Sherline 1206 Adjustable 1 in Die Holder
The 1″ die holder utilizes a split plate design to achieve
centering accuracy. A 1″ button die is held in the face plate, and
shafts held in a chuck or collet in the lathe headstock spindle can
be threaded. The tailstock is not tightened to the bed, so the die
is free to feed itself onto the part as the part is rotated by hand
with the spindle, preferably with the large handwheel from the
thread-cutting attachment or the P/N 2049 spindle handwheel.
Included is a 13/16″ bushing that allows smaller dies of that size
to be held as well.
Much like the adjustable live center, holding a die in perfect
alignment in the tailstock without some method of adjusting it can
be difficult or impossible. To achieve perfect centering, the die
is mounted in a front plate. The rear plate has the #0 Morse taper
that goes in the tailstock spindle. Slightly oversize holes in the
rear plate allow the two plates to be adjusted in relationship to
each other so that the die can be brought into perfect alignment
with the headstock. This is an economical way to have the accuracy
of an adjustable tailstock for those who need it while keeping
costs down for those who don’t.
