I'm in the market for a lathe. Of course, now that i have a little money to throw at it, boeing surplus and James G Murphy have got nothing at all. I could buy a new unit in the 13x36 or 14x40 range, but i'd rather find something used that would hopefully be a bit larger. The primary use would be turning up to 4" diameter aluminum tube (and possibly 6"), reducing the OD, cutting internal and external snap ring grooves and internal threads. In a perfect world it would have a large spindle bore so i could pass the tube through the headstock instead of using a steady rest when possible.
Anyways, if anyone knows of a lathe that would fit the bill, somewhere in the pacific northwest (within a couple hundred miles of seattle), please drop me line.
