Well done to ALL posters
It soon became useful and entertaining. There are regular posters, people who add useful info occasionally and plenty more who drop by to watch. That's fine. If you want to add news/comments it's easy to register and become a member.
RULES No personal insults. No swearing.
not resolvedI was considering purchasing a torque wrench, as I've a nasy habit of over-tightening anything that comes my way in terms of bolts.
Bicycle-specific ones seem to be quite an investment and I've found this one for motorbikes that looks to have a suitable range of 4-24 Nm. Can anyone who is more knowledgable on the subject advise me if I should pay a bit more and get one from Park Tool or if this will do the job?
For bicycle use it 'aint gonna take much of a hammering so any of them will do. The Draper ones are ok I've used one for my van for years with no problems. They sometimes sell 'em at lidl. Or these ones from screwfix are also ok. http://www.screwfix.com/prods/18289/Hand-Tools/Spanners-Wrenches/Wrenches/Reversible-Torque-Wrench?cm_mmc=GoogleBase-_-Datafeed-_-Hand%20Tools-_-Reversible%20%22%20Torque%20Wrench
My concern is that some of the more "industrial" ones - such as Screwfix's with a selectable range of 28-210Nm - will have destroyed my stem and headset long before it even registers on their minimum setting :)
I have been looking at the range from Parker International, but can't decide how much I am willing to spend.
Mine is a gert big Halfords Professional and goes from 40-200 Nm (about 30-150 lbft). On my bike, the only thing that goes significantly into that range is ISIS crank bolts, at about 85 lbft, and I don't use it in a calibrated sense for anything else on the bike. The length of the wrench is nicely handy when installing and tightening bottom bracket cups, as long as one 'feels' for the correct resistance.
The sensation of when a bolt or a nut is "tight enough" only really comes from experience, rather than dialling up a preset torque and cranking until the ratchet cuts in. Having said that, a small torque wrench might be useful in order to gain that experience.
I need something to help me tell the difference between "tighten to 4Nm" and "tighten to 8Nm"!
Something like http://www.parker-international.co.uk/7078/BBB-TorqueFix-Torque-Wrench.html or this http://www.parker-international.co.uk/7553/Pro-Torque-Wrench-.html (I can't decide which), d'you mean...
In my motorised vehicle life I use two Laser torque wrenches, one large one for cars, Landrovers etc and a small one for motorbikes and similar. I would suggest a look at machinemart here: http://www.machinemart.co.uk/shop/product/details/laser-torque-wrench-5-25nm-quarter-inch-driv
Has worked well for me, although I've never felt the need to use it on a bicycle!
Always remember to store your wrench wound out so there is no pressure on the spring though ;-)

I have got that one. Seems to be okay as far I can tell.
I've got both the Park tools "needle dial" wrenches (for want of a better term). I just checked though and they are *much* more expensive than I remember paying!
What's worse is that I hardly ever use them - certainly not for small bolts. It's more important to use loctite if you ask me.
