Thanks in advance!!!!!!

I have two Norbar torque wrenches;

One is about 4ft long and gets used on big bolts on steelwork
(and to get the front spocket nut off the Dr. Zed)

The one I use working on the bike is a Norbar SL1

an older version of this NORBAR SL1 TORQUE WRENCH 1/2" DRIVE 5-40LBF.FT 8-54 NM on eBay (end time 03-Apr-10 14:08:14 BST)

there are lots of sizes and few that do every torque, coming in small medium and large. an 8-60Nm will be a good start but what about your wheel nuts and sprocket nut as said? the wheel nut on my triumph was 130Nm!!

i use a cheapo spring/ball detente type from argos, it was only £20 but probably gone up by now. i tested it at work and its accurate so theres no point spending megabucks on a DIY tool. just remember to always back off the spring when your finished with it, spring compression is the biggest cause of trouble with that type of torque wrench.

torsion wrenches dont have that problem, using the bend in a torsion bar of known strength to turn a needle on a gauge, sometimes read as degrees of bend. these are usually small wrenches and folks screw them up by using them on too high a torque, permanently bending the torsion bar. they can also be had quite cheap and i could do with one because my big'un doesnt go down low enough for a lot of smaller but critical parts.
dial wrenches are the most accurate but also the most expensive.
at least you know your getting decent quality from halfords, and a lifetime warranty. try and get a trade card and get a good deal.

ha! is that a coincidence or what? just got a card throught the door from halfords that says with my trade card their three wrenches are
8-60Nm £39.99
40-200Nm £39.99
60-300Nm £47.99

Fantastic coincidence Dasato Now i need to find someone with a card to get it for me :( .

Do you think the prices would be for any card holder or it is an offer for you particularly?

no its for halfords "trade card" holders only, if youre a mechanic or anything vaguely that uses tools (im a helicopter engineer) take your payslip in and register for a card, then you can get monster deals on parts and tools. oil filters and spark plugs for a quid, wiper blades for a fiver, that kind of thing, and big deals on their professional tools like those torque wrenches. theyre doing a big 120 piece socket and combi spanner set for £80 at the mo, thats £100 off retail.

if you cant get hold of one i'd be happy to buy it and send it to you, it might be a fiver for postage but its still £15 off. pay me through paypal or whatever, i'll PM you my email address if your interested i'll be going up there for some oil this weekend but might not look in Hubb for a bit

il try to get the card :) i know greedy

if not il get back to you. Your help is appreciated

I just we nnt o lidel they had 1 did for my bandit 1250 quite a good price too

worth looking on line at lidel

My camper needs 400Nm for the wheel nuts, which usually means pull fairly b%+*&y hard. But I was wondering about a fishing scales on the end of a metre scaffold pole I already have. 40kg on the scale at a meter distance = 400Nm. Fishing scales being cheaper and smaller than a torque wrench, and since some may argue a torque wrench is inaccurate unless just calibrated, so near enough?

Great theorising grizzly but with a vehicle like that you just need a quality socket and bar, then use the metre length of scaffold to do it up FT! Assuming you're dealing with steel wheels, brute force is all you need imho. :smartass:

Only two torque settings needed with this method

(1) A grunt tight

(2) A grunt and a fart tight

Nicely put. Or squeak and double squeak.
In truth, if you're dealing with a truck with sprung wheel rims, then correct torque settings on the wheel nuts are vital, but most vans just need grunt/fart or squeak/squeak. :cool4:

Geoff

not quite, a kilogramme/force is 9.81 Newtons so 40 kgf/m will be 392Nm. but yes, if your socket set includes a scaffold pole then thats close enough
:eek3:

This is true. So why do Ford provide a 1ft long wheelbrace for my 3.5t Transit ?:thumbdown:

our peugeot van at work came with an extending wheel brace that was a great bit of kit, went from a foot to three feet and had a reversible 17/19mm socket on the end.
needless to say it disappeared within a week.......

Because the only available space to store it was 12 inches long!!
Seriously though, a real triumph of hope over reality.
