I am building a sofa table out of 3/4" walnut using mortise and tenon
for the back and side aprons.
The stretchers connecting the legs on the left and right sides (front
to back) lower
will also use mortise and tenon joinery.
I plan on using a piece of 3/4" walnut approximately 10" wide by 45"
to act as both a lower shelf and to act as a center stretcher
the two lower leg stretchers.
There will be a cleat on the interior of both the left and right lower
which will support the shelf.
I am not planning on placing anything heavy on the shelf but I am
concerned about possible sag.
I thought about gluing lips on the front and back of the shelf which
would span the
entire length. I know that this is effective on bookshelves but I
this idea since I want the shelf thickness to equal the table top
Since the bottom of the lower shelf will be about 7" above the floor
and not readily visible I thought about
glueing two 3/4" runners to the shelf the same length as the lower
shelf on either side of the cleats
supporting the shelf.
milling two shallow dadoes about 1/4 deep by 3/8 wide and inserting
splines which would
sit about 1/2" proud of the bottom surface
Any one have any comments on this approach?
Any one see any problems?
All the best
