I see a lot about using Cactus juice to stabilize small items, like pen blanks. But I can find very little on using it with say a 7" bowl blank or a chunky vase blank. Anyone done this? How effective is it with large pieces of very punky wood? Also, how much bubbling can one expect from items of this size/makeup in a vacuum chamber? I also suspect oven curing time would need to be longer. I have some beautiful but very punky apple root that I'd like to save, if possible. I'm trying to decide if it's worth it to invest in a vacuum/cactus juice system.
