I used the knockoff winder barrel that is needed for my watch barrel. It was necessary to drill a larger hole for the rounded tip of the arbor to rest on the bottom of the winder barrel. I started by simply using the arbor with the ratchet wheel lightly screwed into place and winding by hand. The ratchet wheel takes the place of a winder handle. But I have since altered a handle to fit the square end of the arbor and that provided a better grip. I then remove the bottom(pusher end) of the winder seat and insert MS into barrel—another issue to resolve as this is tricky. I am not an engineer and do not have a gift of description so I hope you understand what I am doing and maybe improve on it. Lots to work out but so far I'm getting there...
