South Bend used the standard gearbox off of a 9"/10K lathe for the
optional table drive on their milling machines.  It has
30 feeds from 1/4" thru 15"/minute. The gearbox chart was
relabled accordingly.  My mill did not have a drive shaft
when it was acquired, but the rest was there.  The requirement
is for a 3 stage telescopic.  This was made with the idea
of getting something made "quickly" with odds & ends in the
shop.  It does not exactly reproduce the stock shaft, which uses
moslty hex sections.  I wobble broached the larger brass bore.
The missing universal joint was made from 954 aluminum bonze,
3/16" dowel pins, and a steel spider.
