I have a threaded shaft with damage meaning the corresponding nut won't engage. I think it is just the top and one-two starting threads that are damaged.
Pics below.

It's about 14mm across (might be imperial) and most die sets I can find stop at M12. Never tried cutting new thread before and am a bit reluctant to have a first go at something I can't easily find a replacement for.

I've called a few engineering shops I can find and some might be able to assist by machining new thread.

Does it looks like something I could DIY with something I'm missing, or do a need a new one machined?
