Here is a quick build thread of my work bench
http://www.rcuniverse.com/forum/m_10...m.htm#10732121 I had the wood on had so I hand no additional expense. The ply was a "cheap" sheathing grade with lots of knot holes and such. I don't know if there is such a thing as cheap plywood.[&:] That didn't matter as I was putting a replaceable working surface on it anyway. If I were to do it again I would not make it as wide. It's hard to reach to the back to grab anything. If it were standing in the middle of the floor it would be a different story. Other than the width I would not change a thing. The bottom shelf makes it plenty ridged so sanding and moving stuff around does not cause it to shake or wobble. It is "belly button" high at about 42 inches. This way I can stand or sit on a tall chair or bar stool and work. It took a whole sheet of ply to build the frame and legs and another sheet for the top. The 1/4 laun ply is fairly cheap. Attach the bottom first. It is still pretty flexible at this point so make sure it is level and flat in all directions before screwing the top on. After the top is on it is completely ridged.
