Torque setting for tikka T3 action screws.

[Mungo]

lb-ft or lb-inches. OR Newton-Metres

Ah!

I see the logic in that.

Thank you

Anyway - I set the torque driver to 35 oojuns and go from there.

 

[Mungo]

I think you mean 35 in.lb

The T3 has steel inserts in the bottom plastic which make it pretty tough.

Like I said 35 thingummies.

Energy = 1/2 x mass x velocity²

Units?

 

[Mungo]

Units?

Oojun in imperial, thingummy in metric…

 

[csl]

Units?

I was just having a snigger at people who get torque (distance x force e.g. N.m, lb.ft) confused with the almost obsolete usage (except for firearms etc.) foot pound (ft.lb) of energy... sorry, you may continue

Having never had a clue about any of this (as is clearly apparent), I went to do some Wikipedia reading. It turns out that N.m can be used for both torque and energy. It’s just possible that my confusion around ft.lb and lb.ft stems from dimly remembered gcse physics where N.m was used for both.

Anyway - good to learn the right terms.

I once heard someone tell his thicko brother to tighten a scaffold clip "As tight as you can, plus one full turn".

Units?

Joules

Ha, so if I set my torque screw driver to 35 what’s its and then check that the oojun is set in a corresponding angle during a full moon, then that is correct? Does that take into account that I am using open sights?

Only on a leap year

 

[courser]

Will this also apply to rifles firing copper bullets? As you know, copper is affected when the moon is at its full and if the action screws are magnetised being steel and not aluminium, would this affect accuracy?.

5 nm.

In Germany the standard torque value is “gutentight”
I reckon you’ll not go far wrong !

First class! But is 62in-lbs too much? In my ignorance I would have thought 35in-lbs to be nearer the mark. I don’t understand
Nm. Although I have been a bit joking in my post, the original question was serious.

62in-lb for metal trigger guard..
T3 models are plastic.
I was more taken back at 80in- lb
for base to dovetail !

NM metric where inch- lb imperial
a bit like metre vs yards old school

Hope this helps ..

Ft/lbs is not a measurement of torque it's the amount of energy needed to lift a 1lb weight 1 foot, torque is usually measured in newton/metres, lb/ft or lb/in

All wrong mate. Neither of the above are ratios as implied here. They are products: Force x Distance, Newton x metre = Nm and so on.
