DIY Video Housing a success...

[cjfox]

I actually have built several housings that work fine, this one was the first to burst. I did have the inside of the cap reinforced with a cross made of acrylic, and on another housing I have, this works fine to 130fsw with a switch but no cable glands. I am guessing the addition of holes for the cable glands weakened the piece just enough to let go. I am currently building another end cap of 1/2 inch acrylic.

cjfox: What thickness of acrylic imploded? What was the diameter of the piece?

It was a standard 6" PVC sewer pipe end cap with a couple of 1/2 " acrylic cross pieces epoxied in for reinforcement. I have a light cannon with the same end piece that works fine, but as the previous post, the holes for the cable glands must have weakened this one.

OK so i just finished my 2nd housing.. worked out all the bugs on the first one. It worked great so the 2nd should also... Well test dive # 1, I rolled of the side of the boat with it in my hand pushed up against my chest ( for support).. kerplunk in i went looked up to make sure i wasnt sinking and bobed up to the surface.. woohoo all is well , I looked in no watter.. got situated turned around to head away from boat and underwater when>>> SNAP off cam one of the handles.......... AWWW im bummed. ok back to the drawing board. Next time i need to better afix my handles... oh well no harm done..lol I used PVC glue to glue a threaded 45degree coupler to the main housing. maybe this time ill try epoxy.. just thought Id tell ya all a funny storie.

This is why we test first, isn't it? Glad no harm was done. Keep us posted.

McMaster-Carr has a full line. Or just type o-ring into Google.

Yeah I looked at mcmaster-carr but i couldn't figure out exactly what size i need. Is there some simple way of determining the size for 6" pipe. I figure it should be a little bit bigger than 6" but im just not sure how much bigger.

Ah, a different question entirely. Here is some information on sizing o-ring glands to give you an idea of how much larger the gland should be than the o-ring itself. If you're picking the o-ring to fit the gland, then work it backwards. I don't know the diameter of 6" PVC pipe (maybe 6-1/2"?). Depending on how you make your gland, you'll have to decide the size for yourself.

[OK, I had a nice table here, but the formatting got garbled. How does one insert a table?]

Take a look at this link.

I used an O-ring size #439. It fit around the OD of 6" PVC pipe.
