Sounds like a sloppy fit and the ebonite is not held straight.

That's exactly what it was.

If it's rod, insert as close to the check as can get, I have a small chuck with center drill that I placed a wobbler on to make sure concentric then marked the MT with marker as to fit in rail stick same place each time

Once the rod spins at high RpM the center is clear , I sit in a chain so eye level and make sure nail center

The switch chuck to drill

Best to drill small the step up to size as can get chamfer with larger bits and first few mm of bore may be larger , another tip is drill 2mm in reverse as slow speed to start the bore then switch back

Different materials drill best at different speeds some need some lubricant that part is trial and error but don't force ease in, take out cool lubricant , brush off swarf the. Drill again

Should hit center every time

Otherwise your chuck is not true , a dial indicator will help, more then .0002 you got an issue , maybe bent pin jaw or simply chuck or insert not threaded complete to lathe stock

To add then loose Jaws and slip rod out to desired work space , if removing completely sometimes
I make and trade the pin jaws as to place back in same spot when rechucking
