Cheap but good torque wrench recommendation(s)?

[guerney]

Can anyone suggest an inexpensive but reasonably good quality torque wrench? Somewhere on my bbs01b motor, something is making a slight creaking noise, and I'd like to apply more precise torque than my current "Yep, that'll do" guesstimates.

For accessible/straightforward locations, I have in the past used a long extension pipe over a socket handle thing and hung a weight off the end. For example, a 1 metre arm and 4 litres of water in a 5l plastic container is near enough 40Nm.

I like it! How long would the pipe need to be to move the world Archimedes? For accessibility, I might just buy this cheapo:

Improvisation is often the victim of reasonably priced stuff. I was anticipating a short spanner and a pumpkin making a joint appearance!

Unfortunately, growing a pumpkin to exactly 4kg is beyond my current pumpkin growing skills! But I could of course hack a bit off, before skewering it with the pipe...

No good for a bike. At 30Nm the lowest torque setting is way too much for a lot of bike fixings.

Good point! I'd better consult the Bafang bbs01b manual... oh wait, there is no bbs01b manual. But in the manual for the bbs01, the lowest torque mentioned is "20nm to 30nm":

Maybe I should buy two torque wrenches, one for 5-25nm and another for above 30nm... but there's this one which is 10nm to 80nm in 3/8" Square:

its only the crank arms that need above 30nm so prob a waste of money as mine have never fell of as do them up as tight as i can.

 

[guerney]

Which bike parts need 3nm? This one is 3nm to 12nm:

Pardon our interruption...

 

[guerney]

This one starts low 7Nm-112Nm, might be the one? £38.89 squids:

1-5nm will be for handle bar stuff like shifters ect but dont use mine for that and only use it for the axles and pivot bolts on the frame.

Thanks! I'm happy to use my usual manual vague torque measuring method for that small stuff.

What size drive have your sockets got? Best to check the proposed torque wrench will fit

I just use a hex set and spanners. I have a very small socket set I bought in Poundland many years ago, back when it was better, therefore I don't mind buying a big new set...the combination should last years: Does anyone have any recommendations for an inexpensive but good socket set in 3/8" for the Park Tool?

I'm certainly not buying these for £47 squids
