The trouble with torquefingers is it takes a while to calibrate them, and you do this by stripping threads/breaking bolts. I have a full set but if I didn’t i’d be getting one of those little wrenches.
But anyway, the other thing is, don’t slavishly trust a torque wrench. A mate of mine bought one and became the king of krossthreadland overnight, it’s as if it switches off the part of the brain that says “This ain’t right”. It’s not clicked so keep going! The bars don’t feel tight but the wrench says they are so I’ll just go off this dropppaaaargh. It’s not a replacement for a bit of sense, just a useful addition.
