Torque for front trigger screw

Have a query is there a set inch/Lb for the front trigger guard screw on the No.4's and Mk III's as I have read that it can affect the accuracy of the rifle if I.E too tight or too loose. TIA

Ist click of the elbow.

TIGHT

Thanks guys I put 50 inch pounds on it our range guns (Barnards) are 55-60 inch pounds so I erred with caution as I am apt to gorilla things (As Peter has alluded some do) and as it is my T I thought caution so is 50 inch/lbs enough or go to 60! I appreciate the replies
Hey Muffet is that when the wife creeps up behind you and scares the begeezers out of you as you concentrate on getting the rifle back together, that was my white hair moment today I am now plotting my revenge...........:madsmile:

Is not the important thing to feel the torque required rapidly go through the roof as the wood is nipped up and the collar is suddenly holding everything apart? The precise torque required to compress the wood may vary a bit due to different wood, damaged threads, etc, but you can sure feel the sudden change to steel on steel at which point I stop. I find that, occasionally, I can tell if a collar is too long or short by the feel.

Ridolpho

If the manufacturers had wanted you to tighten the beejeesus out of it, they would not have used screwdriver slots,
or placed a metal collar there to lock down too.

Personally I do not use a torque wrench on my rifles. For me, it's easy to feel when it's tightened just right. But I've been a mechanic for over 35 years so it's sort lf second nature.
I'm just hoping anyone who's using a torque wrench does not mix up the "pounds/ inches" and "pounds/feet" ! That could be troublesome.

Some of the younger power tool hungry colleagues at work are good a snapping bolts! but have no clue how to get the bits out when they've broke it:banghead: But it means I won't be out of a job any time soon!

30three,

Yes, having 'feel' is maybe dying out a bit! Some folks seem a bit numb... Certainly not talking about you, Cinders me old mate!
You can feel when something is tight enough. but never thought how to explain what this means!

Thanks for the replies chaps I took the T to the range yesterday as I had done some very judicious polishing of the sear and trigger (Small dremel polish wheel) it is smooth as now with good feel on the 1st take up and smooth crisp release very happy with that as far as the front trigger guard screw goes the rifle grouped very well I am having a bit of a hiatus with trigger release at present and my groups have opened up so I am trying to get that together before this Saturday.
So I left it at 50 inch pounds and concentrate on seeing how much better I can get with A) Trigger control, B) Bit more load development with these new 174gn Bullet Factory pills as I have made them the same as my SMK loads I just feel I can get them to really perform because they are very well finished off the meplats are crisp and flat very nice.

30Three you talk of young'ens had a crane driver (Lever Attendant) changing the front left steerer on a 25 tonne P&H crane it was a UD carrier (Nissan) he was squawking badly about tight wheel nuts so I wandered over to assist with the change as he had a mighty big cheater bar going on. He had snapped 2 wheel studs and was really going the biscuit on the dead heads that had done them up so bl**dy tightly till I quietly pointed out to him that A) he was on the left had side of the carrier and B) That the studs had a rather large "L" stamped on them...........I left him to it but my boss was none to happy with what had happened as we had no spares and the crane could not be driven on the road with 2 broken studs safety issue. On a site yep, on the road nope.

Lastly the 50 tonner I operated for some years a Tadano 500 E-3 had 120 wheel nuts 40 on the 2 axles up front and 80 for the rear 2 axles being an inner and outer nut type arrangement, it is awesome fun changing a flat rear tyre which I do not know why was always the inner with the temp being a moderate 48 degrees celcius in the water bag. I was nearly a piece of melted wax! :eek:

The old left hand thread! many years ago a colleague fitted the driveshaft and hubs on the wrong sides of a pre war Bentley. Put the wheels on and tightened the central spinner (large single winged nut) with the hide mallet; not realising he was the wrong way round. The test driver lost a wheel entering the village. Had to retrieve the wheel from someones front garden and explain to the boss why it fell off!

I still have "sputnik type wheel brace that is bent, from a big heavy bloke borrowing it to change a wheel, and yep, was reefing on it in the wrong direction!...

Let's put this to bed once and for all chaps............ If the front TG screw comes loose when you've been using it, it wasn't tight enough. So do it up TIGHT!

Can I just add that torque wrenches are for modern weapons in synthetic stocks, (my US M24 SWS came with one), and not Lee Enfields. As Peter said, just do it up hand tight.

I save mine for alloy engines!
