|Finished deck beams|
Once all the beams were completed I ran them through the planer on both sides. Sanded the underneath of the beam and rounded the edge slightly. I put trunnels every 10 inches by drilling 3/8" holes from the top down through the layers to mid-point of the lower layer. I then drove a 3/8" dowel with glue into the hole for extra strength. The final touch was to coat the beams with a coat or two of Tung Oil.
