Im looking for a 1/2" drive bending beam torque wrench with a ft/lb scale on( i realise i can convert both the drive and the torque figure but why buy the wrong thing)

I only need 18ft/lbs but it cant be a clicky type wrench.

How ever when it comes to bending beam wrenches i can only find bargain basement 12.99 draper stuff - the park 3/8s "nm/inchpound" scale or 200 quid jobs.

Are there any middle of the road items that are not just rebadged 12.99 jobs ?

Or is it simply down to ease of manufacture and they are indeed worth about 12.99 to make.

http://www.amazon.co.uk/Draper-34487-2-Inch-Square-A-Type/dp/B0001K9T24

is the cheapo and ive seen the park tw2 for 40 quid which is the wrong drive and wrong scale how ever - its much smaller "range" - 0-50 ft lbs and in my mind more likely to be accurate than a 12.99 0-180 ft lb wrench ?

I have one but I can't think of the name of the manufacturer. I'll find out and post later.

They are called deflection torque wrenches

if your wanting one for Landrover timing belts for example - you can use the clicker type but practise with it until you know exactly where the 'click' happens.

Otherwise get yourself a dialtype torque wrench-similiar function to a deflection type but more accurate.

Honest question: are the clicky type not accurate then?

yes clicker types are accurate but not suitable for certain applications-and dont know the OPs application but for example on Defender engines you use a deflection or dial type torque wrench to put a certain amount of tension on the timing belt idler/adjuster before then locking it down in place.

It [i]is[/i] possible to use clicker/breaker type torque wrenches in this situation but it needs practise and familiarity of the 'breaking' point of your wrench. Better to use a dial type.

I've gone with the Park one + an adaptor to take it up to 1/2".

If you can wait I'll give you a lend.

All the 1/2" ones have far too small a scale to be useful at 15 Nm or whatever the tensioner needs.

EDIT: when I did the old 300tdi I just duct taped a kitchen scale to a 1/2" breaker bar, M=Fd and bob's your uncle. Certainly the cheapest way.

Couldn't be arsed with the faff this time around though...
