Rotary Table Centreing

Hi Bernd
I have a bit of personal tuition arranged with the illustrious Dave Stilldrillin later on this week.
All, or at least the bit that's stuffed me for the time being, will be revealed ..

Great, It's good to get together, even a quick chat often helps to solve some problems even if you didn't know you had one :lol:

I don't have problems ....I don't need to .... I AM a problem in my own right ... :D :D or so my XYL said a few months ago, before departing in a huff.
Still, lifes got a bit less expensive of late. Clouds and silver linings an' all that ... :lol:

Darren:
MY turn now..... :)
I thought I understood this, but I now realise that I don't..... :scratch:
If you use a clock to center the RT as shown by Stew earlier, surely all you are doing is centring the work piece to the RT itself?
How do you find the centre of the RT and position it to the mill quill centre to set the table zero's.
What am I missing here :scratch:

You've two centers to think about
1:- The centre of the RT it self you can do this any where as I demonstrated on that link, what you,re doing is getting the work on the centre line of the RT
2:- Finding the centre of the RT in relation with the centre of the mill quill, you do this by putting a finger DTI in the mill chuck and rotating it around a datum thats centered on the RT, you move the X and Y axis on the mill until you have no movement on the clock so this shows that the centerline of the mill quill is on the same centre line of the RT. Then you just Zero the dials/DRO on the mill then you can index the off sets to give you pitch circle diameter of holes slot or what aver feature you want to produce.
If you've got something set up on you RT like the adaptor plate I made and the M2 screwed adaptor you made, when you put the chuck on this its automaticaly on the RT centre line so you can skip action 1 above:- In this instance you can treat it like a lathe
Hope this makes sense
