I have tried to use my old and trusty normal torque wrench this morning but it concerning me how much force is required to achieve 45nm. It does not owe me anything as I bought it in the early 90s. Can anyone recommend a sensibly priced new and accurate one? I was looking on eBay at britool mechanical ones but they are of unknown vintage and provenance. I have searched but not had many returns from the forum. thanks in advance for any suggestions
Halfords Advanced range. https://www.halfords.com/search?q=t...xNjQ5MjYkbzEkZzAkdDE3NTcxNjQ5MjYkajYwJGwwJGgw
Get yours calibrated, costs as little as £25 to £35. If it is beyond economical repair, Halfords Advanced tool range has a lifetime guarantee but any engineering supplier will have a range. Andy
Try and get yours checked as it’s probably going to be better quality that much of what you might buy today. I have four Teng, they are all in need of a check but I don’t know where to go, but I haven’t looked either.
I need some also. Both my barely used Sealey ones fell apart on the same day, infact I’ve had 3x sealey ones and they don’t last more than about 20 uses (yes I do take the torque off them after use)
I think it will be too old to repair the norbar if it needs it but I will check it out by trying to calibrate it myself. I think the britool mech ones might be a better bet. I have not done that before but it is not rocket science - famous last words!
Norbars are not expensive for what they are. And i wouldnt want to compromise on a torque wrench esp re calibration
The two norbars I have were bought in the 90’s - they may be ok I will check but the other issue is that the scale is viewed through a little window which is difficult to see through.
While on the guessing stick theme, don’t forget the guessing can get spectacularly random if the manufacturer does not specify (or you ignore) the method for reassembly, and ideally a temperature range. Imagine the different outcomes a torque of 45Nm applied at the fastener head could have on a thread smeared in copaslip, loctite, oiled or degreased and dry; with a plain/lock/wavy/dished washer or none; with a thread at 5 degC (cold garage) or 90 degC (warm engine) The good news is with the broad tolerances of mass production, it probably rarely matters on most elements of road bikes so long as you stay within a sensible range for the thread size and pitch, and the material of the fastener and the object being fastened.
