Well made a lot of sawdust today,not perfect but I think it will workout.I had a bit of trouble cutting the groves they were not consistent so I switched to a blade on the saw that was a little thicker as it looked like the blade was flexing while cutting.I also had to trim the pieces closest to the box sides for it to fit under the L shaped strip,other than that I am happy that I am about half done ,next I plan on loosely putting in all the bolts to drill the holes then take it all out and I plan on putting some deck stain on all sides.i was going to put the por 15 paint and stain on top but now I don’t want to cover the wood in black .
