I have a Jet 13 x 40 lathe with apparent minor misalignment somewhere between the head-stock and/or chuck and longitudinal centerline. I have done some of the usual checks and adjustments and test cuts and now I have these questions.
1. Assuming the chuck is perfect but the head end is askew, how can I confirm this condition?
2. Assuming the head end is perfectly aligned, how can I tell the chuck is wonky?
3. If both chuck and head end are off, will grinding the jaws fix both issues at one time?
I have turned a piece of stock over about 12" of its length and my dial indicator shows about 2 thou variatio along that length - not too shabby. BUT initially, there was considerable eccentricity in the raw stock before turning, so how in the world do I find where the culprit lies?
I have also chucked up a piece of T G & P 1-3/4" dia and it shows run-out! Wa-a-a-a-ah!
I feel like the GEICO gekko with a flat tire - "Please - somebody help me!!!!"
(I'm near Monreo Michigan if you are hearing my cries)
