Hi, Fred.I will implement most of the suggestions pretty soon, especially the safety related one and post photos.
So you built them to 36", which must've been good for you, and that raised section of the garage makes them too tall?The Duckboards were needed due to my first mistake. You can't see from the photos, but the workbench is on top of a raised floor. The floor is raised about 2" for the the back 3' of the garage, the exact size of the bench.
I read that the bench should be 36" high, so that is the way I built it. Standing on the floor in front of the bench, the effective height is 38" .. uncomfortable for me.
