Wood stabilization process....

Does anyone stabilize their own wood using the vacuum process like this?

What vacuum compressor do you use? Harbor Freight?
What resin?..... cactus juice?
What vacuum cannister? source?
Any other tips or tricks?

This process took several days....

The answer to your question will only be as detailed and specific as the question is detailed and specific. Good questions also include a sketch or a photo that illustrates your issue. (:< D)

In order;
-I do
-EBay special single-stage vacuum pump. Need a new one though, going to go with a 2 stage this time
-cactus juice
-made a chamber out of some mason jars
-I have an instructable up for other tips:

As with most things in woodworking, its a simple process that people enjoy making complicated

I need cheaper hobby

I have a setuo almost identical to that except I have a lab grade pump I bought secondhand. I also use Cactus Juice.

with regards to the vacuum pump, often wondered if you could tap the inlet port (input air filter) of a small compressor for the vacuum needs....

An air compressor probably would work, I use my refrigeration vacuum pump since I have a few sitting around, unless my son used them then who knows where he left them LOL

But if you do use an oil filled vacuum, change the oil as soon as you are done with it, the water in the mixture will get in the oil of the pump and cause corrosion, in some cases death by corrosion

For the chamber I used some Schedule 40 PVC pipe, I doubt if the foam filled pipe would stand up to it, it is amazing how stuff will collapse from atmospheric pressure during an evacuation. I have seen centrifugal chillers suck a barrel of R 11 dry and squash it like an aluminum beer can

For the lid og the chamber I used 1/4 Plexiglass and tapped a 1/4 iron pipe thread into it so I could install a 1/4 flare x 14 MIP fitting to hook the hose to, and used some sheet rubber for a gasket

My biggest obstacle was the miserable thermostat on the toaster oven, it had a 100F spread between on and off, so I added some controls and it holds now about 2F +-
