This is another post in a series on the design and construction of a dining table patterned on a Ming Dynasty piece. I am trying to work within Chinese traditional work practices, in terms of a minimal use of glue and pegs, and no lathe-turned pieces.
I keep revisiting the original drawing and tweaking details here and there. Decisions involving outcomes which affect aesthetics are made in conference with the client, while more minor structural detail changes and other technical nuance shifts I tend to do on what one could call an ‘executive’ basis.
I thought I’d share a couple of those minor changes. First of all, in order to reduce the weight of the table where I can, while retaining strength, I have re-designed the central beam somewhat:
The beam now has a slight lift in the middle by removing a portion of the underside, and a series of hollows are now incorporated. These hollows allow me to shave weight while retaining the structural logic of the ‘I‘-beam. In the middle of the beam between hollows a 1/2″ web is retained.
I also revised the connection between the giant’s arm braces and the central rib, to improve the strength of the connection and clean up the appearance from how I had it configured earlier:
I have done some more cutting work on the legs. First I spent about half a day making a jig to hold the legs on a diagonal orientation:
This jig allows me to cut a slot into the leg on a diagonal, first by using a Forstener bit in a drill press and then using a router. The top cover on the jig is removed in the next photo:
