The table isn’t in the sun, but it is about 5 ft from a heat register though. I thought that would be far enough away to avoid any issues. The lumber was in my shop for about 2 months before I worked it and it is kiln dried, but I never put any MM on it. I’m beginning to think that it was improperly dried from the supplier, and now that humidity is 30% in my house it’s causing issues. It might be time to invest in a MM.
Almost every board is now showing at least some cracking along the endgrain at the medular rays.
