Torque wrench / screwdriver

Hi Steve
If your scope is going on a PCP and you have a cordless drill with torque settings you can use that set on a lower setting like 1 or maybe 2, depends on your drill. Works for me, never had a scope fall of or move

I really do hope you are joking. I have no idea why you would use that over a finger tight allen key.

Also would that not work on a springer as well or are scopes and rails completely different on those?
 
Should work ok on a springer I guess, depends on how smooth or harsh it is and if you have stop screw, the drill on low setting is not as tight as you would think probably same as nipped with Allen key and they are all nice and even.
 
I agree with AO76 - Hawke recommended settings for their Weaver Match mounts are 3.4 Nm for the rail clamp screws and only 1.8 Nm for the top clamp screws. These are MAX figures, and there's no way you can know if your drill is achieving numbers as low as this. With the cost of some scopes and guns it's a ridiculous risk.
 
what about looking at one of these from Vector Air . was there last month and have been pondering 🤔 Do I need one 😁

I just use a cheap kamatsu torque driver from Amazon, it was maybe £30? I generally stick to 1nm under the specs to play it safe cept the rings, then I generally don’t go over 1.5 nm which seems not far over finger tight. hasn’t let me down yet touch wood.
 
Though I use an Effetto Mariposa torque wrench on my guns, I bought a Lidl one yesterday for £13 as a backup (and really for my bike). It’s marketed for bikes, and the torque range is 2-24 Nm. The lower limit is a fraction (but only a fraction) high for the small bolts on, say, a Sportsmatch mount, but otherwise fine for the rail ones and the majority of other things on an airgun. It’s got a selection of bits (inc 3 & 4mm Allen/hex). Tried it against my (about £200) Italian Swiss one and both agree within a fraction. It’s got a calibration certificate (not in Chinglish) and for the money seems a great set.

I read on the sport match mounts website when I looked into this and for my model they recommended:
15 in-lbs (1.7nm) For the ring clamps
55 in-lbs (6.2nm) For the dovetail clamps
They gave lower specs for other models like pic rails etc.

The torque drivers I recommend are from Wera. Use a load of their tools at work and seem to take the abuse pretty well. Sadly in this case they don't make a singe driver that covers both 1.7nm & 6.2nm so have to use these two: Wera 1 Wera 2 A bit rich for some maybe but personally I've had a couple of cheap £20-30 jobbys go twang under normal use back when I was a keen on bikes.
