Post 26 in a series describing the design and build of a dining table made from a large plank of bubinga.
With the dovetail mortises completed on the long aprons, I could move to the work on the rest of these joints. The battens are mechanically tied to the aprons using the dovetail bar mechanism, which the battens themselves are located and aligned by a pair of stub tenons, mechi. While it would be nice to use a single jig to cut both the dovetail and the stub tenon mortises, that was not so easily done in this case, so I elected to use two jigs. Here is the jig for the mechi hozo (mortises):
The critical thing when using two jigs in the same location is that the second one be able to index precisely to the first. I formed a dovetail stub piece and attached it to the underside of the jig in a centered groove:
The battens were a snug fit and required very little adjustment. The adjustment required was typically involving the set back of the male dovetail stubs on the aprons, which I had left a little fat by about 1/32″ for this very purpose:
That’s all for today. More tomorrow. Thanks for visiting the Carpentry Way. –> on to post 27
