I finally finished the bar. The wood was perfect and we are very pleased with the results. We are really glad we went with wood vs granite for the bar top. Your tips on joining the boards and cutting the miter joint were very helpful. I did a few test runs and it turned out well. I ended up staining it with an oil based stain (mixed mahogany and walnut) and then finished it with multiple coats of waterlox. I still have a few details to finish (foot rail, etc) but I’ve attached a few photos of the finished bar top as promised. Thanks for your help!
