      Hi Ray,
      The current 2" focuser holder already has 3 screw holes for thumb screw (120 degree apart)

      we can provide an extra thumb screws at your request.

      all you need is inform me the shipping address and pay for air mail shipping fee (around $5)
      we ship from Taiwan.

      Thank you

      William

The one in the 1.25" adapter is a smaller thread, and longer thumbscrew so you couldn't just hijack that one. I think if you wanted one to replace the set screw you would have to ask WO, or simply bring one into Lowes, Home Depot, etc and match it up. They sell all sorts of those types of things in metric and english threads, and they have a board to try it in that tells you the correct thread size. Probably costs about $3.
