I broke my friend's lathe, so I had to fix it!
I was using it to turn a 60* point to chuck into my drill press to aid in aligning a tap. Simple 10 minute job...
I turned and faced a suitable piece of small diameter round stock and then set the compound to 30* and tightened the nuts. I just nipped them up with the tiny wrench they supply but I still managed to strip the threads on one of the T-bolts. OK I thought - I should still be able to take light cuts with just one of the two done up. Yep - you guessed it - there goes the other thread
I cut the offending threads off and filed the bases flat. Found a couple of suitable M6x1 bolts to use and cut them to length. I then drilled and tapped the bases and staked the threads, so they wouldn't come loose. I wonder if he will know?
Original T-bolt above the donor thread and base:
