If you don't wish to follow the directions by owner of Cactus Juice for stabilizing on the link provided I'd suggest using K&G to stabilize wood. When I first started using Cactus Juice I had problems until I talked with owner of Cactus Juice on phone. After following his directions Cactus Juice works good on suitable wood. Most woods that have a specific gravity <0.3 or so will home stabilize just fine. Once the specific gravity gets above 0.6 it's more of an "iffy" proposition. A lot of determining proper wood is testing yourself.
To get wood really dry in 24 hrs you need to hold temp above 200F. Since you're really worried about safety, put toaster oven outside with an extension cord. Perhaps put a metal tub over toaster to protect from elements, but don't reduce air flow or the oven might get too hot and actually cause a problem.
