Hi Brian, There are two problems with using threaded rod for plate setting. The first is that you are dealing with a machine thread designed to hold best in metal. The second is that you may not have enough clearance under the plate for the nut and how are you going to adjust it from above the plate. The real beauty of Coleman's system is that you _can_ adjust the bearing after the plate is in. I chose this method because I do not have a method of lifting out the plate by myself so for me it is a one shot situation. Consider the bolts that go through the soundboard to the structural member below. It has wood threads at the bottom and machine threads at the top and they are adjustable from underneath the plate. Jim Coleman Jr.'s bolts fulfill those needs admirably. Newton
