I ordered a 6x20 stabilizing chamber from Turntex and a gallon of Cactus Juice to stabilize some Oak burl I found in the forest. It's an interesting process and something I had never tried before. Got a used vacuum pump from a HVAC friend and after the wood had sat in my shop attic for 9 months I started stabilizing. Following the directions Curtis provided with the vacuum chamber, I stabilized my first batch of wood and it came out very nice. I had several experienced folks tell me that Oak was not the greatest wood to stabilize because it cracked a lot and would have many occlusions and they were right. However, I am pleased with my first batch of stabilized wood.
Now for the bad news. Curtis' instructions very specifically advise not to let Cactus Juice get hotter than 85 degrees or bad things will happen. On my second batch I left my shop shut up for several hours while I did some brush hogging and when I came back to check on the process I learned very quickly why directions should be followed. The CJ had gotten over 85 and became a solid mess in the vacuum chamber. I have returned the chamber and solid mess inside it to Turntex and Curtis is hopeful he can fix the problem. Hope he can.
Lesson learned for me is that because my shop is not air conditioned I shall only stabilize in the spring, fall and winter in Arkansas when temps in the shop remain below the critical point.
If you want to stabilize your own wood, I highly recommend Turntex and Cactus Juice.
