My question is; Did you wash the manufacturing oils and grease off the mandrels before you torched them the first time?

Ammonia, Dawn dish soap and Simply Green are good degreasers as is Break Clean, Carb Cleaner and Acetone Nail polish remover.

A good roughing up with sand paper, coarse steel wool or a metal file is a good idea too.

Once the oils are torched on to the mandrel it can get kind of glassy and it may take sand paper or a metal file to scrape off the cooked on oils so it's best to clean them before their heating.

Good Luck chasing up a fix.

Oh and file off the nibs where the cutters pinched the ends too.
Those nibs can gouge the flesh right off your fingers when you least expect it and hurts like hell.
Don't ask how I know this.
