Micrometer Carriage Stop for Atlas lathe

9 Attachment(s)

After using a carriage stop that clamps to the edge of the flat ways of an Atlas lathe that never seems to be able to tighten enough to keep from cocking sideways I decided to make one that hooked over the ways.
The micrometer stops I've always seen have the micrometer in the center, but in trying to keep it as short as possible because it runs into the headstock I came up with this.

I'm not very good at documenting my builds because I am thinking about the next step rather than cameras so I didn't get any photos of the milling or the single point threading of the 5/16-40 threads or making the tap.

Centering with an old time wiggler that I made.

I didn't get any of the boring but here it is being tapped with the shop-built tap.

Next I cut a press fit plug for the end of the 1" aluminum tube that will later become the end cap and cut the taper.

Marking out 25 divisions on the barrel and the simple indexer that I used. Just a 100 tooth blade a section of square tubing shoulder bolted to the end of the bench and a small bungie cord. The tube just hangs along side the leg of the lathe with the bungie hooked in the end of the tube when not in use, the blade and mandrel get tossed in a drawer.

Hi Al
That's a pretty clever idea you have there, I think you done a wonderful job on the design and execution, not many people go to the extreme of making a dial and graduations, I do and I see you do as well, I love ingenuity, great job

Thanks, the biggest challenge on this job was single point threading on the un known stainless. I ended up threading at the second from top speed on the lathe about 1200 RPM any slower and it got stringy and gauled, let me tell you at that speed it doesn't take long to cut 3" of thread!

I use a long range indicator on the back of the carriage
