re: Breadboard ends

I just watched one of those woodworking shows on pbs the other day about this. The guy cut the tenons narrow so there was space between them. He really didn’t go into the why – or maybe I just missed it – but that makes sense in a movement situation. He did mention that he cut the breadboard slightly larger than the width of the table top because it was winter when he filmed it and he was prepared for expansion. He said cut it the same width in the summer because the top will have already expanded to it’s maximum size.
