I found some 1x12 that was a nice cross section cut to make a small cupboard with (by hand of course). I was able to cut and use quarter sawn pieces for everything but one of the boards had some pith running right down the center and I thought it might make a good door since it can be centered. The pith doesn’t run through both sides of the board - just one face - is there a way to seal it or make it stable so that it would function as a door to the little cupboard I’m building or should I just use another section with no pith running through it?
