'Wet' mounting scope rings

[John Weigel]

I hadn't heard about this previously, and find it very interesting. Putting it up here in case others may be interested. I guess the principal is that if there is inevitably a tiny bit of movement between mount and rail, its best to have the joint free to return to centre, rather than incremental creep due to sufficient friction that resists return to zero. Very cool. Also interesting to me Mr Spuhr's comments about lubing screws and value in rosin at ring to scope contact.

Sounds like "Specious Logic" or Pseudoscience. Notice there is no data to back up the claims. Reminds me of Eric Cortina's claim that CLR strips carbon deposit out of barrels. What he claimed was the carbon fouling coming out was , in a large part, the oxidisation of the stainless steel barrel. In other words, CLR was eating the barrel. Specious reasoning is a type of argument that appears to be true or logical, but is actually based on lies, misdirection, or misinterpreted information.

CLR indeed works as a carbon removing agent and is very effective in stainless barrels. I have been using it in numerous very accurate barrels and never sustained even a hint of damage. Yes I have borescopes. It is however damaging to carbon steel, especially blued parts. It strips and softens the carbon very effectively. It wont remove the hardest of deposits but it will make Iosso job super easy by softening carbon.

To say that CLR damages barrel to that extent that it appears as a fouling when pushed out of the barrel is just not correct. Run your own tests. I have.

It takes over 6 hours to even see any discoloration of stainless steel used in barrels. The idea is to use it for 5 min and flush out with windex therefore neutralising it, followed by whatever method of further cleaning needs to be done. It is not for everyone but it works great,

Winning in the Wind covered this and he basically said there will be a fine film of lube that will always be there allowing movement.
Dry installation and slowly torque the rings up and give very light taps with a soft face hammer to "settle/bed" the rings to the rail see video below

As an aircraft mechanic, tapping it as you torque it makes much more sense to me.
Hope this helps

Strange how many love to reference Youtube when the best bet for gaining technical advice on a product/install would be the manufacturer.
High end products almost always have high quality, detailed instructions.

If you had an action with integrated rail and a high end scope is installed to spec with a top quality one piece mount, like say a Hawkins, where is the movement?

As for Cortina, pretty uncool to post a video about how to find the lands
well over two years after the Mark Gordon(SAC) method was discussed and shown
by Cal at PRB in early 2020

Don't get me wrong, we love Youtube as it leads to lots of job requests to repair/replace after novice mechanics damage components.
Nm, inch-pound, foot-pound. All the same aren't they.......

You mean 20ft lbs for my scope rings isn’t enough??
Jokes please no one do that.
I think winning in the wind has the better way of doing it as well.

The interview is with Hasan Spuhr. He is the manufacturer of Spuhr mounts. I suspect you didn't actually look at the video. In the interview Hasan discusses, excitedly, the learning of something totally new in the narrow area of scope mount installation. Nobody even a little bit curious? Are the 'good old days' of development and experimentation in the hobby easily witnessed in the posts of 10 to 15 years ago (which I have totally ransacked) really over?

Sorry, I should have acknowledged that Geoff responded in a constructive manner. Thanks Geoff. BTW, I wonder why Keith tapped the scope laterally, and not frontwards/backwards?

That’s a good point John if anyone here has a mechanical engineering background that could explain further that would be great.

I seen area 419 and ultimate reloader talking “wet mounting” a couple of months ago but something I really agreed with in the video was torquing the rings to the scope before finish torquing rings to the base rail

G'day All,
I'd suggest that during torqueing all the load is in compression and it would allow the nut, washers? mount jaws etc to move and find there "Happy" place on the rail.
Also as Keith said there only needs to be light taps to ensure there is some movement to help alight all the bits n pieces.
During the recoil impulse and gap between the ring assembly and rail "faces" will take up and I would check the ring bolts for correct torque after several shooting sessions to see if it has changes.
Anyway that's just my thoughts and I'd welcome further input from those more knowledgeable than me....always learning something!
Cheerio Geoff
