Re: Concern with my Spindle
Hi everyone. I have a Craftsman Commercial 12”.? It has the Timken bearings - I know because I had it apart two weeks ago to fix the bull gear engagement pin. Another story for another day.?
Anyway, this thread has interested me for one reason, the oil cups. I always operated under the assumption that the purpose for the felt in the cups was to provide a constant drip to the bearings, as well as filter out any swarf from getting into the bearings through the oil supply. I never would have thought that the dust covers were meant to act as “seals” to retain so much oil around the bearings that it built up to the level of the felt cup.?
From what I’ve read in this thread, it seems that is the belief of some. I have never had any concern with my bearings getting oil, as I constantly fill the felts and have no reason to believe they’re not dripping into the bearings.?
My concern is this - when removing the spindle, it has to be driven toward the tailstock and the bull gear pulled rearward to dismount it from the woodruff key on the spindle. In order to get enough space, the woodruff key has to basically be driven into the inside front dust cover, denting it and causing the edge to become somewhat misshapen.?
The spindle is now back together, and everything is running tip top. The felts are doing their job, just as they always have. But there is absolutely no way the inner dust cover is going to be oil tight, especially after getting beaten up by the woodruff key. Should I really be expecting those dust covers to be holding oil up to the level of the cups? From what I’ve read, it sounds like some members’ lathes do? Or are the felts really just there to dispense the oil in a measured fashion?
Thanks,
Brad

Robert Downs ? ? 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: Missing Feed Gear Bolt
Jody,? Does it resemble this? I'd probably just make one but I? could for sure modify a regular carriage bolt. I took it off for entertainment and looked up specs. This is from my 3991 with qcgb but I? could make a 3/8-16×2 work. Turn the head down from .84 to .625, the thickness might not matter. Dave?

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. ? ?

Thanks for the warm welcome.
Here are a couple photos of their current condition.
The Atlas is complete and well oiled.
The Sears is covered in saw dust as it had been sitting in a wood shop
for years. There is no id plate, neither on the end nor the back. It is
complete except for a motor.
Both are sitting covered as I try to convert a 50x6 room along the front
of my house from a greenhouse to shop space.

have 2 bolts to hold the gear on.
I put the gears back in the position they were in when I first
got the lathe from my dad, so never noticed I'm missing a gear
bolt till last night.
The gear bolts have a thicker head on them versus a carriage
bolt, will I be OK using 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.
Thanks,
Jody

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.

Subject: Re: [atlas-craftsman IO] 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.?

Thanks.? Based on an assumption of constant production, it would have been made in late 1968.? However, if they were still selling as many in the 1960’s as they had in the 1940’s, they wouldn’t have stopped making them.? So it was made earlier, maybe in the early 1960’s. ? Robert Downs ?

Thanks for the warm welcome.
Here are a couple photos of their current condition.
The Atlas is complete and well oiled.
The Sears is covered in saw dust as it had been sitting in a wood shop
for years. There is no id plate, neither on the end nor the back. It is
complete except for a motor.
Both are sitting covered as I try to convert a 50x6 room along the front
of my house from a greenhouse to shop space.

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.

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. ? ?

Subject: Re: [atlas-craftsman IO] new guy - old 618? ??? ??? 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. ?
