scope torque

[Hayfoot]

As a side note, according to the link those rings weigh .4 POUNDS (almost 1/2 pound) which is a rather heavy addition when added to the weight of a scope!

Yeah... this is my learning curve... didn't really notice that when I saw "oh look... they're on sale". haha... ugh.

Something to keep in mind with older units (not sure if still applies) is ....taking a torque wrench only to within its 10-15% min-max settings. Numerous reports of faulty reads/clicks within those ranges. So I'd get one that gives you "wiggle" room and not at its max.

The scope rings mentioned are the Night Force X-treme Duty rings.  Very expensive!
The screws that hold the dovetail are made from titanium!  Everything that was said before is fine for steel.
Titanium is very different.  It will stretch.  Perhaps that is why they recommend a torque # that is almost twice what is used for steel.
My recommendation is sell the Nightforce rings and buy a cheap set with steel screws.  Since it is on a PCP, you do not need much to hold the scope in place.

Thanks Yogi... wow, so much to keep in mind.
Here's the laugh... "that's what the salesman recommended".
How does using those titanium rings effect the scope rail? I see they're overkill, but is there any damage to the scope mount?
lesson: ask questions here before buying 'anything'. haha

note to self: stell rings weigh WAY too much... titanium rings COST way too much.

Maybe a stupid question here, but do any of you lubricate the screws? I use either the included allen wrenches that come with the scope (anybody wanna buy some?) or a multi allen wrench set from Lowes or HD. Especially on the top straps, I get this liitle "iirk" sound when tightening. I'm thinking it's from the paint-to-paint contact, hence my question about lubrication. Am I over doing it?

Also wondering if anyone has thoughts on this product



It's in Nm, I know, so a bit of conversion is necessary.
They're $49 at Creedmore.

12 newton meter is only 9pound feet.  At least according to my conversion table.

That is not enough to tighten most airgun screws.

Thanks Yogi. I probably should have researched that myself. Gehmann makes primarily competition sights, and the fact that the accessory bits are only 2.5 to 5mm should have been an indicator as well.

12 newton meters equals 106.2 inch pounds (not foot pounds) which is well over double any airgun torque rating I've read.........

And so, using the Gehmann tool on the low end of it's range (4Nm) and using the above calculator, yields 35 in/lbs, which is the rating used for the horizontal screws on that Leapers package. There apparently is no way to get 15 in/lbs from that tool. What the heck are these guys tightening with it?

Is there something I'm missing here?
