I'm hoping Dave's pictures might give me an idea as to why the ratchet isn't ratcheting. At the moment, when I engage the pin, the gear turns and the table moves on the forward stroke and on the back stroke. Judging by the shape of the pin, it looks like the pin should disengage and ride over the teeth.
