I'm casting some "worthless" wood with alumilite and after curing I have lots of bubbles where the wood and acrylic meet. Is this because the wood is not stabilized or is there something else going on?
Im using a pressure potAre you using a pressure pot or vacuum chamber?
This is very old wood - very old! certain there is no moisture.
When i work with non stab. wood - at the first i threat the wood surface, that will contact resin, with small amount of resin with help of brush. It soaking and sealing the surface. After curing that layer (at least for 50-70%) - make the main cast, as usual. Also a good idea to dry your wood, as were suggested many times earlier. You can control the dry process by scales. Measure weight of you wood before drying process - write the value on paper. And make weighing with some interval - 1 hour for example. Write value for each measurement and compare with previous, until the weigh stop decline, or decline just a bit - the wood is almost dry. Let it cool down and go further.I'm casting some "worthless" wood with alumilite and after curing I have lots of bubbles where the wood and acrylic meet.
