Torque device for portable tool pack

[Dirtlaw]

Saw this and I couldn't resist. Accuracy is only 10%, but it's small size makes a torque device doable for your portable tool kit. From what I've read it's well made.

10% at small amounts really isn't much to worry about. Fix-It Sticks kits seem to be universally carried in every PRS match competitor's bag.

Interesting series of comparisons/tests in thie writeup:

You can get a bigger difference than 10% by how you use the tool.

Stop trying to cloud the discussion with facts!

I know some people are negative on this board. All I can say is that I've learned a ton.

I'm toying with asking a really dumb question. Not eager to take a ton of flak.

I've been using a Fat Wrench for years for mounting scopes and rails, no complaints.

Put your fat wrench on a calibrator some day and see what it actually does.

Well, I can agree that the "scale" on the FAT wrench is like trying to use the parallax knob on your scope to estimate distance...

Any measurement is a form of language. If that language is tied to a reference it can be duplicated by someone else. If not, it's use is important only to the person that owns the measuring device. Stated differently, if a torque measuring device is "off" it is still generally usable for the owner because it provides an arbitrary reference point. That said, it is more useful if it provides a recognized reference point.

Are you afraid to ask what I meant by use of the tool will result in a bigger error?

Go look up a user manual on any quality torque wrench, then read the part about how you apply force to the wrench in a steady even movement. No bouncing or jerking on the wrench. as this will cause the tool to under torque your fastener.

Then there is the subject of the torque spec itself. How many specs are written for firearms that specify dry or lubed torque? I can tell you i've never seen a recommended torque spec from a firearm or firearm accessory maker that specified a dry or lubed spec. Granted on a 1/4-20 or 8-40 fastener or smaller it's not going to be much of a difference. that 10% accuracy might just be what lubed and dry is on a small fastener.

Thing is it don't really matter. If your scope or ring maker has a spec, follow it. It may save you a warranty argument.

No, I did some chrono measurements and there were issues. Most likely my bad because everything shot quite well. I do my hail Mary's in a different post. I believe I did not correctly set up the Labradar. The speed was unexpected.

Incorrect terms. a "reference' is not a noun. It's a verb. You reference a "Standard". If your torque wrench can not be reference to a standard then it is "out of calibration" and it can still be used in a "for reference only" setting. If you want to pick it appart further a torque wrench will apply a given pound inch,foot or Newton/meter to a fastener or other device within a given degree of uncertainty. Thats that 10% we were talking about.

the thing is we are talking about wrenches the hold a base on an action, a ring on base, and a scope in a ring. if we are closer then 10% is it going to matter? Vortex states on some of their scope no more than 18 pound/inches so are we really concerned with +/- .9 pound inches??

I've got enough familiarity with Lab radar to know I don't want to own one. They can be fickle creatures.
