Inside a ratchet: How they work

As a new guy on the site, THANKS for creating a wonderful reference piece. Is there a way on this site to "Sticky" or "Leave at the front of the forum page" such an informative post?

Glad we could help you out, bz. And - if you have any ratchets not yet pictured - take 'em apart and post some photos. I'd love to see what you've got. B-man

The Walden Worcester Ratchet is a little Plumb/Proto like, and a little New Brittan like.

The first thing that is odd is, it has screws in both sides.

You want to take the 2 furthest from the handle out first.

The poor ratchet below also shows the weakness of this design, all the force on the pawl is focused at the screw, when forced, the thin end of the pawl breaks and the pawl jumps out of place and i t's all over...

There's a guy over at the gazette who posted pics of a new Proto with the double see-saw pawls like the Craftsman RHFT and the Triangle-era Bonney's. He says I can use his pictures - as soon as I figure out how to import someone else's pics off of photobucket, I'll post them here.
I believe it is a 5452A in 3/8"

Right click the picture on the Gazette, read the properties, copy the url, and paste here, using the picture icon above the post text box.

Let's try that:

And the gear assembly:

This gear assembly is remarkably similar to the Bonney gear, though it has QR (whereas the Bonney does not). But the similarity of design and manufacture is uncanny.
