Although I have done quite a few furniture building projects, I am "breaking new ground" in a number of ways on this project: 1st dining room table; 1st time to use SU as a design tool, and 1st time using loose tenon joinery.
Although I would appreciate comments on any of these, my main question is on the design itself. Based on my research so far, I have left 16 inches of knee room at the ends, which seems fine until I insert the two 12 inch leaves. This gives me an 84 inch table with a 34 inch footprint for the trestle assembly, about 25 inches on each end, which looks in the drawing like it would be likely to tip toward the end if anyone leaned on it. Granted, the table and trestle assembly are pretty heavy, since I plan to use maple, but would appreciate any thoughts.
I would also appreciate any comments on the use of loose tenon joinery. I've had the urge to use it based on a video I saw on chair making. Seems like if it's strong enuf for a chair, it would also be strong enuf for a table.
Finally, as to the drawing itself, it isn't finished (no tenons in the mortises, e.g.) and I plan to do some rounding off of sharp corners, but I think it is getting close to being what I want. Comments and improvements are welcome.
