I built this for use as an outdoor patio table suitable for an umbrella by eliminating the center truss below the table. Instead, I used my Kreg Jig to join the two sets of legs with 2 2x4s each set about 6 inches off center directly under table top. (See picture). I used Douglas Fir for most of this build. I also added a 1x2 cap to the bread board ends of the table top to help stabilize it against warping. I secured the table top to the frame with countersunk screws under glued wood plugs since I needed to allow a gap between boards for water drainage. I used the Varathane wood weathering product to soften the “new wood” look. I helped preserve the wood with a coat of Benjamin Moore’s clear Arborcoat. This acrylic product will allow the wood to continue to gray naturally. I recommend this as an intermediate project due to the awkwardness of joining the 45 degree angle cuts. Having a second set of hands here would have been very helpful.
