A friend of mine needed some flanges to mount antique photographic lenses to lens boards. The small lens needed a .5mm thread up to a shoulder. I ended up making it in two pieces. I threaded a cylinder and turned it down half way to press fit into the larger plate. I've never done a press fit before but it worked great.
