Torque wrench on scope

Different manufacturers recommend different settings, but 1.7 N.m for the rings and 3.5 N.m for the rails is pretty typical. Thr ring setting is the important one, as you don’t want to crimp the tube. I have never seen a lower recommendation than 1.7, and I’ve never had a scope move when set at that torque on springers or PCP’s, so that’s what I use.

Is that tightening as tight as you can with the short side? I actually prefer the long side because it gives me more feel of the fittings tightening together, in no way do I just murder it up tight 😂

It only needs a tweak! Scopes can be damaged by over tightening and most don’t need anywhere near the amount of force they are put under😁

Fair enough, but ive never had one, never felt the need and never lost out over common sense. Dont think i know anyone who uses one either.

Gotta say I’m the same, never found the need for one. Finger tight and a tad extra has never let me down. I do though use feeler gauges to get the top part of the mounts seated correctly.
 
I bought a cheap torque wrench from Lidl a few years ago. It was a piece of 💩. I ended up over torquing scope mounts and damaged my rails. You get what you pay for. BE CAREFUL.

Yes, I definitely always tighten something as appropriate to the materials I'm tightening. I just find that more leverage offers more control and feel of the force you apply.

In a similar ish expression of this, would be using a short spanner to undo a very tight nut or bolt. You may manage to undo it, but it's likely you'll end with busted knuckles in the process, because you were unable to maintain control with a lack of leverage.
 
I have seen more damage done by torque wrench than by finger tight, unless your buying something that has a chance of passing a proper calibration test. Do the screw up with the short end until it tightens then a further 1/8 turn with the long end. Never damaged one yet. Have had one set of rings that was only threaded half way, wondering why the scope was still loose. Chinese quality control 🤣 and it came from another large land mass.
 
My Draper Torque Driver is in Newton Meters so the bases on my scopes are set at 3.4Nm and the ring caps are set at 1.3Nm which is equivalent to 30 in lbf for the bases and 11.5 in lbf for the ring caps.
 
For my BKLs I mount to gun wet and to 35 inch Ibs

The rings I use 15, nothing ever moves.

I put a felt pen mark where they are positioned.
 
I have a digital torque driver which I have owned for a few years, covers 0.25 to 6Nm. It was purchased for electronics maintenance and works well. But, used it a couple of times when mounting scopes and found that my hands gave me almost as accurate a feel in comparison. I have been using hand tools for most of my working life, so maybe just a learned skill.
 
I have a Torquleader 1/4 inch drive screwdriver, not specifically for scope mounts but i do use it for them now and them.
