Great info, thanks. Since I am starting with a traditional woodworking bench, I cannot screw anything in from the bottom. It is 18" of solid maple. The casters and height adjustment are already built in, so I just need an overlay. I am leaning toward plate glass with a metal sheet on it for using magnets (T-pins were not issed during my break from. Modeling). I figure it is easy to clean, dead flat and smooth.

When I'm do e with the the basics I'll throw a pick or to up. <br type="_moz" />
