Chris.
I stabilized wood all the time for woodturning.
1. You need a thick wall pot, but I've built a vacuum chamber from pvc pipe because the pot I have is too short.
A smooth rim is necessary for the lid to seal tight.
2. You need a vacuum. Not a pressure pot.
Those are all over Amazon and eBay. I found mine off Facebook marketplace.
You can actually pick up the whole set up from amazon.
3. You need stabilizing resin. I use cactus juice brand. Always had great results.
4. Wood needs to be DRY or you resin will crystallize on the outside when you bake it.
5. Buy a cheap baking oven from Wal-Mart. It will get ruined as resin will drip everywhere. Buy a thermostat for the oven because the dial is never accurate.
Buy lots of foil sheets.
Get latex gloves. That stuff is not toxic or irritant, but is slimy, and everything somehow gets covered it in
Washes with soap and water.
The resin can be under vacuum for hours, if not overnight.
If you are double dying the resin, the process is a couple days long, to be honest.
It's a fun yet not always necessary process. I turn a lot of shaving brushes (that's what sells the most) so I stabilize the wood for water resistance, but have turned some burl and punky wood without stabilizing it.
Let me know if you have any questions.
