Back in the summer, I made a Stickley trestle table with a 1.5 inch top, 40” x 55” kiln dried red oak. Now that winter has come and humidity is down in the house, one end of the top is cracking in multiple places, with one being fairly substantial. I have attached the top with multiple Z clips and there are no breadboard ends. There’s literally nothing preventing the top from moving the way it wants to. What would cause a crack in a tabletop that has the freedom to move?
There is on large crack and multiple other smaller ones along the medulary rays. They were definitely not there before I finished the project.
Any thoughts??
