Wired interviews sculptor Jeremy Mayer:

It took a little over a year (1,400 hours) to make Delilah. I have a couple of rules about my process: I have to use only connections and parts indigenous to the typewriter — no soldering, welding, gluing or wire-wrapping is allowed. Second, I try to bend, drill or cut the typewriter components as little as possible. I do cheat a little, but only serious typewriter buffs would be able to tell which parts I’ve modified from their original form. I don’t tap new threads at all.
