Boring!

The previous week was mostly spent on creating the tool in the photograph below, by filing down a normal drill bit to somewhat more square proportions, and silver-soldering the piece of copper on its otherwise sharp tip. This copper piece has exactly the same diameter as the pilot hole that was drilled in the wood earlier, and ensures that the drill follows this guide exactly instead of scraping its own way. I also had to file down the width of the drill bit, since I required a somewhat irregular size for the socket. The piece of black tape marks up to where I want the drill to enter the wood.

Next, it was time to drill the actual bore. First the socket, using the drill I just made, then gradual steps from 14mm down to 11mm for the right hand / foot piece. (Luckily most of these drills were already filed down by people before me.) Finally I was able to use an already existing reamer, too. For the left hand (middle) piece, I'll have to make my own reamer, which will be mostly wood with a metal scraper, but that is yet to come.

To ensure a smooth flow of the reamer, some linseed oil was applied, which leaves quite a color mark on the wood (its first oil ever!), and actually makes it smell like a fresh salad.
