Re: Atlas / Craftsman 10F-12 10" & 12" Lathe Half Nuts / Split Nut
Assuming that the threading dial gear is meshed with the lead screw threads, use the carriage traverse handwheel to bring the “1” on the dial ?around to the fixed index mark.? Engage the half nuts, using the handwheel to rock the carriage back and forth to find the engagement area.? After engaging the half-nuts, rock the carriage back and forth and confirm that the “1” mark moves approximately the same distance CW and CCW from the fixed mark.? There is some backlash in the system and the dial should be set in the middle of it as that is when you smartly lower the engagement lever, knowing that it will lower cleanly.? Doing it this way, it won’t matter whether you are threading toward the headstock or the tailstock. ? Robert Downs ?

Subject: Re: [atlas-craftsman IO] Atlas / Craftsman 10F-12 10" & 12" Lathe Half Nuts / Split Nut? Rexarino Feb 5 #102601
I used a spacer to make the lines on the thread dial assembly line up correctly after installing new half nuts from Clausing.
Regards,
Rex
Just for future reference, how do you know or what is the indication, that the dial is not in sink with the half nuts and would require a spacer?
Thanks, Ken H in AZ

James , ? Thanks for the clarification
A quick check on the Chronos , RDG , and other vendors based in the UK shows that a set similar to the one I pictured here goes for about $100 . . .? not sure how that compares , and excludes shipping of course .
I have the same style but much bigger on my large lathe , so they are / were not limited to Atlas etc size machines , ? Keep well, ? Carvel ?

Well, I had a Phase-II piston-style post on my Atlas 10" and later a
12", and it was just FINE.
Never once had a problem with repeatability or movement.? But,
perhaps some other brands of piston post may not be made that well.
I do have a wedge-style post on my 15" Sheldon, probably a wedge is
more appropriate for that size of lathe.

The nut can be turned on the lathe, as long as you are ok with a round nub sticking up through the compound slot rather than a square nub. You do need a four-jaw, though.? It’s pretty easy to do, and a fun little project if you’re just getting started on the lathe. The hardest part is getting the nut blank that comes with the QCTP chucked up true.?

File and bench vise are enough. If you don't want to sweat for it, angle grinder and vise. If you have a bandsaw and a file that will work too. Milling machine is always nice but not required.

If you have a hacksaw and a file or any tools more advanced that that, you can "machine" the T-nut.? My first QCTP I hadn't bought my mill yet so I did the T-nut with an angle grinder, a thin cut off wheel, a hard wheel and a flap wheel to clean up the finish.? It looked machined by the time I finished.? It's still on my Atlas-Craftsman 12x36.

I have a Phase II AXA piston type on my AC12x36, an A2Z CNC piston type aluminum QCTP on my AC6x18, a CDCO Bostar AXA wedge type on my South Bend 9A and a Bostar CXA wedge style on my South Bend 16".? I actually prefer the holders from CDCO over the Phase II as they fit tighter on the dovetails and seem to be more stable when clamped.? I also have noticed th Phase II piston type under a heavy cut does sometimes move a tiny bit which is something I never have seen on the wedge post.? One some early purchases of spare AXA blocks from CDCO i had to replace the Chinese eset screws as the hex socket stripped out but anything I"ve bought in the past 6 years hasn't had that issue.? ?The CXA tool post set is as rigid as any other I"ve seen including real Aloris posts.
I'm looking at some blocks both AXA and CXA from All Industrial that are called XL blocks and allow larger tooling to be clamped that the normal AXA 101 and 102 blocks allows.? The XL blocks for the CXA post will allow tool shanks of 1" square to be clamped as opposed to th 3/4" of the standard block.? There is a lot of large shank tooling out there at surplus pricing that I could use with tool holder blocks that holds larger shanks.
In the near future I'm going to replace the A2Z post with a OXA cast iron post set as I'm not pleased with the flexibility of the aluminum post set.? Plus A2Z is defunct and sooner or later supplies of blocks will dry up.? I know UI can make them myself but I'd rather spend my all too scarce shop time making parts for projects instead of making tooling I can buy down the street.? As it is my shop time is an hour here and two hours there stolen from either playing hooky from class or work or squeezed in between 11pm and 1am when I probably should be sleeping.

The MT3-2 sleeve allows you to use a variety of MT-2 tooling in the
spindle , and an MT-2 centre will also fit the tailstock . . . .
If you intend to do centre to centre operations then a MT-3 and an
MT-2 would be needed

Short answer is “yes”. A 3MT dead center will work fine in the spindle.

The manual for my Atlas 10" says a sleeve is provided to go from a #2
Morse taper to a #3 Morse taper. I know little about machining and so I
don't know if this means I could buy a #3 Morse dead center and directly
put it in the headstock spindle and eliminate the sleeve. Would I be
able to do this, or could there still be some problems in the taper of
the bought dead center not matching like it should to the taper in the
headstock?

I agree with Carvel.? The MT2 and MT3 are so cheap, get both.? I believe I also bought the MT3 to MT2 sleeve.

You are right about the Yuasa piston. It is the only one that i know of that is acceptable. For all other imports just get wedge.

In most Chinese cases I would agree with you.? But how badly depends upon the size and shape of the piston.? Most of the Chinese made piston-type tool posts have a very small round piston.? The Yuasa, which was I think the
first piston type made some 40 odd years ago, has a larger rectangular piston.? I bought one new 38 years ago (when the cost in 2019 Dollars was about three times what the CDCO one costs today) and have never felt that it was inferior to the wedge type.? Fortunately,
the holders will fit either type.

Kurt,
I looked in CDCO, cdcotools.com, but I cannot copy a link to the post
and tool holders because the page I am looking at doesn't have a link to
it. However, it is item #29461 and includes the quick change post and 5
tools holders. It is called
AXA Piston Type Tool Post for Lathe up to 12"
and in the description it specifically says it fits an Atlas 10" and 12"

I have the Atlas 10" lathe. I do not know what the center to center is,
but the bed length the carriage rides on is almost 36" from where it
meets the headstock to the end of the bed. In this group it had
previously been determined that it is of vintage 1957 or so.
I would like to replace the rocker tool holder with a quick change tool
holder. Can anyone recommend a good one for this lathe?

I also had to take mine apart and clean it up, but I think that is just expected with any import tooling, and yes, you will need to machine the t-nut.

AXA Wedge-type QCTP kit:
$129 plus shipping.
I am not endorsing this particular product or seller, just showing
that they can be had for little money in comparison to top-name brands
that are priced ten times higher.
The kit I have was similarly priced and it works great! I can't name
the seller because he closed his shop several years ago and is now
into other endeavors.

I dont recommend the postilion type tool post. The wedge type is a lot more solid

Must be a typo. 175-200 is average online
CDCO has an AXA wedge type but they are out of stock and the price is
$3,000.

Re: Atlas / Craftsman 10F-12 10" & 12" Lathe Half Nuts / Split Nut
Rexarino Feb 5 #102601
I used a spacer to make the lines on the thread dial assembly line up correctly after installing new half nuts from Clausing.
Regards,
Rex
Just for future reference, how do you know or what is the indication, that the dial is not in sink with the half nuts and would require a spacer?
Thanks, Ken H in AZ
