I’m building a paneled blanket chest (redwood panels, cherry frames), and took my first stab at breadboard ends for the lid. The lid is about 26” front-to-back; I used a single mortise and tenon, glued it for about 6-8” in the middle (with a dowel glued in place too), and put dowels through elongated holes in the tenon on each end.
Unfortunately, after glue-up I discovered that either my tenons got narrower or my mortises got wider towards one end of each of the caps, meaning if you grab the cap at that end you can feel a slight but noticeable up-and-down wobble – see pic:
I’m trying to fix this and I’ve come up with a few ideas, but I’m not sure whether any are fantastic (or even viable):
(1) Shoot a nail or two at an angle through the end of the cap into the panel like a pocket screw, to hold vertical alignment while hopefully being flexible enough to withstand seasonal movement (at least for a little while).
(2) Drill shallow counterbores on the underside of the end cap and the panel, such that I can use figure-8 desk fasteners to hold alignment while allowing for movement (e.g. http://www.woodcraft.com/Product/159303/Desk-Top-Fig-8-Fastener-10p.aspx?).
(3) Drill/route an elongated hole in the end cap sufficient to screw through the cap into the panel (with the screw floating in the elongated hole), counterboring and plugging the hole to hide the screw.
(4) Work some glue into the joint near the wobble and hope for the best (not really).
I’m leaning towards either 1 or 2, since 3 would introduce many opportunities for error.
Anyone have any thoughts or suggestions?
