Planned: Key and setscrew for each of the 4 plastic gears.
We expected gears as plastic with a metal bushing in the hub large enough to bore & modify. Well, the gears we got in time for ship date were different from plan, so we had to improvise a bit.
Actual:
- The Mod .7 metric gear (meshes with Bosch drill motor) is all plastic, so it has just a key with no set screw. This worked out fine, with the gear hub covered at both faces, the key is captured & can't come out the end of the hub.
- The other 3 plastic gears, I think 32 DP, (meshes with Fischer Price motor) are mixed - have either key and setscrew, or just setscrew.
