California Air Tools Pressure Pot.

Figure I can cast some of the spalted pieces laying around the shop. Smiley


Question... if I have a piece of wood that isn't quite dry, can the moisture be pulled out with the pressure pot?

Not sure if that is even possible but no harm asking.

Not even close to being an expert on casting, but.... My experience is no. I use only Alumilite because that is what I started with and no other reason. Alumilite is very unfriendly to moisture.

I weigh each piece then put it in the oven at about 220f. About every hour I weigh each piece again. When the piece stops losing weight it is dry and ready for casting.

You say you have spalted pieces. Do you want to cast them or stabilize them? Spalted wood usually needs to be stabilized which is a different process from casting.

Casting is usually done on hard or solid woods using pressure which removes the air bubbles from the casting resin. You might use casting to fill large voids in a piece of wood that has been stabilized prior to casting.

Stabilizing is usually done on soft/punky woods using a vacuum chamber. Stabilizing also needs to have the wood dried first. The vacuum removes the air from the wood and then when the vacuum is released the voids are filled with the stabilizing resin. Stabilizing will fill only tiny voids.

Well.. I do have one piece that is seriously spalted to the point of getting punky.  Seems no amount of CA helps.

Sad because it has a nice green patch in it and would look neat.

A vacuum chamber might  be nice to get as well!! Smiley

Most of the spalted pieces I was thinking using are pretty solid.  Pieces left over from cutting a blank from a larger hunk.

Thanks for your input.

With Alumilite, wood MUST be DRY. Otherwise you will get foam. Been there, done that. West system is a little more forgiving. But not much.

Use catus juice for stabilizing. It requires an oven to cure it. You can get a plexiglass sheet and make a vacuum cover for the pressure pot. A couple of valves & vacuum gauge.  Multimedia File Viewing and Clickable Links are available for Registered Members only!!  You need to Login or Register
