Torque

[Ame]

Good evening BCF
what would you consider 1.5 Nm of torque to 'feel' like? just over 'finger-tight' ?
If you made a scale from 1 to 6 Nm's,what would you say these 6 feel like?

[P.]

No idea, do stuff up till stuff doesn't fall off.

1 Nm is .737 Lb/ft 6Nm is 4.42 lb/ft
what is it you're doing that requires such a light touch?

The smallest bolt thread on most bikes is often 6mm which as rule of thumb
takes no more than 10 lb/ft ( 13.5 Nm)
Below this is what we call screws round here and from 6mm down
I use a driver rather than a socket and bar, possibly a small spanner.
I usually screw them in easily until they stop then 'nip' them up a bit.
My 'nip' and your 'nip' may vary, often its around 45 perhaps 90 degrees
at a guess but it depends
(Material, amount of thread, if loctite is being used etc)

Torque wrench?
we don' need no stinkin torque wrench.

1nm ≈ 1m x 100g.
So a similar force on a 30cm ratchet handle to that required to hold a half kilo bag of sugar.

just looking for the highest to lowest torque settings:

Rear axle nut 93 (9.5, 69) NOTE 4
Driven sprocket nut 32 (3.3, 24) NOTE 4
Swingarm pivot nut 88 (9.0, 65)


Carburetor drain screw 1.5 (0.15, 1.1)
Float chamber screw 2.1 (0.21, 1.5)
Slow jet 1.8 (0.18, 1.3)
Needle jet holder 2.5 (0.25, 1.8)
Main jet 2.1 (0.21, 1.5)dl=0

Front master cylinder reservoir cap screw 1.5 (0.2, 1.1)
Front brake light switch screw 1.2 (0.1, 0.9)

and wondering what these tiny increases can 'feel' like,taking into account different peoples 'nip'

is it generally accepted that 1.7 to 2.3 is 'fingertight'.so the NJH at 2.5 Nm [0.25,1.8] is about 45 degrees over this?


sorry it sounds garbled,

Very simple way to gauge micro torque:

Position one nut between one thumb and two or three fingers and very gently but progressively squeeze.
When the pain becomes unbearable, that's roughly in the region of 1/10th of a N·m.

Warning
Do not wait for a 'click' before stopping procedure.

Note:
Newton metres and family jewels are not "dimensionally equivalent" in the sense that they don't have the same expression in SI base units.

Hope this helps.
