The pear HF is 7.5 X 7 and finished with 4 coats of min wax wipe on gloss poly. As the first finish coat was drying 2 large cracks opened up at the mouth. I let it sit for a few days waiting for the cracks to do their thing so I could do my thing. I filled the 2 large cracks with saved sawdust and CA, sanded flush and finished applying the poly. After curing for a week or so I noticed the knot had gone crazy! Big swirls formed all around it like ripples in a pond. The knot did not crack but the now sunken in knot had deep flowing crevases around it.... Guess I better let this pear wood sit a bit longer before doing end grain forms...Bill..
