What... yes I have a need to use a torch on a lathe. More to the point the steady rest that came with my new to me 1952 SB 9" C lathe has a broken pivot eye. I'm not sure if it's a cast steel or iron. I've done the initial cleaning and prep for the repair, adding a reinforcement "rib". Next would be a thorough sand blasting of the eye's half of the part before torch work. I use Gasflux B flux and their CO4 brass.

Questions are about the cast nature and if iron or steel do I need greater consideration about heating then usual. Photos attached.

And the 3J collet chuck needs to find a home.

Back story- I have had a toy lathe (Atlas 6" Mk2) new from 1980. It has done a bunch of fun things but the less then robust construction finally got to me. It sold off Craig's list in 36 hours for over 75% of my cost, 40 years ago. AndyIMG_2441.jpgIMG_2443.jpg
