SOLD Vintage Craftsman
/ Atlas Lathe SOLD
Craftsman 12" x 36" lathe. This is my
father hobby lathe in excelent condition. The bedways have no
large nicks (see enlarged pictures) as best I can recall, no visible
wear. I'll say 99%, just needs tuning, tightening, and comes with
a very rigid stand that is available if you want it.
Original toolpost and craftsman tool holders. Has
a 120 V motor . There is no noticable noise paint is like brand
new under the cutting oil, will clean up very nice, just do not
have the time to do it.... This is a fairly modern version of
the Atlas lathe having threading gear box. It is the Craftsman
model 101 289 10 ser#107436
This is a detailed description I found on the internet
of this series of lathes made from 1959 to the 1980's (http://www.lathes.co.uk/atlas/page4.html):
The final form of the Craftsman
12-inch was identical to the new-for-1959 12-inch Atlas (for further
details of how these Craftsman lathes changed over time, look
at the Atlas section of the Archive). From this point on the Atlas
and Craftsman versions of the lathe were identical with the same
6-inch centre height and both fitted with a conventional tumble-reverse
assembly to drive the leadscrew as always used on the Craftsman
version (the Atlas had employed a bed-mounted bevel box to achieve
the same effect). Besides numerous detailed changes to the lathe
the greatest single advance was the option of a neat self-contained
underdrive cabinet stand that made the machine much more acceptable
to training and education establishments as well as saving the
home user valuable workshop space.
Depending upon their individual specification - various combinations
of bed length, motor type, screwcutting by changewheels or screwcutting
gearbox, etc. - the lathes are found with the following (and probably
additional) Model Numbers: 101.28950, 101.28910 or a similar 101.289**
number including: 101.2758, 101.2759, 101.2895N, 101.2893N, 101.2894N,
101.2897N, 101.28990, 101.28991N and 101.28993N2.
In the 1970s the lathe carried a "Craftsman Commercial"
badge, though by the early 1980s this had been changed to "Sears
Craftsman".
Atlas 12" x 36" long-bed
Introduced during 1959 this lathe, variously designated as the
"late-model 12-inch Atlas" and the "Series 3000"
was major redesign of the original and very popular 10-inch Atlas
lathe that had enjoyed a production run of over 23 years. Although
the flat-topped "English-style" bed still flew in the
face of American preference for V ways, the rest of the machine
was heavily revised and few parts were interchangeable with the
earlier model. It was available in two versions, for either bench
or stand mounting, with the former having a bronze-bearing countershaft
(of rather agricultural construction) and integral hinged (cast-iron)
motor mount that bolted to the bench behind the lathe (with a
bracing arrangement to the back of the headstock) together with
a lever-operated mechanism that slackened both headstock and motor
belts simultaneously. The stand lathe sat on a neatly-constructed
190 lb cabinet (made from 3/16" thick steel with a chip tray
as standard) that held a simple but robust countershaft with its
pulleys overhung on 3/4"-diameter shafts from each side of
bearings contained within central plumber blocks. Both models
had an almost ideally-useful range of 16 spindle speeds that ran,
in backgear, from 28 through 45, 70, 83, 112, 134, 211 to 345
rpm and, in direct drive, from 164 through 266, 418, 500, 685,
805, 1270 to 2072 rpm. Neat cast-aluminium covers guarded both
the headstock and motor belt runs and the changewheels.
Strangely, although the bench model had a single V belt drive
to the headstock the underdrive model used two - a design that
can often lead to trouble when worn or unmatched belts are used.
If your 12-inch underdrive suffers from a noisy headstock, vibration
or a poor finish on turned work, look first at the final drive
to the headstock spindle and check (by putting a chalk line across
them and running the lathe) that the two belts are exactly the
same length.
Whilst almost every 3000 Series lathes appears to have been fitted
with a screwcutting gearbox some were made with a standard changewheel
set up; the sales catalogues were a little vague on this point
with publications for the American market sometimes listing the
gearbox as a standard fitting on both stand and bench models but
sometimes as an extra on the bench model only; export editions
managed to show it both as standard unit and, simultaneously,
amongst the extra-cost accessories for both versions. The gears
within the box were of unhardened steel with all the bushes, whether
for gears or rotating shafts, of the simple bronze Oilite kind
lubricated through handy, dirt-excluding flip-top oilers. The
"English" box was able to generate feeds from 0.0042"
to 0.520" per revolution of the spindle and 54 threads from
4 to 240 tpi whilst that fitted to the rare all-metric machines
gave feeds from 0.089" to 6.0 mm and 29 threads from 0.1
to 6.0 mm pitches. The 3/4"-diameter 8 tpi leadscrew was
slotted and carried a sliding key that drove, via a worn-and-wheel
within the apron, the power cross feed mechanism; end thrust in
both directions was absorbed against radial need-roller bearings
and, fitted at the headstock end of the shaft, was an over-load
protection device designed to slip and prevent damage to the gearbox,
its (steel) changewheel gears and the apron mechanism.
The headstock spindle, with a 1.5" 8 t.p.i. nose, 25/32"
bore and 1/2" collet capacity, ran in Timken taper roller
races; instead of being mounted to the rear of the spindle in
traditional fashion the backgear assembly was built into the lower
part of the headstock, rather like a Clausing or Raglan lathe,
and engaged by a convenient lever protruding through the front
face of the headstock below and just to the left of the spindle
nose.
Whilst the apron and 11.25"-long saddle with its 33.75 square
inches of bearing surface were strongly constructed - and the
latter fitted to the bed by adjustable laminated shims - the compound
slide rest could only be described as adequate for its purpose;
the cross slide was of the type that, not being full length, caused
wear across the central part of its movement and, to enable the
cutting tool to be set at the lathe's taller centre line, the
top slide base was simply "built up in the sand" to
increase its depth. On the positive side the zeroing micrometer
dials were clearly engraved and the mechanism to lock their rotation
by positive finger screws.
In 1967 a minor change was made to the apron-mounted mechanism
that engaged the (standard-fit) power cross feed with the provision
of a simple, ball-ended toggle arm that slid the selector button
in and out.
The tailstock was provided with an adjustable gib fitting to the
bed and held a 1.125"-diameter ground-steel ram with an No.
2 Morse taper socket and engraved ruler marks from 0 to 3"
in 1/16" steps. The clamping handle was permanently attached
at the rear of the casting and, because room within the back of
the casting was limited, was of the type that could be swung up
and round to give a ratcheting action.
Unlike earlier Atlas lathes, which were without any form of dating
(apart from the headstock roller bearings), some if not all 12-inch
models had casting dates on the inside of their beds: a mark such
as 9-2-59 would indicate a pouring date of September 2nd 1959
- providing the foundry workers had bothered to change the mould
numbers, of course.
I will coordinate shipping from Wilson, NC 27822
zip or Raleigh, NC 27609 zip estimate lathe weight less the stand
is about 350 to 400 lbs. High bidder responsible for all insurance,
shipping & crating charges.
This item to be for weekend pickup in Wilson or for Raleigh, NC.
Please bear in mind that my father was a hobby machinist and that
my assessment of this lathe is not at the deepest technical level.
Would make a great Christmas present for yourself
or someone that loves metalwork ....
