Just been tinkering in the shed. Pulled out my old 3.5 gallon pressure pot and slapped a new seal ring in it. Replaced the pressure release valve with a more suitable valve. Removed the siphon tube, changed out the gauges to vacuum gauges. Got hooked to the vacuum pump and it's pulling as I type. I might be changing my stabilization method very soon. We'll see, just hope it hold a vacuum, should though, this pot is built like a tank.
