Cheap bike torque wrench

[Bluebottle]

I'm not a fan of buying cheap tools but I saw this in Cla Ohlson in Manchester and thought it might be useful for somebody.

1/4 inch drive torque wrench, 2-24 NM so ideal for bikes £22.99
Can't say it looked the highest quality but looked adequate for the occasional DIY job

good price but at 24nm it would only be useful for tightening small nuts and screws you would normally nip up, the few items i use a torque wrench is for tranny and clutch and wheel nuts , engine mounting and shocks where the NM is above 80 and upwards.. and the variator which is 160 to 175NM

I've always found the smaller ones are harder to get hold of at a reasonable price than the more common big ones

very true, and to find a good make that does click when at the correct torque is important, especially when at lower torque settings as easier to shear the bolts, so great find... didnt mean owt by my last post Bluebottle, cheers

No probs, I wasn't having a go either, sorry if it sounded that way, wasn't meant to.

The click on those torque wrenches is a really elegant bit of design. When I was at School I tried to design a torque wrench and contacted the original manufacturers and they kindly sent me copies of the original patent, can't remember who came up with the break idea but its bloody clever.
There is a block that the spring tightens against but it has a corner missing so that it falls over when the torque is high enough to overcome the spring. Genius

My old torque wrench has a scale bolted to it and a non-bendy pointer runns parallel to the main shaft. It relies on the bendiness of the shaft to provide a reading!!!
None of this modern ratchet rubbish.

I was told I have plenty of that...but never have been able to work out what that means!

Finger tight plus 1/8th turn is my inbuilt torque settings for bolts into alloy. Maybe a bit more on wheel/spindle nuts. Only thing i've used a TW for is head bolts really.

Went on an update day with the institute of the Motor Industry (IMI) last year called something silly like "it's good to torque" and a talk/demonstration was given by a representative from Norbar. He reckoned that wherever you were in the world if you used a torque wrench that 'clicks', it is a Norbar or a Norbar licensed torque wrench and there would be no difference in the accuracy whatever name is on the bar. He reckons they (Norbar) invented the torque wrench for Rolls Royce.

It was definately Norbar who sent me the patent details so that all fits but I can't remember the name of the individual who came up with making using the tipping block, would be nice to credit the guy for some serious lateral thinking.
