Step two, buy mill
This was a fun one. I saw a listing on craigslist for a small horizontal milling machine. It was about two hours south of Seattle in a little town called Castle Rock. The photos looked pretty cool, and it had a shop made vertical head and a bunch of tooling. I had never used a horizontal mill, but after some very brief research I decided I wanted it. The price seemed reasonable, but what did I know.
I drove down to get it on a nice sunny day and met a great guy with an amazing shop. He is a tool collector who specializes in old metal levels, but he clearly has room in his heart (and garage) for many other things. Particularly if those things are made out of cast iron.
