A very worth while mod and just two things to add

While you have your pride and joy apart you could also think about mirror polishing
the mushroom as well, you will notice after you have how much smoother it will cock
and its quieter as well.

Secondly while you are there with your sears and block in pieces give the adjusting
screws a polish as well (the ends that is )it helps your fine adjustments no end.
