High-performace gloves needed and sealed eyewear...

Goodness but I've stirred up a hornet's nest here!

The comments made about large diameter fine threads are especially interesting. I do not know whether my thread had a wee bit of swarf on it or not, certainly cannot rule that possibility out, before trying the mating parts together, even though I do try doing that as a routine but perhaps a wee bit was missed - it's not so easy to see everything part of it on an internal thread.  Would certainly explain what happened but if a bit of swarf was present.

So, ensuring that ALL bits of swarf however minute are thoroughly cleared off before trying the mating parts, along with the use of a good lubricant, is obviously a good practice to adopt for the future. Lesson well learned!

ATF was also mentioned as a lubricant, one that I had never considered before too.

One learns something new everyday!

Next you will be telling me to stop going round race tracks with my knee down with one hand on the bars whilst the back wheel is sliding and leaving black lines lines. because if you fall off it might hurt.......................... you dont say.

I fully expect to remove the parts from the lathe before I Anodise or Alocrom them, the lathe wont fit in the tank...
