Chuck Undoing.
Hi Dave,
Are you using anything between the Chuck & the Head.
I just keep my Pieces Clean, & have only ever used Steel to Steel
When I want to remove my Chuck, I normally use my Knockout Bar, across the Jaws. So much easier than using my Tommy Bars, as that can Elongate the Chuck Holes in my Chuck anyway, & I can lock the Spindle, to do this.Regards,
issatree.

The Chuck.
Hi Again,
So what Lathe do you have Dave, & is it Variable.
My Lathe is a " Tough ", Variable now, & 3000 RPM to Zero in 3 Sec.
Never had any of my Chucks come loose though.
At a loss to know what is going on ?.Regards,
issatree.

the issue was on a HAFCO MC 900, now I have a NOVA 3000 (less then a week). Have not had much turning time on it yet, one project only. Noticed an immediate difference

Just screwing the chuck on finger tight can lead to the chuck unscrewing when switching the lathe off.
I seen this happen a couple of times at club events.
This problem is made worse with modern variable speed lathes that have electronic braking.
A large heavy lump of wood wants to keep spinning when the brake is applied.
The safest method of mounting the chuck onto the lathe spindle is to use the tommy bar to bump it up tight onto the spindle.
I use the palm of my hand to do this. It doesn't take much force.
With my Vicmarc key chucks I use the T bar.
For big bowl blanks I use the clamp supplied with my VL300 to make sure nothing takes off for a trip aroung the workshop.
Cheers

I have the nova 3000 upgraded to vs i put the chuck on with a light touch metal to metal ( keep the regestering faces clean ) then tighten the grub screw I have taped into the chuck insert it dose not loosen and comes of no trouble. If you use a washer the chuck will not run true as that is what the register is for unless you get a proper made washer then there is no point as it is still metal to metal. just my 2 cents for what it's worth. A i wash my chucks in kero it leaves a nice coating on the when dry.

I don't like that idea, any sort of a washer can 'pack' the chuck out from where it was supposed to seat square & true, I've heard blokes using a washer complain 'cos there expensive 'XYZ' brand chuck doesn't run true on their lathe.
I keep a small rubber mallet at the end of my lathe for this & all the cam locks, using your palm to bump it will eventually cause problems with your hand/wrist/arm.Cliff.

Yeah well, you can lead a horse to water etc.... there are already a couple of members on here who are suffering from that sort of injury, you might be just lucky.
