So finally I got around to get a new 4-jaw chuck. It came with a backplate that mounts on the chuck.
The lathe I have, has 3 holes diameter 10mm located 120 degrees to eachother.
And a plug or and extruded part that goes inside the backplate.
I measured the spindle and it has about 0.002mm of deviations in x and z.
Now the new backplate does not have the correct size bolt threads to bolt it to the spindle nor has it the right size bore.
My question would be, what would be the correct order of operations to make a new plate from scratch.
And how would one go about measuring the diameter that the spindle holes are located?
Then I could atleast mount the 4-jaw to the machine and get some work done.
About the wrong bore, I think I can just mount the chuck backwards and dial it in.
I have more questions, but let's start with these first.
