I started this project in June, but it’s been sitting in the garage waiting for me, while I have been waiting for cooler weather. It was somewhat cooler last week, so I pulled it out to work on it.
Rip the plywood on the table saw
I ripped it to size and ran one side of each piece through the table saw with the blade set at a 45 degree angle. (the angled part is laying on the driveway)
Clamp using a 4x4 to keep corner square
This was done the same way I do corner benches. One side is ½ inch shorter than the other side to allow for them to end up the same width. I have it glued and clamped on each end using a 4x4 to keep it “square”.
