3D model description

I recently purchased a Craftsman 109 lathe off of Craigslist. Unfortunately, not all of the gears were present. After a LOT of hunting, I finally found all of the information I needed to create DXFs for the gears at http://www.geargenerator.com/. After that, I cleaned up the files and imported them into Autodesk Inventor to generate the STLs for printing.

I have printed two of the gears so far and they mesh properly with the OEM versions. I recommend printing with a high infill (I did mine at 100% infill out of Atomic Filament PETG) as they will be subjected to some load during use.

User "phylo" suggested I add a TRANSPOSITION gear (37 tooth / 47 tooth) for cutting metric threads using an inch leadscrew. See this webpage for more information on transposition gears: http://conradhoffman.com/metricthreading.htm I have uploaded one of the photos from that website to illustrate the point.

I have also uploaded files for printing the lathe handles that control the leadscrew, etc.

I have provided all of the DXFs, Inventor files, and STLs.

NOTE: I highly doubt the banjo will function properly if printed. However, it should be fine if you either CNC it out of metal or do a "Lost PLA" sand casting on it.
