This is a 3D CAD model of the Atlas 618 lathe that was generated by taking apart Atlas 618 serial number 011120 and manually measuring each part. It is what it is. The PDF assembly drawing and 3D model assembly STEP files have been placed in a compressed Zip file archive, which is 29 MB in size. Contents of the ReadMe file follow the model image below.

******* Readme File for Atlas 618 RS Lathe - ASSY Zip Archive Rev 001 *******
This Zip archive file contains a 3D model of the Atlas 618 lathe serial number
011120. This lathe was built after 1945 and before 1950, best guess 1947. It
is presented in STEP file format.
This is a full assembly model containing all the subassemblies and individual
part models, including hardware like screws, nuts, and washers.
The STEP file is a fairly large. Once extracted from the Zip archive and
decompressed it will be something like 87 MB in size. The assembly model
contains 226 unique component parts and 24 subassemblies.
It is offered as-is. It has been translated into the STEP format because this
is an almost universal format that is readable by nearly every CAD progam.
This is the only format I plan to release.
You may do with it as you wish. This includes figuring out how to load it and
save it in the native format of your own CAD system and fix the errors that may
arise in that process. Best wishes for a successful conversion.

For the purpose of illustration, below is the process that I use in my own CAD
program to convert a STEP file to my native CAD format, using "Atlas 618 RS Lathe
- ASSY - Rev A.zip" as an example:
1) Create a new folder for the model. Let's call it "Atlas 618 Lathe."
2) Move or copy "Atlas 618 RS Lathe - ASSY - Rev A.zip" to the new folder. At
this point it will be the only file in the folder.
3) Extract the compressed files from the Zip archive file to the "Atlas 618
Lathe" folder. This can usually be done by dragging and dropping. The folder
should now contain all the individual files that were in the Zip file plus the
Zip file itself.
4) Open the STEP file "Atlas 618 RS Lathe - ASSY - Rev A.STEP" with the CAD
program.
5) My CAD program now asks me to select a native format template file for part
models. This acts like a seed file. What that means, for example, is if the
template file material is PLAIN CARBON STEEL, all the parts will have that
property, even the o-rings. Every native format part will have the exact same
properties as the template/seed file.
6) My CAD program asks me to select a native format template file for assembly
models. This also acts like a seed file.
7) Wait for the CAD program to parse the file and create part and assembly
models. STEP files are text files and can be opened with any text editor.
This one is over a million lines long and may take a while to parse.
8) Repair faulty faces and gaps if necessary. Start by pressing the button
labeled "Attempt to Heal All." Proceed from there as needed.
9) Save the resulting models in the CAD program's native format.
That is how I do it in my CAD software. Your experience may vary.

This may prove handy in understanding how the various parts and subassemblies
relate to one another.
