Reducing collet nut play by electroplating thread?

[BazParticipant @baz89810]

Send it back to Nikken and get the job done properly, all this bodging about is only going to prolong the problem, it’s broke, parts are available so it’s a no brainer, might be different if it’s 50 years old and you have to repair it as makers have gone bust etc.

Do you think Loctite could really stop the crack opening when torquing down the nut on the collet?

Well the force appears to be in tension so as I understand these glues, the best use-case.
As someone else said, little to lose, even if it doesn’t work, just a bit of anaerobic glue to clean up!

and considerably cheaper than a factory re-build!

I think this is the one, Adam:

Glue will be as efficient as chewing gum. 30MPa vs 1000-1500MPa, you do the math…

BUT … Loctite and similar anaerobic retainers do not really work as “Glue” … they are essentially ‘gap fillers’ … So,  in the mode to which I referred,  648 should do an admirable job.

If, however, you are decrying their use for glueing the edges of the crack together, then yes I agree.

Having dealt with cracked ER8, ER11 and ER16 spindles, plating the thread must be worth a try, but suspect the damage is now done.

 

Good luck with it and let us know what improvements are achieved.
