I'm planning to build a Garden Arbor/swing out of 4x4's and 2x6's. I would like to chamfer the 4x4's and "ease" the edges of 2x6's. I realize the "easiest" way would be with a router but, don't have the bits. What would you suggest? I have table saw, jig saw, and planes. Arbor will be 88" high and 76" wide.
