From Mike Darlow Woodturning methods.
IEH Saueracker was an outstanding ornamental turner died 1942 aged 87.
(German)
It requires the workpiece to be turned on a large number of different, but
parrallel axes. "

That went on for way too long. and I dont understand it well enough to
explain quickly, I have a pic if your interested (just remove the asterisk),
but you would probably see it and say ,"ah those"

I found it looking up eccentric turning 6 months ago and cant find it again.
