I take ya up on that if I can't get it tonight. I am stopping at Napa on the way home and picking up a crocus cloth or emery paper.
go to
www.sinclairintl.com and I have a mouth expander die. Basically to turn the necks, you have to open the mouth on the brass a tad more than your expander ball does on a FL sizer die.
