5) The first step was to break off the PCB parts used to form the input and output transformers and file the edges. It only took a minute to make all the edges super smooth and nice to work with.

Next I chose a heatsink: an old CPU heatsink salvaged from a trashed computer. Then I drilled and tapped M3 holes. First time for me tapping holes in metal, and drilling in copper. The drilling was harder than I expected. The holes ended up a millimeter or so from where I planned, but it doesn't matter.
