What is running out? Headstock, or tailstock? I can't tell from the video. What I can tell is the entire center or arbor is running out. Make sure taper and center/arbor is clean, if it is in a taper. Need more info.

Hi

Rather a bit late for this but......

Is the lathe a Sieg model or clone?

If so,these are poor headstock runout due to incorrect headstock bearings from the factory ie they're normal bearings and should be changed to tapered bearings.

This will reduce the runout considerably.

Could be simple like your live center is bent or worn at chucking area. Maybe not enough live center shank in chuck. could be chuck jaws or screw is worn. Can try putting a piece of

cold roll or tool steel in chuck and check run out with mic. Just a try, Put live center in chuck and spin-Hit center tip towards chuck with plastic or lead hammer somes times this

will straighten center if chuck is loose or worn. This is for a 3 jaw self centering chuck

its like screw driver when use

Are you sure its not just a bent barrel on your tailstock ? I cant see what way round your camera is. Is the chuck to the left or right in the frame ?

what kind of spur drive is that......

[powershop1903]

Just mount a 3 jaw and grip some piece of junk stock. Turn a 60 degree centre on the chucked piece and use a drive dog to drive your actual workpiece.

Bent work holding...IE: Collet nose, collet or chuck jaws. put soft jaw in the chuck, bore them true and mount a part to see. take the part in and out to see if it repeats.

you may just need a new chuck. If it's a main bearing. it's a 2 day job.
