Need exact measurements (preferably in mm with a caliper) of the metal shaft on a Williams Liberty Bell (or compatible machine like Grand Prix) between the match number board and the score reel pcb boards. I need these measurements so I can order a 3d printed shaft. Thanks

Don't want to just buy a unit on eBay? Or someone here probably has one kicking around.

Here's what happened. Bought a 3d printer and thought it would be cool to reproduce the shaft mentioned above. During this process, somehow I lost the original shaft. I finally got the machine working by printing the shaft and the gears via many iterations. But, with PLA filament, I don't know if it will start to wriggle lose where the square shaft inserts into the plastic circles on either end, so I found a site on the web (craftcloud) that will print this shaft with a multitude of different materials, including steel. That's why I need the measurements of the shaft, i.e., diameter of round ends, measurements of square shaft, and length. I have searched high and low for a Williams match unit and cannot find one. Other members on pinside are also searching for the match unit. If I could find one, I would get it. See picture to be sure we are talking about the correct match unit. Appreciate and help from the group. Reed

While I applaud your 3D printing efforts, I'll offer possible alternatives:

https://flippers.com/catalog_oc/ratchet-and-shaft-p-5567.html?search=7548 (if you just need the shaft)

There are actually different actuators as shown at:

so double check which one you need before you order. I suspect that the shafts are all the same.

Wow, had no idea these were available. Looks like the first link is what I want. Thank you very much Mark!

Thanks Mark G & thank you to Basset for starting this topic. I have been looking for one of these for my Triple Strike for ages. On TS it does not effect gameplay, but it has always bothered me that my match numbers didn’t rotate.
Thanks again!
