I've been trying to re-locate the pic PBR posted showing what looked like the same or similar mill as I have in his ship he used for doing seats etc. As I recall it was in a thread you started back in 2020 or thereabouts.
I’m pretty sure he bought an older guide and seat machine, like one of the smaller Winonas.
Prior to that I believe he was using Neway cutters for freshening seats, and things like machining seats for larger valves were outsourced locally.
