Sure is. It's a good size, too. I just added it to my collection.
It's interesting checking out the different types of mechanism and construction methods.

You got me thinking, Col.
While waiting for the workshop to warm up this morning, I've been playing with designing a much smaller padlock, and it led me to thinking about a more efficient wooden spring shape, to fit into a smaller space.
What would be the best shape? 'U' shaped?

Besides this, the main limiting factor is the thickness of the shackle. I'd like to make it 8mm thick, but it might be a bit weak. It needs to be shaped from a bent piece of timber, a bent branch, before it could be made too thin.
Anyone tried bending 5mm or 6mm dowel?

Edit: I'd show my crude drawing, but my scanner died a few days ago. Gotta get a new one.

This is the basic design I'm thinking of. It has one less moving part than the one I'm currently making, but still has a long, flat spring. It should be more reliable and easier to make, though.: -
Edit: I might need to alter the position of the lever pivot or the shape of the lever where it contacts the key to get the required travel. I'll cut out a cardboard pattern and test it. I got 50 sheets of cardboard for this purpose yesterday.

Hermit, take a break. Read some history about padlocks & keys. Imagine! Doors locked. Nobody can sneak in and kill the king. Prisoners locked in their cells. Nobody can steal your stuff.
Imagine the finesse needed with primitive iron mongery to make such devices! We try to approximate their effort.
BTW, how does one 'mong' iron anyway?

It's not really an exercise on lock making. It's a toy.

Hi Steve Thanks for keeping me in the loop I am not sure what would be the best I think you’re on the right track with the overall idea of trying different methods and practices and getting the best outcome with the padlock.
I am following this thread and looking forward to you completing your padlock. As soon as I finish the road grader project I will get into the wooden locks by that time you would have gathered a lot more experience and possibly developed your own techniques and maybe able to help me on my journey with them. If you want to make the lock smaller this link may help.

Not bad Col. Looks good. Similar to the one I'm building in a way.: -
Attachment 221405

After I finish this one, I'm looking forward to building my own design rather than using off-the shelf plans. More fun.

It's probably time I got the thread started on this build. It's getting there.
I've been making notes and taking pics all the way, Col.
(That's just my temporary Camphor Laurel spring in it for now. A bit short, but OK for testing.)

I got the build thread started here https://www.woodworkforums.com/f174/my-first-attempt-working-wooden-padlock-158039/
(The book design.)

Woodwould, your parcel just arrived, with the Ash and Yew pieces.
Enough to make heaps of springs. Thank you very much for that.
I can get busy tomorrow making a couple more springs.

W.I.P. looks great Steve keep the pictures coming

Brian (Wizened of Oz), your parcel with the Hickory and Tallowood also arrived this afternoon.
Thank you for that.
Even more spring-making.

Thanks, Col. Will do.

I thought of another good candidate for springs today. 2.5mm Bamboo skewers.
Had one in my hand today, to spread glue, and noticed that it had a nice amount of flex.

Wouldn't suit my current lock, but worth keeping in mind for the future. Slightly weaker than the 1.4mm x 17mm wide strip of Camphor Laurel.

With a hammer.
