Vaccuum sealing

[derf]

ok
the one thing that could be a problem is ; when you draw a vacuum on something you lower the flash point .... might not be a problem , but i'd do it outside just in case.
was thinking about it myself .......

then you are doing good.
Try alaskan yellow cedar, it's heavier, or basswood.

I will , right now I've got some maple plugs turned .

I also heard of people also using modified pressure cookers to impregnate the wood with various sealers but don't remember the rest of the details.

I hav'nt thought it all the way thru but is'nt a vacuum or lower atmospheric pressure the opposite of what you want, after all they don't vacuum treat lumber.
If you are trying to achieve maximum penetration, I would try and minimize the water content of the wood by drying it further than air dry. You could use a food dehydrator to accomplish that and then use a pressure vessel of some type to treat the wood with sealer.
I think i just thought it thru.

just soak the wood longer in your sealer...24 hrs.. did you now that by kiln drying wood it kill's the cell's in the wood..collapes them to the point where they can't return to their normal oval shape..once collapsed the wood is well on the way to dieing[rotting]...

By drawing a vaccuum in the jar , all air is drawn out of the wood and is then replaced by sealant . A person can achieve the same penetration in one or two hours by drawing a vaccuum as it would take months to achieve just by submersion . The moment the vaccuum is drawn , you can see the air bubbles pour out of the wood .
When the bubbles stop , I remove the plugs , wipe them down and let them dry . The addition of naptha as a thinner also allows for fast drying .
I got the idea of sealing plugs this way from a shop teacher I had in highschool , ( about a hundred years ago) , who had us use this technique to waterproof wooden handles using mineral oil ,which we attatched to metal spatula blades , (required project to pass the class) .
p.s. I still have the spatula

KW, how long are you drying them before painting?
