A 30 year hand at the nuke in Oswego showed me his tube rolling trick and I still use it
Back in 2019 I was on a boiler outage in Oswego and this old hand watched me fight a rolled tube for 20 minutes before he grabbed my expander and said "you're pushing, not rolling." He backed the torque off about a third and the tube seated clean on the next pass. Any of you run into that same deal where less pressure gets you a better roll?

Read somewhere that over torquing just work hardens the tube early.
