule 40 pipe can be out of round by as much as 20 thousandths of an inch ( 1/2 mm ). A line boring tool will cut the pipe nearly perfectly round and can face off the end as well.

ROV Hyperbaric Test Chamber- Part 4
Every foot of seawater adds about .433 psi of pressure. So to build an ROV that operates at 3000 feet or 1300 psi we need to be able to test it to at least 1600 psi which is the the equivalent of 3700 ft.
