OK, so, this might not be the prettiest repair, rather than throw money away, I decided to go to my local
engineers merchants and bought some
RectorSeal Epoxy Putty for £4.15.
I'll add here, if I were to repeat this process, I'd try to allow more time, to let the product cure a bit longer, and to file down the surface a little neater.
Now, we ain't aiming for perfection here folks, nor are we aiming for fineart photography, we're aiming at getting to work in the morning.
The stripped sensor.
The stripped recess for the sensor.
The filled recess - the first attempt, putting the putty around the inside of the recess, didn't work well, it wouldn't stick, I dried the hole off with a hairdryer and went at it again, this time allowing the putty to form an lip over the top, which was filed flat after hardening.
Filed flat with a new thread tapped.
Temp sensor with a new thread, the end was filed down to make a smoother less jaggy tip than in this picture before re-fitting, the o-ring was removed while putting the new thread on.
