Steady Rest for Atlas / Craftsman 618 Lathe
I needed a steady rest for my old lathe. They're available on ebay but are like $300 and I couldn't justify spending that much on one for this lathe. I'd rather put that $ towards a newer more modern and rigid lathe. However I did need one to knock out a small project so I drew and printed one and threw on $20 worth of amazon parts.

Printed on a CR10-s5 with .8 nozzle. 3 walls 35% infill.
You'll have the clean up all corners with a file to make them fully square / flush on the lathe ways. The channels for the jaws/finger you might want to leave a little material to give a little tension not too tight but not sloppy either.
The jaws / fingers are held in place with m10 screws with m10 brass threaded heat sets inserts in the part.
the steadyrest and clamp block are secured on the lathe ways with a 3/8" bolt and nut with washer.
