What is the special purpose of this 18″ ruler. There are 4 windows. A: In the olden days, before personal computers, I worked as a type setter in a print shop. Type would be produced on film, run through a wax machine to wax the back of it and then cut apart and placed in position. To save on film, everything was smooshed together, you had to cut it apart and move it into place…every line, number and punctuation. I had a tool like this, but it was much longer. Sometimes it was more useful than the T-square.

Two tone 3D printed object on a necklace from a youth military program in the US A: Most kids who go through Starbase get one of these. The purpose is to demonstrate CAD and 3d printing, not to provide any practical result. Students are instructed to follow along with instructions to model a “space capsule” (the program is designed for elementary, so the simplicity is somewhat warranted), so every student produces an identical model. Then the instructors hand out a 3d printed version to every student.

What is this set of identical flat wooden shapes found in an old box of Christmas decorations? I can sort of stack a few but they don’t really interlock. There are 10 of them. A: We had these growing up. They are used to organize your ribbons, cords, strings etc for decorations or wrapping. You would start on one end and wrap your ribbon (etc) at a diagonal and then again to the other diagonal etc etc. it made sure none of your ribbons got tangled. We used these for ribbons, strings etc. you can also get them in plastic and larger sizes for a string of lights.

What are these two cylinders on an elevator/lift control panel labeled ABCD? A: Those are for installing locks (normal keys with keyways) to enter areas e.g. floor 13. Keyways are at least 5cm (2″) deep so they needed a way to orient them sideways as the button assemblies are not deep enough. For smaller buildings where those are not needed those are just design elements.

What is this tool with a spring inside (visible when the top is unscrewed) and multiple bits (maybe) in the base? The base rotates and has a small hole in it to release each bit when in position. What’s the purpose of this tool? A: It’s a yankee drill. Put the bit against wood, and when you push the handle, it drills!
