Re: Spindle register issue
I will do the experiment tomorrow night. I have 3 SB in the basement ( one is not powered, being in storage)toggle quoted messageShow quoted text
I will turn a piece and move it from lathe to lathe and take measurements.
I am quite sure the lathe with altered register will always be off.
We will see how repetitive readings will be.
I am a strong believer that the altered register has an effect on chuck Alignment. We will also see if the high point repeats as well.
I will publish results tomorrow.
In the meanwhile, the question about register rebuild is in the air.
Worst case scenario, the original 9A spindle will be back in commission until I find a viable solution

HTRL agrees with you (heresy around here, tho).
I'd be interested in an experiment.
Chuck up a short piece of scrap, turn the outside for a bit.
The part you just turned will be exactly concentric. Check it with an
Unmount/remount the chuck several times without removing the piece of
scrap. Each time check it with an indicator.
I really would be interested in the results, and would do the experiment
myself except that I don't have a chuck with a loose register.
