<div style="color: rgb(0, 0, 0); font-family: HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 19px; font-style: normal; background-color: transparent;">If the acrylic has known properties at "X" thickness, is there still a need to test? Is it the material itself that needs testing, the seal, or frame?, I'm not clear here.</div>

The chamber is built entirely from scrap in my shop. I tested the first window to 500psi. Yes I was nervous :_) The top ring is a 1in thick window frame I had from a previous project. The side of the chamber is 1/4 flat bar bent around and the base is 3/4in plate. I machined an o-ring groove in the base that bolts to a 5/8 disk left over from building my hatch. I also had to machine the inside of the window frame again after welding it together. The window sits on a gasket and is bolted as if it were on the sub.</span></div>

<div>I was considering doing the same thing, fabricating a test pot to take one to failure just out of curiosity and piece of mind as well as test the rest to 600’ before installing them but figured it might me costly to do, so kind of gave up the idea. Let us know your design with any pictures you may have of it and an idea or your cost outlay if you don’t mind and would still like to do it if feasible. I cringe at the idea of a port light failure on the sub when testing and have to reel in a real heavy object full of sea water from 600’!! Good luck and let us know how it went.</div>

<div>Back in my diving days our company retested a couple of deck chambers and they filled them completely with water leaving no air at all so if it ruptured, there would be little or no bang. If you are testing it to failure then I guess you would still need some air on the LP side so you are back to an air gap. Get a long hose with the valve on your end and stand outside the building and peek around the corner. </div>
