... Avid uses a higher torque spec. 5nm should be plenty
to keep your stem and headset tight, but probably not in
Cameron Park.


It does but only if I smear some grit-laden toothpaste on
the fork tube before sliding on the stem. Not the paste for
electric brushing but the regular paste. What I am saying
is that 5nm feels like it's about to strip the aluminum
threads out.

I think I'd buy a torque meter. And use it :-)


Trying to be a minimalist I have a makeshift one that was
ridiculed here but when compared to pro gear is more accurate
than anything from a hardware sto A digital suitcase scale.
I can torque a screw to precisely 44 in-lbs. Not 42 or 46 but
exactly 44. Try that with one of those ratchet gizmos.


Yup, you can use a scale and a carefully measured length wrench
but it is hardly necessary as torque limits always seem to be
quite liberal. Shimano specifies 2 - 4 Nm (18 - 36 "lbs) for
brake disc attaching bolts. No need to get right down to the nth
degree.


I know. Just mentioned it because there are people here who
seriously think the suitcase scale method is inaccurate.

No, it's just dopey -- it's like using a nail and a hammer to remove
a chain rivet . . . oh wait. Never mind.


Both methods work fine. Until I got a digital scale as a present I used
a butcher "hook scale" which was just fine. As for the hammer and nail
that is how I opened scores of chains when I had used them up as a
university student. When all you have is a single room of 150sqft or
less and your monthly budget is $300 including rent, utilities, food,
books, beer and all you learn minimalist strategies quickly.

Well, unless your butcher's scale was carefully calibrated then you
really had no idea of the torque you were actually applying and a
chain tool costs as little as $4.83 (2017 dollars)....

Since about two years I am the proud owner of a chain breaker because it
was part of a PricePoint bike tool kit. I wish they had thrown in a T-25
driver instead because that can't easily be kludged. Do I get my chains
open any faster? Nope.

BTW you also need some rock or a sturdy surface and a steel nut, any old
nut, to lay the chain link onto so the pin flies into that. For that
purpose I used a chunk of railroad flat-bottom rail as an anvil which I
still have.
