Tell us about it Ross...Did you make a whole new nut or weld on a piece of spacer? In any event, the repair job looks great!
You must have run it by the buffer as well....

21 BenRom pedal steel guitars, a Nash 112 and a 1967 TOS Milling machine with many cutters making one hell of a mess on the floor.
the hardest part was getting the weld blob in there without the adjacent "fins" (about .040", 1mm thick) turning into a molten mess....that would've added a lot of extra work to the job! As you can see in the pic, one of the pointy tips on an adjacent ear burned back a bit..
I laid in the weld, machined the slots on either side of the blob the milled the front and rear of the repaired fin to match the profile of the others. I didn't have .093 ball end mill and was too impatient to order one and wait so using the other roller axle slots as a guide I very carefully drilled thru the repaired fin from the side, milled off the top, gave it a file stroke or two and sanded it with 60, 100, 220, and 400.
way more fun than the sheep fencing work I was playing hookey from
