Nicely shown Dave, that's exactly what I do too. I can't remember if I learned it from a video, or from reading a machining site...

One thing to watch out for, especially if you've got an old & possibly abused lathe, is that your chuck jaws are actually holding straight - I've got quite a taper on my 4-jaw, so you end up with one bit rotating perfectly true, the rest is wobbling about like a spinning top! Maybe I should just buy some new chucks....

Excellent write up and by the way, I think you have the same DTI stands as I do and they are FANTASTIC and make setting up the DTI a joy rather than the struggle I use to find it!! I have since binned all my old standard magnetic ones!! OK, well I`ve not really, they are in the cupboard but you know what I mean!!

Hi,

Thank you all for your nice comments, and thanks to Tim for cleaning up the first mess I made of it.

Well, I'm not one to refuse praise, but it wasn't me who tidied up the old one, I think it was one of the other mods :thumbup:

If anything I helped to take the first one even further off-topic :doh: :lol:

Anyway, before I do the same on this thread, I must say thank you Dave for showing so well how you centre "stuff" in the 4jaw :bow: :bow:
