Sherline 5000 Mill Assembly Instructions

-26-
“single pointing” a thread. When the spindle turns, the
saddle moves. If they were geared one-to-one, the cutting
tool would cut a pitch that would be the same as the
leadscrew. On Sherline’s inch machines, this would be 20
threads per inch. If the leadscrew turns 180° while the
spindle turns 360° (by using a 20-tooth to a 40-tooth gear
reduction) we would cut 40 TPI. Note that threads can be
applied to any diameter stock.
Sherline’s thread-cutting attachment provides all the
necessary gears and support arms to cut any thread from
80 TPI down to 5 TPI. Both left-hand or right-hand threads
can be cut. With the use of a 127-tooth change gear, metric
threads from .25 to 2.0 pitch can be cut on an inch machine
and inch threads can be cut on a metric machine. A large
handwheel replaces the motor and speed control to drive
the spindle, so that you have total control over the thread-
cutting process. Though this might sound like a step
backwards, it actually is a very practical system for cutting
small threads, allowing you to cut right up to a shoulder if
need be. A carbide 60° thread-cutting tool is included, and
an inside threading tool (P/N 1200) is also available as an
option. Complete instructions include a chart of the gear
combinations to achieve the threads mentioned above.
With this attachment and your lathe, you will never be
stuck without a way to come up with the right thread.
Even if a tap or die is available, you can set up and cut a
thread faster than you could get to the store and back to
buy it and save yourself some money as well!
STEADY REST, P/N 1074
The steady rest supports longer work with three
adjustable brass pads. It keeps long parts from
deflecting away
from the tool or
wobbling while turning and
steadies the end of long
parts for center drilling.
Along with a live center, this
is one of the first
accessories most lathe
owners add to their tool box.
ADDITIONAL LATHE ACCESSORIES
1090 Follower rest—Moves with lathe saddle.
Two brass pads provide support right behind the
cutting tool to keep long, thin stock from
deflecting during a cut.
1160 (1178), 2100, -01, -02, 1162 (1179) WW Collet sets—
Holding work in individually sized collets
is a more accurate method than holding
in a chuck. A number of sets of standard
collets, collet pot chucks and deluxe collet sets are available.
1182 Bullnose live center—For supporting the
end of tubing or parts with a large end hole up
to 1-5/8". Two preloaded ball bearings, #0
Morse tapered shaft.
1185 (1184) Vertical milling table—Mounts to the
lathe table to provide a vertical Z-axis movement
of 2.25" (57 mm). Although the vertical milling
column (P/N 3050/3053) is the preferred method,
this is a traditional method of doing small milling
jobs on the lathe. It is also useful for special setups on the
vertical mill.
1191 Live center—Replaces tailstock dead center
for holding work. Ball bearing reduces friction
while turning between centers.
1201 Adjustable live center—Ball bearing live
center with adjustable backing plate allows
precise alignment of headstock and tailstock.
Adjustable tailstock accessories like P/N 1201,
1202 and 1203 are for the craftsman seeking the ultimate
in precision.
1202 Adjustable tailstock chuck holder—Allows
perfect centering adjustment for tailstock chuck.
1203 Adjustable tailstock custom tool holder—
Adaptable to hold any tool you wish on perfect
center in the tailstock.
1206 Adjustable tailstock 1" die holder—Holds
1" dies for threading shafts. Includes a 13/16"
bushing for holding smaller size dies.
1270 Compound slide—Mounts to the “back”
side of the lathe table. Allows cutting of angles
that can’t be achieved by “swinging the
headstock” or turning between centers. Laser
engraved base has angle scale for reference.
1290 Steady rest riser block—Raises steady rest
to proper height for use with headstock and
tailstock riser blocks.
1291 Headstock riser block—Raises headstock
1.25" (31.7mm) for more clearance to turn
larger stock (up to 6" in diameter). Also
includes riser rocker tool post.
