To answer your question a bit more, The ONLY home stabilizing method that actually works is using Cactus Juice or a
similar resin. You'll need a vacuum pump something along these lines:
https://www.amazon.com/dp/B01N6IOBWF ($50 to $60 shipped) and a vacuum chamber, perhaps your canner might work, but you really NEED to be able to see the resin and wood to determine when the air is expelled from wood and ready for resin to start soaking in. Also, when you start the vacuum there will be foaming and you NEED to be able to see that foaming action to prevent the resin from getting pulled into the vacuum pump.
Results of this home stabilizing? All depends on the type of wood. An open pore wood like a spalted wood works great. You'll get full penetration of resin and the finished block will either sink in water or float just level with water. BUT - denser woods like Black Walnut and similar just don't work very good at all. Better left to K&G.
Cost? Well, not as cheap as we'd like to think. Not including cost of pump and chamber, just the resin costs a block is going to run in the $3 to $4 per 1"X2"X5" block of wood (provided the wood is free). I just finished some blocks of spalted maple for a buddy. He sent me 1/2 gal of Cactus Juice ($65 plus shipping) and 2 bottles of dye - total cost around $80 or so shipped. After finished 20 blocks I had less than an inch of resin left, not enough to do anything with. That's $4/block. Pretty darn close to what you'll spend with K&G from what I understand.
"IF" you can purchase resin by the 5 gal batch you might save a bit of money doing it yourself and have a good finished product - PROVIDED you choose an open pore wood for full penetration. From what I can tell dyed wood, the dye is the same color in the center of the block as on the outside which says it's full penetration. This is for an open pore wood.
By the time I paid for my vacuum pump, jurying rigging a vacuum chamber, buying resin, paying for learning curve I could have shipped all my wood to K&G and came out less expensive. BUT - I had fun learning.
Good luck and have fun.
