So I got myself a new torq wrench as my old one has served me for many years and it was cheaper to buy a new one than to get it recalibrated.

 

Now here is my question I just happen to read the instructions and it says for Nm that each notch on the handle is equivalent to 1.36Nm so if you want 100Nm it's says to line up the middle 0 to the 94.9Nm mark then move it to number 4 (each one of the 4 notches at 1.36Nm) so 94.9Nm + 1.36Nm (4 times) would be 100.34Nm.

I used to just put the middle 0 on the closest whole number for and rotate the notch wound however many I required. For example if I wanted 110Nm I would set it to 122 then back it off 12 notches. 

Would it better better to convert the Nm to Foot pounds as they are whole numbers on the wrench so iffor example I wanted 104 Foot pounds I just line the middle 0 at the 100 mark and then rotate it to notch 4 to get 104.

 

What method do you fellas use Nm or Foot Pounds? 

That sounds horrendous and that it is actually a ft lbs device?

Would love to see the description/photo.

I always use Nm being a SI sort of Guy.
I had (before I gave it to brother) a 50 yo Norbar torque wrench that I checked the calibration of with digital luggage scales and a ruler...it was still spot on (always left at zero when not in use)

Nm for me.  

Genuinely surprised you can still buy a torque wrench without both lb/ft and Nm readings.

"Snap" !!! 🤣

My long departed Grandmother bought me a Norbar torque wrench some 46 years ago for  my 18th Birthday. Back then I used to rebuild motorbike engines every other week 🤣

I still use it today, and last time I checked the calibration it was spot on.

Here is the description from the instructions.

It's the sealey ak624 it does have both Nm and ib/ft but the instructions are a little confusing.

That is just an old style imperial lb/ft torque wrench with the addition of a Nm scale engraved alongside.

The Micrometer part of the handle is still only scaled in Ib/ft, no wonder it is confusing to use. I'm afraid if that was mine it would be getting dumped in the scrap pile.

I would exchange it but I need it this week for a clutch job on my own car and another wouldn't be here in time. It is very confusing.

Does ford etis only use Nm? I think Haynes gives both values but need to double check.

 

 

What an awful design!  

I bought a couple of Halfords Advanced manual torque wrenches around 15 years ago.  Just one single dial to twist with an easy-to-read display for both Nm and lb/ft.  Had to buy two to get the range I needed, but would still rather do that than try to convert into 1.36's.

Ultimately a direct Nm to lb/ft conversion should be exactly the same, so if you have both shown in the Haynes or wherever then just stick to lb/ft instead.

Or make and laminate a spreadsheet with the conversions (But that's quite Geekish 🙃)!

I know. it's so confusing. The Haynes manual shows both so I will just go with the lb/ft values they show.

Good idea, maybe when I get some time I will make one and keep it in the tool box 👍

Just print this table as a quick reference:
