Sheldon 11-inch lathe progress - Part III: Tailstock Threads

Ok, I've realized that Super Glue has its place, but not where I used it on the lathe. My last post showed the tailstock screw insert that was just kind of floating in the spindle. I glued it in but the first time I tried extracting a chuck from the tailstock spindle, the threaded insert pulled free of the spindle. Soooooo, the option I chose was to repair what someone had previously done. There was a hole in the right end of the spindle that had been threaded at an angle to hold the insert in place but the both the insert and the 1/4-20 threads were damaged. I was able to drill the hole slightly larger and make new 5/16-18 threads, then insert a set screw. Here's the result:

That should hold things in place quite nicely. And me being a hobbyist, I'm sure it will last a long time.
