What do you torque your rails and rings at? do you use blue lock tight?

I feel that is quite abit.
Personally, I like 16 inch/pounds for the screws into the reciever and 16 inch/pounds for the rings as well.

Yes on the 15-16"-# for ring screws- No on the blue Loctite per some ring/base mfgs.
Loctite on DNZ, for instance, voids warranty. |

With Seekins rings, I use 15 in-lbs. for the ring screws and 43 for rings to base (which is the nearest to 45 that the Borka torque driver gets).

Reaction time is a factor...

I look up the max torque for that screw size.
Then I have to know what grade screw it is. Then I have to measure how much engagement with the female threads. Then I have to evaluate the female material; Steel is best, but it may be cast iron or Aluminum. If engagement is more than 1.5 times the root [minor diameter of the screw] the screw is probably the weak link. Then I have to evaluate the lubrication. Wax makes for much more tension from the same torque. Oil and grease not so much. Clean and dry is the least. Then I calibrate the torque wrench. I use as standards, a ruler and a weight that I weighed on a balance beam. Then I do a destructive test on sample material to verity my calculation is correct. If the female is the weak link, I mill sample material to the same thickness. So far I have only done all this work for the scope mount screws that I drilled and tapped into a Mosin Nagant receiver. But I have done parts of this exercise for many applications in gunsmithing. |
