Clickspring has an amazing series where he builds a replica of this using techniques from the era. He makes the drill, vise, files, etc from raw materials, its really interesting.
In the process he actually discovered a key detail about what it's purpose was and helped write a paper about it.
Anyone know of an actual source for this fact? Wikipedia removed it, and the only other references are sketchy websites that seem to have picked it up from wikipedia and reddit threads with no sourcing. Seems like it should be something easily verifiable.
