What's the correct procedure for refitting a taper-chuck?

Morse or Jacobs taper?

Morse should be inserted clean and slightly oily (just to prevent
rust), with the top of the taper chamfered or rebated so that driving
it out with a drift doesn't raise a burr. They never (if in reasonable
condition) give trouble,

Jacobs need nailing, welding or at least Loctite. Pain in the arse.
