Re: Atlas / Craftsman 10F-12 10" & 12" Lathe Half Nuts / Split Nut
Speedoo51: I had considered that the actual threads in the brass were not accurate to the size of the half nuts.? Yes, when I was reworking my lathe I replaced my lead screw with less worn acme threads, so all these parts can vary the accuracy? of the threads.? Only the? half nuts and the position of the thread dial can tell you when to start your threads.? All good info.

I have the Atlas 10" lathe. I do not know what the center to center is,
but the bed length the carriage rides on is almost 36" from where it
meets the headstock to the end of the bed. In this group it had
previously been determined that it is of vintage 1957 or so.
I would like to replace the rocker tool holder with a quick change tool
holder. Can anyone recommend a good one for this lathe?

Re: Atlas / Craftsman 10F-12 10" & 12" Lathe Half Nuts / Split Nut
This is called “zinc pest” and is the result of the casting alloy (primarily zinc) having lead as an impurity. ’Tain’t s’posed to be any lead in there, but has been known to happen. In other words, this is an anomaly not something endemic to Zamak or other zinc-based alloys. The Zamak alloy used in our lathe parts is quite a strong & durable alloy. Check it out.

Hi Bill,
?
Not taking sides on this one
, but in my personal experience the Zamak parts do seem to
vary in terms of longevity .
Some years ago I imported the slotted shaft which operates
the half nuts from the OEM . . . it arrived in a sealed
packet , with what looked like a bit of talc powder to stop
it oxidising ?
Last year when I wanted to use it , it had disintegrated –
still in its sealed packet . . .
Keep well,

Anyone else who might be interested is also invited. Not everyone who plays with lathes and such is as interested in 3D printing as I am, so I started this group based on the comments of several members of the 7x12Minilathe group I also belong to.
