Just a quick question, will the 20 side of a rail work down the center of the plate lengthwise? I'm planning to mount the equivalent of a 2080 rail flat on it on the top side, with the plate riding the 20 side of a 2040 rail underneath. This is a manual router sled for slab flattening. Originally was just going to mount it on the 2020 plates, but they are just to small, from all the specs, it looks like putting a set of wheels on the inner holes would be perfect for running a rail down the inside. Thanks folks. Bob
