Yesterday morning I had a rush job from a local print shop that needed a cylinder turned down. It should have been ground but there was .080" to remove and no cylindrical grinder in sight. Turned down a Rovi internal collet to drive the 13" long roll and held the other end with a live center. When I was done I had held the 2.008 +.0002/.0005 but just barely. One end was .0007-.0008 bigger then the other end but then again this is a 30+ year old lathe that has been in production shops its entire life. My measurement may have been slightly faulty as all I had was an Etalon micrometer verified with gage blocks. I am not here to boast about my machining abilities but I don't know of a better lathe for a beginner then a Hardinge. It puts all the errors back in the operator's hands and gives truly precision work. Leigh at MarMachine
