DIY Exposure unit plans inc. vacuum top

looks like door liner for cars, try an autobody shop. Valves you get at a truck tire shop or cut off a big innertube.

nice system, what pump type you used ?

[Earl K]

Hey, we use a vacuum pump from a refrigerator, a bit slow... but free.
The blanket is 2mm natural rubber, really sturdy and the cheapest option we found in the size we needed.

wasn't some dude on here talking about septic tank liner for the vacuum top. i believe he said it was 'the shit'! badumbum!

[Manny Green]

Can you tell me the type of Black lights you would suggest work best.

I was the dude using the septic tank liner for the top of mine. Here's the thread: DIY Exposure Unit Vacuum Top for under 20 bucks And it was very rubbery--probably not the sort of thing that you'd want breaking during it's intended use, you know?
