I got this information from this forum in the first place, but can't find the thread. I honestly looked for it. Anyhoo if you follow this link it will describe the Vacuum Kiln. I have most of the material to build it, but have been a little slow getting going this spring.

Another note, I e-mailed Lynn Diel, and got a response from him quite quickly. The diagram dosen't show an inline water filter, between the tank and the vacuum pump. He said to put one in to protect the pump and drain off the water. Got one on E Bay for $35. It looks like the one I used to have on my air compressor when I operated a garage. Same arrangement I believe.
