Plug Spinner, made of cedar wood with a cork handle and mousetrap spring. Inspired by a design on here I saw, OP used a dowel and I wish I could remember his name to give credit but alas. Anyways this is my version, it work okay but not fantastic by any means,

Sargent and Greenleaf 6730 cutaway, I replaced the back plate and some of the side with plexiglass, as well as painting the inside black to make it easier to see the parts.





This Master lock came with the Foley Belsaw course, pretty cool cutaway this shows you where to drill to make a master lock cutaway.


And finally I've got a Railroad "lock", a shackle held in place by a six sided bolt with grooves....
Not too secure when you can open it with a fork!



Anyways, that's all I've got for now.
Whats new around here, anyone who remember's me around?
