This is the apron from my 11" SB 1934.
The piece wher the Thrad dial secures has always been broken since I got it 25 years ago.
When i got the lathe I dint have the skill to repair so good sense made me leave it alone.
Lately I decided to rebuild the lathe again and I wanted to fix the TD area since I found a TD for it.
I have soldered in my business daily for the past 20 years and thought I would take a stab at it on cast iron.
After talking with Dennis Turk I decided to try it on.
I belive the reair is good and will be there always.
I fitted a piece of CF 1018 int the broken area after good clean up and filing and polishing of the area.
After fluxing and heathing the cast I applied the flux to the polished area before I contaimanted it with more carbon. I saw the solder would stick to the polished cast then I applied my fitted 1018 fluxed piece to it and it soldered into place.
After cooling I clean all flux off and filed to shape the new piece, and drilled and tapped the hole to original location.
But instead of using a bolt I made a stud with searated nut so the stud can be loctited into place and only the nut for turning in and out.
I hope My pictures load for you , Photo bucket is new to me.

You may have to change your desktop down to 75% if pictures are too large to view? scroll left to right.
The 7.5" 4 jaw union chuck has a back plate of 1 5/8" and I refinished the chuck.
If I can find pictures of how it looked when I got it , its a different story. Now is a useable tool. Was a bucket of rust.
 
Hello Gary, used 45% silver solder and I like the brown flux other than the handy flux, as it lends it self to a higher temperture it seems before burning and scaling.
Some would have brazed it, I never liked brazing as I saw a lot of it fail to hold.

Found a couple pictures of the chuck as I found it, I was going to slavage the backplate but upon farther inspection I found it looked worse than is was.
In my opinion the backing plate just needs a little cleaning.
The four jaw has been abused (chipped jaw) but with some cleaning probably could be made serviceable.

The jaw was not chipped, I thought it was also from the pictures but when I received it, it was chalk of paint? The jaws are hardened .
See the pictures of it finished, mostly on the smooth surfaces needed only buffing and scotch brite, on the rough cast parts I bead blasted it clean.
the screws only needed a low speed buffing that all, the jaws I buffed and gun blued them.
I built a low speed buffer, ( 450 rpm) for rust bluing, works good for putting a satin sheen on surface rusted metals.
