lexAN IS COOL BUT IT MIGHT EXPLODE IF OVER PRESSURED. TRY PLASTIC GAS PIPE THE ORANGE STUFF, IT ONLY SPLITS DOES NOT EXPLODE. AND PVC WATER PIPE IS A BAD IDEA TOO!!!!

Someone should start producing these so that people who do not have the time or inclination to build them can purchase for use with our kits.

KJ sent me some pictures of the sensor pressure pot he has built for several people.. If there is enough demand he would consider making them...

I'll post something shortly..

Here is a pot I built out of an OMS 660 canister and an analyzer flow meter to measure all three cells at once. It hooks directly to the Megalodon head, but could be made to connect to any head with the appropriate connectors. I installed a Shrader valve behind the pressure gauge. Just hold the Shrader valve open and purge until the handsets read 1.0, then release the valve. When the pressure builds to 9, 15, or whatever psi you wish, turn off the flow meter and disconnect the LP inflator hose. It will hold the pressure as long as you need. When you want to depressurize the pot, simply open the flow meter so the pot slowly depressurizes (and you won't bend the cells). I ran this by an engineer friend of mine, and he was fairly confident the canister would safety withstand repeated pressurizing to 15 psi. I had the 660 canister and flow meter laying around, so with the other parts I purchased it cost me $15 from parts available at Grainger and computer supply houses. Cheap and easy. No Rube Goldberg here.

I have to say that Ron's DEMA video is what inspired me to build the 660 test pot. If anyone's willing to spend $300 on a test pot, I'll gladly sell you my kit for $275!
