All the parts of the two-toothed ratchet model are coming together nicely. I've extended the support that guides the pull tab so that the tab is pointing the right direction to move the pawl housing. I forgot to extend the sides hence the pieces sticking out on the bottom right of the picture above – easy to correct.
I've put together this quick animation showing how the model works. I'll put it together as a downloadable model for members, hopefully tomorrow, then I'll work the mechanism into a finished character based model. I have a couple of ideas that could be fun 🙂
I'll tell you what though, I forgot about end stops. I need something that limits the range of motion of the pull tab. I'll have to think about that over night.
