After a brief flirtation with the Harbor Freight workbench, I've decided to build my own. The plan that I like calls for a top made from 3/4" plywood. But I wondered about using a kitchen butcherblock countertop for the top. There's a salvage place near me, and if I found a butcherblock top that would work, would that be worth considering? Or are kitchen countertops made in such a way that it wouldn't really be sufficient?
