Got some results,
First I cut the wood into 3/4 x 3/4 x 6" blanks and baked at 160 for about 2 hours. It drew some sap out but after shaving it off, the wood still felt sappy.
The next day I baked it at 250f for about 6 hours. That drew a LOT of sap out and caramelized it as a very hard surface on the wood. That gave me an Idea.
I then drilled and turned the blank down to the shape I wanted and baked it again all day at 300f. That caramelized what sap was left in the wood and made a very nice finish surface. I then sanded smooth to about 3K and then buffed with a dry rag. I haven't tried using polish yet, but the caramelized sap makes a really hard coating. almost like CA.
There are some issues and flaws with this test blank, so I am going to try again. This time I will turn the wood down first so I have more sap to caramelize on the surface. I think I drew to much sap out before turning last time so it didn't caramelize evenly after turning.
There is no CA or any other polish/finish on the wood, just the caramelized sap from baking. (for a 2mm pencil)
