I gave myself a promotion last week and now consider myself a "Semi-newbie" which is an upgrade from my previous "newbie" rank. Anyway here is my issue… I just began working on an F Kroeber movement (its mine). I ran it through the Ultrasonic cleaner for the first time and will begin bushing tomorrow. After cleaning I did an examination of the movement and discovered that the wheel which turns the slow/fast adjusting bar is in pretty bad shape (I don't know the correct names of the slow/fast adjusting bar or the wheel....maybe I shouldn't have given myself that promotion after all). My questions…What can be done about this wheel? Is there anything "I" can do myself (I do own a mini-lathe but have no idea how to cut a wheel).
