I should have done that here. The main reason I didn't is that on the first slab, I almost didn't get the dowels out again, even without glue. In retrospect, I should have gotten new dowels or microwaved them for a few seconds to shrink them.
My dad has success in a custom shop for having an eye for color, tone, and grain while building. He also has endless patience for blending wax sticks to make pun nail holes etc. disappear. The hidden side of full time cabinet work is how many other trades will leave you needing to make those kind of field repairs for dings etc. The building is only one part.
