I think I’m going to cut myself another piece, seal the ends as has been suggested, and let it sit for months, year, or so, just to see what happens. I’ve got nothing to lose and I’ll learn something in the process.
I still like the idea of being able to make the seat from the tree but it’s clear that I have a good bit more to learn. I have some white oak as well that I might try after I learn a bit more.
Guess I’ll cut myself another piece and take that precaution. I knew this was risky and my lack of patience would be a problem. But the thought of using that really nice looking piece of wood was just oo much.
