Torque Wrench - possible easy way to calibrate & check them

Seems as good and perhaps one of the better ways to check and calibrate them. Many of the cheaper ones are ok for occasional use, but often drift out after a short while or are quite inaccurate at the lower %10-20 of range.

The cheaper ones (like in the photo) that rely on measuring the deflection of the shaft shouldn't drift much as it's a physical property of the metal that's being measured. The pointer can move out of zero a bit, but it's an easy matter to bend it back to zero again.

Actual calibration can be a different matter though, but it really doesn't matter as it's easy to just use scales per the video to apply the force required and then just mark it on the scale.

Yep, the scale ones are much more accurate across the range and cheaper - but a pain to use as you need to be direct on sight which is not always easy.

Who uses torque wrenches???

Well, I've never used one so far, but many people do suggest following the guidelines when working on the bike - personally, I believe for the most part as long as things are tightened well enough and you do not over-tighten then fine, but best to get it right for wheels, etc.

I've just purchased a Draper 1/2" 30-210nM versions (half price at £24), 39mm socket (£18!) and 1/2" to 3/4" adapter for £52 all in - sucker or set for future work

(39MM for the clutch nut - didn't have a large enough adjustable spanner anyway, and 39mm clutch spanner was about £14 delivered)

For sure. I only use mine for the PCX, and didn't want to spent $100 to $200.

Me. I like to try and hit the "sweet spot" between "having it come undone whilst I'm out riding" and "stripping something".

Haven't been 100% successful at either in the past (although not on the PCX) ...
