Vehicle mechanic/grease monkey to trade, also got degree in mechanical engineering and i kinda specialised in stress n’ strain analysis, been building motorbikes/cars/pushbikes for as long as i can remember and i use one everyday but i do work in a bike shop and work methodically, it’s so i can hand a bike back to a customer will a clear mind than primarily for fear of over tightening any fastener – pretty much every bike we work on has very specific torque settings whether that be stem bolts, seatpost clamps, shock or linkage bushings, cranks etc…etc.
Would you be happy for a mechanic to do up your wheel nuts on the car with “do it up tight, then swing a bit more on the bar” mentality?.
You can get small torque drivers/ keys that are preset with a specific torque setting, these are very handy as owning a torque wrench is all well and good but they do need to be calibrated every so often as they have a varied torque range – and most folk forget to wind them back out to a zero torque setting thus rendering them pretty ineffectual/inaccurate over time.
