Oh man, I didn't even think about that.? That's a good idea if
this carriage bolt doesn't work.? I'll keep it simple for now with
a carriage bolt.? I might have a t nut laying around for the x-y

Re: Missing Feed Gear Bolt
Jody, ? Besides a third special bolt (9-69A), the Atlas 10F and early 12” all came with a third 9-73A Sleeve, 9-70A Bushing and 9-93A Washer.? When you call Clausing to order those, you may as well order the bolt as well.? ? Atlas practice was that if a commercially available part would work they used it.? So if a carriage bolt would have worked, they would not have made the 9-73A instead.? The problem with using a carriage bolt is that the square piercing part that sticks out from the head is slightly tapered,? and will hit the sides of the slots in the banjo only at the inner edge.? Plus the tolerance on the diameter is pretty sloppy, especially if it is Chinese made. ? ?

Early 60's sounds like a reasonable date. I believe all three lathes
came from the same individual - a deceased relative. I think he started
out with the Sears, then passed it on to his brother-in-law when he got
the Atlas. The Sears may never have been used as that guy ran a
woodworking shop. He died and it went to his son - my wife's cousin. I
got it from him in a trade as he wouldn't take an old dilapidated 5x8
trailer for free. The relative then bought the Levin from NASA and set
the Atlas aside. Some years later the Atlas went to my wife (before we
met) and the Levin was destined for, but never picked up by, my
sister-in-law. My wife saw my interest in the Levin so bought for me a
birthday gift. So, now I've got three lathes, all disassembled for
moving, though I did use the Atlas for an hour or so before it was
moved. The Sears spindle moves, but I have no motor and no space to set
it up separately. The Levin spindle does move, though all of the parts
are covered in rust. I'll make room for it and get it working some day.

Re: Missing Feed Gear Bolt
The original stud is very similar to a carriage bolt, with exception that gear bolt has a thicker head and is flat, where a carriage bolt is domed. I'll stop by HD and give it a whirl. Thanks, Jody

Attached are a 3 documents that confirm Robert's point regarding Atlas lathes and other machine equipment's limited accessibility. Individuals or companies had to apply through the "War Production Board's Controlled Materials Plan (C.M.P)" and justify their need. Referencing these documents,This was at least through late 1944.

Re: Missing Feed Gear Bolt
Animal,? It is similar to a carriage bolt.? The square portion at the head fits into the banjo slot and keeps the bolt from rotating.? The flange of the bold keeps it from sliding thru the slot of the banjo.?
In your plan what keeps the bolt from sliding out of the banjo. -Jody

The gear bolts have a thicker head on them versus a carriage bolt,

I don't see why not since there isn't tension on the fastener.
Just want to see if you guys thought that was OK.? I don't even
know if you can find a bolt like the one on the lathe.

OK, I’ll grant you that but my point was that the Atlas lathes were primarily advertised to or for small shops, not hobbyists.? And any that were involved in the War effort certainly were not considered as hobbyists. ? ?

Robert, based on the number of articles in Popular Mechanics from the 30's and early 40's there would have been some number of hobbyists using lathes in that period. During WWII there was a government effort to enlist these people into taking on war effort subcontracts making parts.??

Although they cost less than the Clausing and South Bend lathes, they still cost more than a weeks pay for most US residents.? The hobby market didn’t take off until after WW-II when people began to have a little extra cash each week.? The only private individuals who could afford one during the Depression were rich ones primarily in the North East.? And during WW-II, even they couldn’t buy one unless they bribed some official. ?

Re: Missing Feed Gear Bolt
Hi Jody ,
There are a couple of factors to take into account when cutting stainless . .?
> It work hardens easily
> One needs to CUT , not rub . . .
> The cutting speed must be such that it doesn’t get hot . . .
> It needs to be liberally lubricated . . .
Not nice stuff to practice with :>( ! ? Take care , ? Carvel ?

Re: Concern with my Spindle
Robert,
I think it is all coming out of the front dust cover.? Which makes sense because the riding bearing surface is angled towards the chuck so you would expect it to follow the bearing and bearing surface.
I'm wondering if I had a burr on the dust cover when I reinstalled it and it has a little gap for the oil to flow through.
it's weird that without the felt, the oil runs out immediately but with the felt it runs out 3x slower than the rear oil cup with felt.?

Re: Concern with my Spindle
Jon,
The oil is that really lightweight thin oil that several recommended on here for the Timkem bearings. ? As far as "immediately"....I mean immediately.? I can't fill the cup up because it runs out so fast.
I would assume the OEM would've had some sort of wick in the oil cups to slowly drip the oil.? I agree with you on the total loss system and the purpose of applying oil each time it is used.
