Base for oval glass top Dinning Table.

The glass top is a 60”x40” oval, so I wanted an interesting base as it would always be visible. The construction is walnut that I resawed into 3/16×3” strips, then laminated on a form in a vacuum bag to create curved supports of about 1.25” thick. The center arched pieces supported the top at points 54” apart along the major axis of the oval with the minor axis support points about 37” wide. I was worried that the base would not support the top with weight on it as the glass weighed over 100 lbs. It turned out that the major axis supports were plenty strong but the minor axis legs needed the 1/2” diameter braces since otherwise it would only be supported by a glue joint square 3”x3” at the center of the arch. I designed the arches so that, if needed, I could put crossed braces through the center to stabilize the legs with triangle braces. It turned out the legs were more than strong enough with the small vertical supports since they were in compression. One of the great aspects of this design is that no matter where you sit around the table, the base is well inside your knees. The 5th photo is of just the base on my deck.
