I assume you are talking about machining on the OD of the liner? Maybe a lip or a groove? You don't machine the ID on a lathe, you bore or grind the ID. As for a Harbor Freight lathe, you will be very unhappy to say the least. You will also need additional tooling to support the liner while you are working on it and I don't think they sell that kind of tooling.
You are right about buying liner blanks. There is probably a size liner for anything but they are mostly made for a dry install in an overbored cylinder. No O rings or seals
. Liners with sealing surfaces etc., are made for a particular engine
, they are not just a generic liner that somebody machines on a little cheap lathe. For example a Perkins
107 is a wet liner and needs an O ring. I doubt you could make one of those but then they can make a gun on the street corner in the middle east with hand tools so who knows.
