Winter has passed and I am now venturing out into the workshop again.

In my workshop I have an old Alfred Stewart Advance lathe serial number AW609 which was handed down to me from my grandfather around ten to fifteen years ago when he got his hands on a Myford Super 7. I had not had much use of it over the years as the last few places I have lived in I had no workshop so I had the lathe in storage.

Advance Lathe

When I moved into my current place I decided to get it set up again so I could start machining a few projects. I started doing a bit of research into the lathe as I had not known much about it. I stumbled across some great on-line resources for this lathe, it turns out the Advance was made in Melbourne Australia which I found interesting and it seems the design is loosely based around early Myford lathes, more info available at and Tooljunkie both excelent sites with a wealth of information.

It is a nice old lathe but has seen better days, I am now in the process of making repairs and improvements to the lathe.


My first addition to the lathe was a QCTP (Quick-Change Tool-Post). The previous 4-way tool-post didn’t allow me to place the tools low enough to find centre line, which I found very strange perhaps grandpa just whacked on any tool-post he could find when he gave the lathe to me. With the QCTP I can adjust the height below the level the old tool post would allow and can raise the level of the tool without using shims!!. I had thought about machining a few millimeters of the top of the compound slide to get a better height adjustment range, however I don’t have a milling machine (yet!).

I wanted to replace all the gib screws as some were broken and others replaced with odd screws also the apron kept working its way loose, everything is a bit worn and my cuts are not so smooth so I thought new screws might help a bit. I had a friend at work help me determine the threads used on the lathe, using a thread gauge and chart we determined the grub screws were 3/16″ BSW and the countersunk screws holding up the apron were 1/4″ BSW, we verified this using a 3/16″ BSW tap and a 1/4″ BSW tap. I have ordered new grub screws and locking nuts for the gib screws and some new screws for holding the apron from Ideally I would like to drill out the threads and re-tap them at a slightly larger diameter metric thread,  but this mod will have to wait for now as I have many other projects on the go.

I am also in the process of converting the lathe to variable speed. I have purchased a Reliance Electric single phase to 3-phase Variable Speed Drive (VSD), I now need to replace the single phase motor with a suitable 3-Phase motor then hook up the VSD.

I am also adding a digitial read-out (DRO) to the lathe, I have purchased digital-caliper-type linear scales which I plan to interface to my own DRO unit, all the parts have been ordered and I am currently awaiting the package to arrive. I have already designed and fabricated the PCB’s for the DRO but have not built them up yet. I will post some updates once I start working on adding this in, I need to investigate the best way to mount the scales securely without drilling too many holes in the lathe and with some form of swarf and cutting oil protection.

The accessories I have; 3-jaw chuck, 4-jaw chuck, face plate, steady rest, change gears, original tool holder and two spare back-plates. They could all do with a clean-up, the steady rest looks like a pretty rough job, at some stage I would like to make a new one from scratch.


If there is anyone else out there who is the owner of an Advance send me a message, perhaps we can share some tips or mod’s.
