The Atlas TH54 10F lathe
After some searching on Craigslist and other sale ads I finally landed an Atlas Lathe. The machine as I found it had no tooling and instead of a compound slide and cross slide had some sort of T slotted table. Well the price was right and I could not pass it up for better or worse. (Hmmm ... that sounds a lot like being married doesn't it?)
This section of the website will detail what i done to recondition or fix the lathe. Notice I did not say restore the machine, although along the way she did get some new parts. So hang out and follow along as I get Bertha back in running order and hopefully start making things with the machine.
Below are the videos I made while doing the work on the lathe. At the bottom of the page I will make available the related documents I have found for the machine in the event that a new user does not want to round them all up. These documents are available on a number of sites on the Internet, but I thought it would be a nice repository for them nonetheless. If you have some documentation relating to the Atlas Lathe that I am missing, please email me and and let me know as I would like to gather as much as possible and place them here.
The Lathe Reconditioning / Cleaning / or Whatever it was that I done
Atlas 10F Lathe - 01 - Introduction
Having just recently bought an Atlas TH54 lathe, I thought I would give a quick walk through and talk a little bit about the machine. This isn't probably the best condition machine, but for the little money that I had, I am glad to have it. I will post more videos of this machine covering the setup and some of the repairs that need to be made.

In this video I re-install the headstock spindle on the Atlas Lathe. I talk about the installation as well as how the pulley, bull gear and drive gear interact with the back gears. You get it all, even my goofs!!!
Atlas 10F Lathe - 04 - Backgear Disassembly and Shim Calculation
In this video I discuss how the back gears are disassembled and the process I went through to determine what size shims I needed between the Head stock castings and the back gear castings to set the proper clearance for the gears. Please note that I made an error in how I performed this but later caught my mistake and corrected it. I will annotate the video where I goofed. I decided to leave it there because I am much less than perfect and am a neophyte hobby machinist.
Atlas 10F Lathe - 05 - Counter Shaft Modifications
This video describes the modifications that were made to my 10F lathe by a previous owner. To me, this seems like a good modification. That is if you are only concerned with running the machine and not restoring it to original.

Also, I present the Dark Side of the Moon for your viewing pleasure. If you have not done so, I encourage you to check out Rich's channel, "Makin Somthin From Nothin". Rich has been very helpful to me on my lathe project and has a Number of machining and casting videos which I think are worth a look. Please pay him a visit. You can find him at https://www.youtube.com/channel/UCsuJ...
