another quick tip for the OP with those ratcheting heads
put a couple of drops of epoxy resin on the body in line with the rises on the direction selection mechanism and with the ratchet in either the ondo or undo position (your choice) use a dremel or small file to notch or remove the ridges that line up with the epoxy. This lets you set it by feel when you're using it as a hand spinner or to check it when you bump it while in use but cant see whats happening.
you can also cheat a bit and using a good elastic band wrap it around the female riser at the top and pulling it around in just the right way use it to apply pull on the selector wheel mech so that it will reset back if you happen to bump it against an adjacent part that wants to keep knocking it off the setting you want.
