We made these spur gear adapters in early 2023 for use on the HackFab Mini Pulling Sled. A few people have asked us to offer these as a standalone part to be used on custom builds.
It features a 1/4" bore for common D-shafting used in pullers and our pulling sleds. Includes m4 set screws and m3x10 button head screws to secure the spur to the hub. It fits common Kimbrough spur gears which are available in multiple pitch and tooth options (not included).
Includes:
1x Spur Gear Hub w/ set screws and spur mounting screws
Shown with spur mounted as example only.
