I am rebuilding and tweaking a guy's old Craftsman metal lathe. I have a
machinist's background but I'm not familiar with this little lathe.
-
Model Number is 101.21200
Serial Number is 001773
-
Name tag states Sears Roebuck USA and Simpsons-Sears Limited-Canada
-
Swing is 6 inches. Bed is 18" center to center approxamately. 3 jaw and
4 jaw chucks are both 4 inches in diameter. Leadscrew is 1/2" diameter x
16 pitch . Leadscrew gear is 64 tooth; stud gear is 48. I have a set of
9 other gears, but no thread gear chart so I guess I'll be figuring this
out long-hand. * Largest gear in set is marked: M6-101-56 ; 56 being
the tooth count. No quick change threading gear box like a South Bend
10K. Lantern post will take 3/8" wide shank tool holders. * Of course
no operators' manual!
-
Anybody know where I could obtain a threading / feed gear chart?
Operators manual would be nice, too!
-
There is a big gear by itself in back of the spindle, within the
gearbox. This gear can be moved in and out on an indent lever also
behind the spindle, moving it fore or aft. Is this to be used as a back
gear arrangement to allow low gears? When I engage it, it effectively
locks the spindle, but I can't figure out how to get the spindle to spin
free. A South Bend lathe has a pin to pull back to freeup the back
gears. What am I missing here? Or does this gear have another function?
-
I found a couple other Yahoo! groups specific to Craftsman / Atlas.
Anybody know of other sources for info?

I second Jeff's recommendation on the Atlas/Craftsman group. There is
also a group just for the 618 lathes.

Manuals and parts are available from Clausing.

When you engage the back gear, you have to disconnect the cone pulley
from the bull gear. The bull gear is the large gear on the spindle.
There is a pin going through it, from the right, into the pulley. The
pin has a large head on it - lever it out with a screwdriver or
something similar. The pin is locked by a ball and spring, held in by
a setscrew from the rim of the bull gear. If the pin is locked, you
may have to back off on the setscrew.

John Martin

In addition to the Yahoo Atlas_Craftsman group, join the Atlas618Lathe
group. You'll get a lot of information there.

I *think* that is the Craftsman version of the 6" Atlas.

Anybody know where I could obtain a threading / feed gear chart?

If it is anything like mine, you will find a threading chart
riveted to the inside of the gear cover. That way, you will be sure
that it is the right one for the machine.

Operators manual would be nice, too!

Try contacting the Clausing Service Center:

1 (574) 533-0371

and have the serial number and model number available, and you will be
able to buy a manual for the lathe (a photocopy of their collection of
manuals, tailored to your serial number). They might even be able to
tell you when it was made. The could with my Clausing 5418, which was
made in 1957.

There is a big gear by itself in back of the spindle, within the
gearbox. This gear can be moved in and out on an indent lever also
behind the spindle, moving it fore or aft. Is this to be used as a back
gear arrangement to allow low gears? When I engage it, it effectively
locks the spindle, but I can't figure out how to get the spindle to spin
free. A South Bend lathe has a pin to pull back to freeup the back
gears. What am I missing here? Or does this gear have another function?

Nope -- it is the back gear. The bull gear should have a pin
coupling it to the cone pulley. You may have to rotate the spindle as
much as half a turn to bring the head of the coupling pin into reach.
Once you pull that, you can operate the back gear lever to engage that
and have nice slow speeds with lots of torque -- at least lots for a
machine of this size. :-)

[ ... ]

I have the original manual that has the speed chart. Send me an email
address with your request(s).

That will help him -- but as I said -- I *think* that the
threading chart is inside the gear cover. Mine is, at least.

Good Luck,
DoN.

Your description I think applies to the older Atlas and Craftsman
lathes, similar to the South Bend 10K lathe (pre-1973 Atlas) where the
pulleys are internal in the middle of the headstock, accessable by a
liftup, hinged cover .

Nope, no riveted gear chart.

Mine doesn't have one either. I think I'll have to score a cover off
ebay, then re-sell the cover after removing the chart.

Can someone please post a direct link to the Mk2 .PDF Manual here? I
was unable to access it from the link provided above.

Thanks

I'm pretty sure it's on the Atlas 618 Yahoo group files section.
I'd check but I've divorced myself from that bunch.
