I am replacing some pressure treated boards of my fence that keep the top lattice in place. Home Depot sells the wood but not with the channel/groove. Tart lumber sells the wood and will make the cut for a premium price. Any suggestion for a different local vendor that I can reasonably purchase the cut wood from? or Does anyone have the tools and ability to make a dado/channel cut in seven 8ft pieces of 2x4 pressure treated lumber?
