I just built a vacuum chamber for stabilizing wood handle scales. Picked up some scraps from a local plastics manufacturer/distributor - 3"x15" clear cylinder & two 1/2" nylon discs - and also grabbed a brake bleeding hand pump from good 'ol Hazard Fraught for ~ $40 altogether. I saw that PC Rot Terminator 50% off at local Fleet Farm.
I couldn't find anything online about using it as a vacuum stabilizing resin, so I'm testing it myself.
I ran 3 vacuum cycles over a two hour period, holding at 25 in. Hg. No indication thus far that it hasn't worked, but I can't machine or sand the sample wood piece (small mahogany block, no rot or burl/figure of any kind) until it's fully cured, which is supposed to be ~1 week.
