The manual addresses speed with the sleeve bearings. It states that the
clamping pressure should be reduced slightly for high speed and
tightened back for slow speed. If it states what speed is high vs low I
didn't catch it.

Interesting. I knew about the oil recommendation changing, I never knew they were putting timkens in them as early as 1937. I wonder now if the timkens were sold as a high speed option, or if they were having trouble figuring out which way to go.

?

I've looked through a bunch of pdf's and a couple of original printed
manuals. My original 1937 Atlas manual never mentions 618 or any other
model number, as best I could tell, but it discusses both bearing styles
and shows pictures of both styles.

I noticed one little tid bit of information. In the 1937 manual 10
weight oil is used. In the later manuals, 50s/60s and later, 20 weight
is used.

Hi Bill,

Hopefully here's some pics you might find interesting.

.177 cal, precharged pneumatic. Get around 55 shots on a 3000 psi fill.

The stock was the most difficult part for me!

I'm thinking cut rifling, but button has some advantages, and disadvantages, that differ from those of cut rifling cutters. So I may have to play with both, and see which works better for the things I want to do. I'm thinking something for pistol barrels first, as much for practice and play as anything else. And I'd be delighted to see any photos you want to share!

After a 20+ year hiatus, I've recently gotten back into reloading, and casting bullets, and I've wanted to make a, call it a .45acp Magnum for lack of a better description, 1911-style pistol in the .44mag power range. Or an 1896 Mauser in the .30 cal version. Or both. ;)

I have a hammer forged BSA barrel on my hand rolled PCP rifle.

Hi guys,

I'm just sitting around enjoying the balmy 3 degree weather, supposed
to have a high of -11 Wednesday!

Anyway, Robert is correct regarding the dust covers among a lot of
other stuff!!


My left oil cup actually empties faster than the right as well after
looking due to this discussion. Why?

Hello everyone!
I picked up an old Atlas and have finally got around to messing with it.
I got the bed and all the ways on the compound, cross-slide, and suck nice with some kroil and a dish scrubby pad
I got most everything freed up and turning nice (spindle turned when I found it and seems nice and tight)
With a little luck, and some friendly advice, I may get this thing making chips before too long!

I do have some questions about these old six inch lathes.

I've read conflicting information on spindle bearing types, I understand the first craftsmans had a small spindle, besides that, is it correct that the 8TPI spindles are sleeve and the 10TPI are timken? That's mostly what I've read, mine has 10TPI and two little oil cups with spring loaded covers over the bearings.

Also I'm having trouble removing the gear from the leadscrew. It had a bolt and two washers in the end of it, removing it exposes the shaft and what looks like two woodruff keys? does it just need a little more time in the oil? I have removed the leadscrew. The left leadscrew bearing, though there's nothing stopping it, gets extremely tight if I move it as much as 1/16-1/8 of an inch to the right, I don't want to force it that way but I want it out or at least off the journal to clean.

Thanks to anyone who reads this, more so to anyone who is able to help.

I seriously doubt that how well the dust covers seal around the spindle has anything to do with oil flow rate.? In the first place, the dust covers don’t come anywhere close to actually sealing to the spindle.? However, they could be blocking the hole in the top of the headstock.? I have suspected for years that that is the reason for the large imbalance on my 3996.?

Are the felts in your oil cups factory or not?? If not, then none of us have any basis for comparison.? I don’t mean to imply that there is automatically something wrong in using locally procured felt.? Just that there would be no basis for comparison.

I'm guessing the oil loss differential from the front to back bearings has to do with the metal dust caps sealing better on one end.

I'm curious if other's oil cups are empty on the spindle each time they use it?
Thanks,
Jody

The bearings as Robert points out do not have shims nor is there a "cap" there is however more what could be described as a clamp (see photo, chuck side is the same). This clamp (please correct me if you know the proper name) can be tightened but with great caution as the clamps can brake/crack. Tightening will remove some of the slop in the spindle, I would not use more than a firm hand on a screw driver to be safe. Also see a photo of the replacement bearings with no "holes".

Robert, is there any known specifications for tightening the bearing clamps, inch pounds, number of turns... or ?

Hi Bill,

Good news about your wife! I Hope things go well.

I do know a guy that made a stock out of a 2x6, not pretty.

I'm not a woodworker either but I have been known to put some wood on a metalworking machine.

I have more pics of various projects if you or anyone else is interested, off topic but fun.
