This is the perfect workbench for my garage here in South Florida. I modified the plans using 2x4 actual dimensions so that the outside dimensions were 60" wide x 40" height x 30" deep. I designed it for my husband and he is 6'4" so I wanted it to be taller for him. I used 3 sheets of plywood (3/4" thick each layer) for the top and it is super sturdy. For the bottom shelf, I left one 2x4 off so that it wouldn't hit our shins while standing at the front. I was concerned at first that the wider bench (60") may need an additional bottom shelf support in the middle. It did not need this extra support. The shelf can hold a lot of weight with no concern. See all the tools that are on that shelf in my pic. Thank you Ana White for these great plans - it was my first workbench that I have built. I am looking forward to more woodworking projects.
