With just the basic body of the chuck (no jaws etc attached) when you wind the chuck in are the jaw slides supposed to meet in the middle with no gaps between them?



And if they are any idea what effect it has on the chuck if they don't?



Cheers

The manual specifically tells you that you can use the chuck like that to grasp tiny turnings, so one could assume the answer should be "yes".

How much are they off by?

the only time they came off was to give everything a good does of looking at & a good clean after I'd noticed the problem. And I made sure they went back in the right order but the problems still there.

They're each different, and you have to put them back on in the right order. ^^^^^^^^^^^^^ I've never actually tried it, but, logically, if you put the jaws back in the wrong order, they would have to be off by at least a whole tooth pitch, and the problem would be so severe you would not even think it might be within spec.

I took the chcuk back to where i got it yesterday and the bloke behind the counter said "it shouldn't be like that" and swapped it straight away.

With four slides, if you swap two adjacent ones they'd only be off by

1/2 pitch. The four are offset at 0, 1/4, 1/2, and 3/4 pitch.

But yeah, it would still be highly noticeable.
