This is a 3D CAD model of the Atlas 618 M6-39X Tool Post Assembly. It was created by measuring what came with my lathe. It is what it is. The PDF assembly drawing and 3D model assembly STEP files have been placed in a compressed Zip file archive. Contents of the ReadMe file follow the model image below.

***** Readme File for M6-39X RS - tool post - ASSY Zip Archive Rev 001 *****
This Zip archive file contains a 3D model of the Atlas 618 M6-39X RS Tool Post
Assembly. It was created by measuring the parts that came with my lathe.
There is no way of knowing whether or not it was made by Atlas. The dimensions
for the rocker, which was missing, were obtained by scaling photographs
obtained from Hobby-Machinist member Mill Lee Farm.
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 program.
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 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 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 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.
It 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.

Also included in the Zip archive file is the PDF drawing of the assembly.
This may prove handy in understanding how the various parts relate to one another.

of the lathe are available in PDF form on Hobby-Machinist.com in the following

FYI, I have almost no experience in dealing with surface-type solid models and
will not be able to support requests for help in solving problems with them. If
you are having difficulties, your best bet would be to find someone who uses
your CAD software and knows how to convert STEP files to your CAD's native
format and ask them for help.
