Glen has explained this before,and it works well,If after the blade starts to tighten up,your an RCH to one side,tap on that side of the pivot pin,that will move the blade to the other side,couple taps at a time,your looking to move a 4 inch beam of sorts (at the tip) just a couple thou.at the pivot point.extrapolate that to the wedge end.it becomes alot of movement.
