I've bought some old wooden molding planes during the past year, and before wrecking them I have a question: there is a metal depth stop that runs through the body to the sole. These seem totally stuck on all my planes. Is this metal depth stop meant to be adjustable at all? The irons themselves are adjustable for depth, but these depth stops (I am assuming they are depth stops) just don't budge at all. Any suggestions?
