Another sealer analogy
I recently spun a bunch of 7" needles. Tailweighted and level sink versions. 3 woods, maple, birch and walnut. Epoxy sealed heated maple and 60/40 spar for others. I always sealed at room temp for birch and walnut. I decided to microwave the birch and walnut. 45 min in sealer. Interestingly the birch sucked in approx 7-9grams of sealer and the walnut barely increased in weight. Knowingly that, my next batch will try a lessor time with periodically checking during soak weight increase. Im ok with first batch increase since my target blank weight was somewhat lower than last year. I will experiment heating maple and sealing in spar. If i get a nice increase I would assume this penetration should hold off splitting to a point. If so, it would an easier method to the epoxy sealing. Believe me i rather use birch but i have a source of rock maple at work which is scrap when under 1 1/2" diameter. I will post with findings soon.
