I've got a 24" x 36" x 2.5" edgegrain top finally glued up, 1/3 is cherry w/ walnut and sepele. The cherry is quite abit lighter, I know that the sun will darken it but my question is- If I place this in the sunlight to darken the cherry would there be a possibility of the top bowing/warping from the heat of 98-100 sunlight, anyone have any experience with tanning butcher blocks ?
