table is 2" high and 4" (100mm) in diameter. The main components have
been machined from solid bar stock steel, and the complete unit weighs seven
pounds. The table has been engraved with a laser, giving sharp and precise lines
every 5°, numbered every 15°. These lines are calibrated with the 72-tooth
worm gear that is driven by the handwheel. The handwheel is divided into 50
parts, making each line on the handwheel 1/10°. This allows a circle to be
divided into 3600 increments without interpolation. Seventy-two revolutions of
the handwheel rotate the table one revolution.
The table T-slots
are identical to those used on the Sherline mill and lathe, making the vast line
of Sherline tooling available for use with this product. Two hold-down clamps
and T-nuts are provided with the table. Also included is an adapter that allows
Sherline’s 3- and 4-jaw chucks to be mounted directly to the rotary table. An
optional right angle attachment is available (P/N 3701)
to mount the table in the vertical position to further increase its versatility.
With the table mounted vertically, an optional adjustable right angle tailstock
(P/N 3702) can be mounted to the mill table. It is used
to support and stabilize the other end of long work held in a chuck or otherwise
attached to the rotary table.

rotary table has a unique table locking mechanism that is positive and does not
move the table as it is locked. (See the
white notched cylinder and gray set
screw in the ghost view above.) To maintain accuracy and frictionless movements,
ball bearings (dark blue in ghost view

keep out chips and dirt. An oiler is easily accessible to facilitate lubrication
of the table. The appearance is instrument quality with a black oxide base,
precision ground finishes and laser engraved markings.

Any machinist who
wants to take his capabilities to the ultimate levels should consider purchasing
and learning to use a rotary table. The Sherline rotary table is an extremely
precise and well-built piece of equipment that is sized to fit with our product
line. It can also be useful on larger equipment when its compact size is called
