True, its not 'Snap On" quality but seems to do the job nicely and it fits with other tools under the seat. I guess I'm a bit naughty as I don't torque things up......... probably more guilty of over tightening I suspect.

They are not cheap, but its worth investing in one IMO, I've found mine so useful on some many ocassions over the years
Nothing to do.............all day to do it....I love retirement :lol:

i use torque wrench sometimes, not others. after 47 yrs of doing up bolts, think torque/tension is built into me. did up rear axle by feel, i was around 3ft/lbs out. not too bad i thought. i have some socket extensions, each is set at tension /torque. use with rattle gun, impact gun if you must know. 65, 75, 90 &110 ft/lbs. they are spot on. https://www.ebay.com.au/itm/8PC-1-2-Dr-TORQUE-EXTENSION-BAR-SOCKETS-THIN-WALL/291712685548?hash=item43eb6e55ec:g:IMEAAOxyZw5RZPBo

I'm the same as Grog with ref. using a torque wrench.
I think after years and years of playing with bikes you get a feel for how tight is tight enough. I still however always use one when I refit the 8 cam cover bolts as they are so easily stripped. I also use one for the rear wheel axle nut and that's about it.

Interesting stuff!!   I'm planning to have both wheels off this weekend to get new tyres fitted...and had thought that I would clean up the wheel whilst I was at it (as well as service the front calipers change pads etc etc)... had planned to remove the discs so that I could clean in those bits difficult to get to with the discs on.   But having read all this I'm now reconsidering taking the discs off.   Should be OK as long as I make sure they go back on the same way right?   Or anything else I should consider?

@ARH
Just make sure everything is clean before refitting the discs. Keep them on the same side they were originally fitted to. Also a dab of threadlock on each disc bolt and all should be ok👍

I wouldn't take the discs off for cleaning as you can get to everything without them off. If you do take them off, you should clean the wheel threads and bolt threads from old thread lock. The discs need to be on when wheels are balanced. Take the existing balance weights off before you bring the wheels to the shop. Check the wheels/tires when you receive them back. My front tire was mounted incorrectly - arrow on tire pointed opposite direction from wheel tire (not the only one to whom this happened).

Cheers Andre, Froudy.
I knew about balancing with the discs on, but didn't think about removing the old weights.... good tip!  I'll see immediately if the wheels been rebalanced  :onya:

Andre

They usually remove the old weights in the shop. But the previous time they left quite a bit on (all the glue and part of the rubber). I might take pics of my wheels next time to have something in case they seriously scratch stuff. Never know but last time they disappointed me threefold.

I hate removing the residue from balancing weights.
I usually soften with white spirit and then use an old, blunt disposable plastic knife. I doesn't damage or mark the rims.

Borrowed a Torque Wrench checked front axle. Tightened by 2 flats before tripping. So was happy old club fist wasnt far off. Pleased it didnt trip before it moved.
Another great day on the right side of the grass.😎
