Yeah, the gears on these old rigs usually have more than one purpose. The pre‑war engineers liked to hide warnings in the alignments. If the teeth are all even and the pattern repeats, it’s probably a checksum. But if you see a line of uneven teeth, that’s a warning or a lock. Keep a close eye. These machines are stubborn—talk to them like you would a friend. If it feels like it’s listening, maybe it’s trying to tell you something. Otherwise, just work the sequence, and it’ll do its job.
