Hi Eric, the type is for the 5" g 9F. and is of the ball and wedge, clutch drive. I have made several,, they run but are unreliable in a short time, either slipping and no delivery, or jamming up. so I am going back to ratchet and pawl.. you can see one being built on utube,, on account. No23mk2. part 66, 67, & 68 john

Hi John Working in industry I worked on machines that had a sprag clutch fitted. They come in all sizes with the same dimensions as a Ball Bearing. possibly one of the very small ones would fit the bill. Took a peek at you tube

Not a good idea to make the outer in  any old steel it will FAIL even in a short time. The whole thing needs to be made from hardenable steel and properly hardened and tempered. The units I worked on had given thousands of hours service in harsh conditions.

I have made a couple according to the drawing by S. Purinton in ME. It's just a wound spring round a 1/4 shaft and another attached to the arm. The spring grips one way and releases in the other direction. Works very well and costs next to nothing.
