question about back graduations

[Ken McKay]

Haven't you ever watched the New Yankee Workshop Ken?

Naam is always gluing things that way! " ...I only apply glue to the center of the breadboard ends to allow for expansion and contraction of the tabletop." If you don't believe me, a video is available which includes a measured draring.

Eric was just applying this concept a little differently, by applying spots of glue to the brace so the back (underneath the brace) could expand in between those spots. There is no glue drips outside the braces. Now he is admitting it is not advisable.
