Trimmed additional SYMMCO SF-610-6 bearing barrels on mini lathe. Found that a length of 0.290 inches is a good starting place for the welded aileron pushrod. Trimmed several too short. Machinists blueing doesnt stick to the Oillite bearings. Used a parting tool in the mini lathe, chucked the barrel end, supporting flange end with center. Thin bronze flash left on workpiece after parting tool breakthrough. Broke bronze with a small part of diagonal cutters. Filed flashing. Countersunk bearing ends with deburring tool.
