I have two 6" inside diameter x 12" tall stabilizing chambers for sale. These were built by me as, when I was building some chambers for myself, the most economical way to purchase the 6" clear PVC was in a 5' length, which was longer than what I needed. The one pictured is ready to go, the other one looks exactly the same and will be ready to go about the middle of next week - I'm waiting on delivery of a vacuum gauge and a couple more fittings to finish up the other lid. The chambers are made with Schedule 40 Clear PVC, the bottoms are Schedule 40 PVC caps, and the lids are made from 1" thick PVC w/ a rubber gasket. The bottoms of these are domed, so you will need to build yourself a holder/stand to hold the chamber upright. Each chamber is $165 + shipping. (A TurnTex chamber of the same size is $210 with a lead time of 4 to 6 weeks - these can ship this week.) I imagine UPS or FedEx will probably be the best way to ship. @Mike Hill has first dibs since he had expressed interest previously. (Vacuum gauge isn't reading 0 because there is a rubber nipple that needs to be cut off to vent the gauge and I haven't cut it so the oil doesn't leak out and run everywhere during shipping. It will zero out once the nipple has been cut.) Have also made a disc to help hold down the blanks in the chamber. It is made from the same PVC as the lid, just resawn to be thinner. It is not enough weight to hold down the blanks so you will need to find something on your own to add weight to hold the blanks down to keep them from floating. I have a bunch of 3/4"-16 tpi nuts that I use for weights. I asked Curtis a while ago if there were any metals that would have a reaction with Cactus Juice and he said you can use any metal you want for the weight. While not pictured, each chamber will include about 5 or 6 feet of vacuum line with a quick connect fitting on the other end for attaching to your vacuum pump. To hook it up to your vacuum pump, you will need one of these fittings to go on the pump and then one of these fittings to go on that: If you need a vacuum pump, I have and recommend one of these.
