I am cheating a bit here, as I had always wanted a nice laminated maple top workbench, but did not want to go to the expense and hassle of putting one together. Well, when I went to a local school auction, I picked up a 50" x 76" maple workbench top with 4 clamps attached, and now I'm just going to be building the base for my new workbench.
This thing weighs about 250 lbs I would estimate, and I'll be using a base design similar to the fancy curly maple bench in one of the recent wood rags on the market (I don't remember which one, but my FIL picked it up when he saw my bench top). It's basically going to be four 4x4 oak legs with an apron at the top and bottom to make a cabinet. Unfortunately, the article does not indicate how the top is attached. I'm inclined to attach it using pocket screws, but noticed that some people have suggested that wood movement on the top may be an issue.
Any suggestions on how to attach the top would be appreciated.
