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
