I designed park benches for the tennis courts in our town. 10 men and boys from our church built them. One of the boys and I built the prototype. It all worked. We built one and had 2 others ready for assembly including staining. One of the men had teak 4X4's, so we used those for the legs. I am sure they will last a long time and are very sturdy. The high school tennis coaches are going to place them around the court and apply a couple more coats of stain. I hope our church gets some publicity for this in our local paper, we will see.
