So instead of re-making the part, you could have just turned off the thread, then drilled/tapped for a bolt, and use a bolt + washer to hold it in place. I've definitely screwed up single-pointing the threads before on an arbor(for vastly different reasons), and just did that instead.
@@thumperthoughts I usually use 1/4-20 for things like this on bigger castings/a bigger lathe, and not had one snap off. Factory bolts are rolled, not cut, so they tend to be stronger, plus 12L14 isn't fantastic with threads. I usually use 12L14 for my arbors as well, but tap them instead of threading. One other suggestion, consider super glue or loctite(I tend to use 609, even though it isn't for this) on the arbor to help hold it in place! You'll find even after a few minutes it more than holds it's weight.

I was thinking the 5/16" diameter was too small for a decent size bolt, but you are correct, that would be another approach.
