I cannot find this answer anywhere, hopefully you guys can help. I am planning to build a heavy, overbuilt, Paulk style workbench. I would like to know how thick can the top be and the Festool clamps will still be able to thread into the 3/4 holes. For what I'm planning it would be great to use a double layer of 3/4 for the top. I'm not sure if the 90* bend in the clamps can make the turn through 1.5" of plywood though.
