Atlas Gear Cutting Attachment
In this 6 part video series, Mr. Pete will go through the processes and steps of building the Atlas Gear Cutting Attachment. The Gear Cutting Attachment will allow the lathe operator to cut gears on the lathe with the addition of the milling attachment. There are a few differnet sets of drawings available and can be downloaded below. The First set of drawing are by Joe Hildreth and are available as zip files containing PDF, PNG and the actual FreeCAD drawings. The Next set are the ones available from the internet and are from Atlas Press Company. The third set of drawings are from Casting Specialties Corp., a company that supplied castings and materials for school machine shops. (Note, I will add the missing plans I mentioned as soon as I can find them in my files.)
The following files are available from Joe Hildreth. They are zip files containing PDFs, PNG Images and FreeCAD files. Clicking on the images will allow you to download which ever you prefer. For those of you downloading the FreeCAD files, you will need to install additional workbenches. For example, A2 Assembly and Tech Draw.

Comment From Viewer Pekka
Joe
You chose to use the original V-shaped retaining groove in the sleeve instead of Lyle's suggestion for a flat bottomed slot.
As I explained in my comment in part 2 of the video, The purpose of the groove is to both retain the sleeve in place and to force it's shoulder up against the block.
The 1" dimension in the diagram for the block should show the hole for the grub screw offset just enough to have the screw press only on the inside edge of groove to remove the need for precision dimensions. Lyle identifies this as a manufacturing error in part 3, but I believe it to be intentional and correct.
As explained this same feature is used on camera lens T-mounts to sideload the attachments during assembly.
