Early Atlas 10 Compound / Cross Slide Studs

 

I have an older Atlas 10C/D lathe with the earlier compound and cross slide with the two studs instead of the beveled pilot (or pintle).? I have been doing some basic turning and decided to put the milling attachment on and try that out.? Since the earlier compound does not have the pintle, a pintle is bolted on first before the mill is added.? In my case the studs were too long for the mill to seat properly so I removed a bit of the excess length.? The mill mounts fine, but now there's not enough thread engagement to re-mount the cross slide.

Measure twice, shorten once . . . I know.

Getting new studs is probably the easiest.? I've seen them on eBay but they seem very pricey for two studs.? Another thought was to possibly "upgrade" the compound and cross slide to one with the pintle.? Would this work with an older saddle?

I do have a photo album uploaded if anyone needs reference pictures ("Atlas 10C/D Lathe") - /g/atlas-craftsman/album?id=243476.

I bought a mill attachment a few years ago. Found it very disappointing. ?A few other people shared the same opinion. ?Maybe you will have better luck. That was for my 12 inch craftsman lathe.?

The studs are easy to get at if you drive the slide off the feed screw. ? If my memory still serves that is what you will find.?

Since I've effectively ruined the studs for anything else but fastening the milling attachment, I see two options to be able to turn again . . .

1. Get new studs - eBay?
2. Convert my compound and cross slide to a newer pintle version (if possible).? Maybe just new castings and re-use the cross feed thread and nut?

Jeff
 

Try calling Clausing. The number has been posted here recently by a couple of people. Might also be common hardware.?

Or do the conversion...?

Jeff:
Replace the entire cross slide and compound with parts from any newer 10" Atlas lathe. The cross slide dove is the same, so is the ACME screw, and you will get an all cast iron slide and compound.

You could even replace the entire carriage and apron. I did all of that to my '35 vintage Craftsman, even swapped out the 5/8" leadscrew for a 3/4" with power cross feed.

Raymond,

So I can get newer upper and lower swivel compound castings (I believe #10-301 and 10-302) and re-use my tool post slide, screw and hardware?? The pintle would make swapping between turning and milling a whole lot quicker and easier.

Jeff
 

Since you need them short I think I would turn half of a coupling nut round and drill the holes out to fit my new long reach nuts.

Yes! Here in my c. 1935 lathe in 2009. I bought this as a "basket case" partially disassembled and loaded with dust and rust, some parts in a cardboard box. I cleaned it up and repainted., added the 8" chuck and large grey belt/gear cover purchased separately.

Zoom in, the carriage/apron assembly is a single piece casting, the cross slide and compound are ZAMAK with the two pins and nuts as you have.



Compare that to it in 2015 turning a piece of Delrin for a trailer axle spring bushing. It sports a 3/4" leadscrew, 2-piece carriage/apron assembly, with power cross feed, cast iron cross slide and compound that fits on the "button," even has a QCTP.
 

Zoom in on carriage showing one of two side nuts securing compound. I know the pic is fuzzy, it's the best I have for this.

Note single piece carriage/apron, 5/8" diameter leadscrew, no power cross feed.
