Well just putting my first breadboard style tabletop together and used my router and a straight bit to cut my tenon, the questions are how much room do you think I should give the mortise for expansion? And do you think the tenon should be left full length as shown in the photo, or broken down into multiple tenons?

I believe for wood movement they figure 1/16 per 12” of width on average, and multiple tenons are stronger then one large one.

Pjones,I was looking for that link to post but you beat me to it, I think it explains very well how simple it can be to to allow for wood movement in BB design.

I had to learn the hard way myself, made a small coffee table with a nice BB style top, 3 months late we heard a loud crack coming from out living room, it was my coffee table top with a 1/4” crack right in the middle of it, but I left it as a reminder on what not to do,plus, the crack almost disappear in Summer months. .
