Plans for lathe attachment that lets you "mill" on the lathe

[Brian Rupnow]

Looking for either plans that show how to make this fixture or pictures of finished ones installed on a lathe. My friend that is restoring the old Atlas lathe was interested when I told him about this, and then I couldn't find a picture to show him.---Brian

I have the plain Myford milling attachment.
I have not used it, but I assume it can be oriented in several different ways.

Looks like one Myford milling attachment has a swivel option.
I think I would prefer not to have a swivel, but there may be applications where it could be useful.

There is a picture (and part number) of a genuine Atlas one here:

Raglan appear to have copied or licensed it:

Have a sniff around vintagemachinery.org as they have extensive Atlas literature available for download.

Boxford made a nice one for their machines (https://www.lathes.co.uk/boxford/page4.html), so there might be a Southbend version () as the two marques had a lot of similarity.

A good search phrase is 'lathe vertical slide' or 'lathe milling slide' (https://www.metallatheaccessories.com/product-page/milling-attachment-mla-5).

The Myford swivelling one was used a lot with their dividing head. See: (https://www.lathes.co.uk/myford/page3.html)

I don't think there are many plans about for vertical slides as they require quite a bit of milling in their manufacture which makes them a bit of a chicken & egg subject. Usually bought which then allows you to do the milling for other items of tooling.

This is the Atlas 10-501, for their 10” & 12” lathes.
Shown are the MT3 endmill holders, held in the lathe spindle with a drawbar.
The double male end spigot I made so I could use it on my SB9.
These are well built, this one weighs 15 lbs.
When mounted on the crosslide they lack rigidity & are slow, & can’t take very deep cuts.
I’ve often wondered if I could use it to as a ball turning tool, as I haven’t used it since I purchased a mill.

I have a few where built a angle plate that bolt where the compound goes . The bolt compound to the other side angle plate.
Then apdaed a vise to the compound and made tool plate that also bolts compound.

This what working on the Millport under $100.00

Here the one way .
I do not remember how compound is bolted to cross slide on a Atlas lathe.
This works on most mini lathe and lathes using mill circler tee slote. .

A south bend has a tapper that bolt to plate very easy too. .

I had friend of family that with and just a lathe great steam engines with this type mill. The lathe was a change gear flat belt made per WW ONE.

My first mill Pamgram 400 lathe mill use for almost 10 years before getting a mill.

Today setting one on mini lathe for second mill. So I do not have to break down the setup on my other mill.

Hi Brian, had enough winter yet? We’re still stuck in the tail end of the polar vortex with lows around -30 in AB.
I downloaded these plans off the web out of a 1949 issue of Science And Mechanics before I got my mini mill.
The attached PDF is a bit scratchy but readable. It’s all from bar stock so no castings and I think with careful layout and a little loctite it would make a very serviceable vertical slide.

You use compound slide.

I saw years ago on a mini lathe a guy used a heavy angle iron. (2½"x2½"x¼" angle iron)
Drill holes to fit the compound and lathe.
Use the to machine the angle square. This was done buy a simply fly cutter made for the job.

First bolted the angle to where compound was . Then flip around giving and machining the other side a true 90°
