The simple flat plate motor retainers ware cheep and easy to use, the down side is the threaded inserts are really close to the edges. To simplify drilling I made a 3d printed drill jig for the 38 mm retainers. Drop it into the centering ring, drill a 7/32 hole using the jig (with a piece of wood behind the centering ring!), then run a 15/32 though the hole without the jig to get a clean good diameter hole. you can always jut go to the large diamter from the start, just 'drill' the drill jig with the larger drill bit before using it.
