I have repaired office machines since 1975... my entire life

I believe most experienced techs get a feeling for how tight to make stuff..

max torque is sometimes a bad idea, the next service trip may make it impossible to get whatever apart....

frankly i hate stuff thats been over torqued.

I have had dumb customers tell me with pride i always know when allen screws are tight, they make that click click click sound.

lucky me has to drill out the allens or in some cases use my sawzall to cut off shafts that i cant get apart

my goal is a quick low cost repair.....

idiots can make that impossible
