TORQUE WRENCH FOR HIRE

Posted by: Onthlam on 10 October 2003

I have a wrench that will work on any of the Naim speakers that have 4mm alan screws.
I completed my torqueing about a month or so ago. Had very good results. I have passed it on to a fellow forum member who, I believe has also completed his mission..

If anyone would like to borrow it?
Please do not hesitate to ask.
It is set up for 3.6 and can be set up for a higher pressure if you so desire.Not necessary..

The only thing I ask is the last person to have it pays for the post to go to the next user.

Regards to all,

Marc

How often or when is this to be done?

I recently replaced my SBL mid-bass drivers. Should they need re-torquing after settling in after a few weeks or months?

What's the setting for SBLs?

Paul,
It appears that it should be done just after you set up the speakers for the first time. I expect to do it once a year here in California. I think if I were to live in an area that has more than 1 weather system, I would do it every 6 monthes..

The setting , I believe is the 3.6....
Your mid should have been torqued to 3.6 when first put in..I could agree waiting a few weeks for it to settle, then do it again....

Hope this helps,

Marc

I have relatively new SL2's. Where did you purchase your wrench?
Posted on: 10 October 2003 by Onthlam
Audiogoose,

I bought it at Sears....

Thanks.
Are all Naim Speakers torqued to the same setting?

Audiogoose:
I would suggest you send an email to Naim to get the Nums you need.
Just to be sure......

Marc:
Thanks. I'll do that.

Marc:

Thanks for the information.

Perhaps I should buy one myself. What make/brand is the wrench; how much do these wrenches cost; where do you buy them? I ask because I'm in Canada and I'm not sure if you want to start sending yours across the border.

cheers,

Paul

Paul,

Sears is the place. The wrench is the 25 inch pound minimum wrench.. I think that is right?
The wrench was 80.00 dollars....That included the 4mm bit...Not cheap, I know...

Ron??? What wrench do I have?

Regards

Marc,

I would'ent mind torquing up my DBLs if you would be willing to send it overseas. In the Radio Spares catalogue they want 80 pounds for the same wrench you have.

E-mail me if possible.

Yours,

Sean.

Sean,

I would like to do mine, also.

I would be happy to fund postage for the return leg across the Atlantic.

Sean,
I have no problem with that.
Let me get it back from Mr. Toolsie and I will send it out to you.
Sean: Will you send it to Martin?

Gents, my email is onthlam@rcsis.com
I will need address to you Sean...

Better yet, give me a mailing address and I'll drop ship it out there. I'm not at home at the moment, so I cannot give the exact details of the wrench, but it is set at the recommended Nm/ftlb. I have found that overtightening is almost as bad as undertightening.

Martin,

Recieved a note from Ron today saying that he is sending the torque wrench to me today. Mail from the States normally takes about two weeks, I'm offshore for three (I leave tomorrow, back on the 5th) so will send it to you when I get back. Drop me a line with your address and I'll do the needfull.

PS. I would like to take you up on your kind offer of the DBL profile for using on the CARA room analysis software.

Let me know when you get the wrench. I will take you through the subtle movements of the wrench...A "how to"...So there are no mistakes.

If you have had experience with such wrench-go to it!!

Marc,

With this wrench,no I have not had any experience. I do however use torque wrenches on a regular basis, although slightly larger.

Will give you a call before use.

Insure the 4mm bit is fully installed onto the wrench.
Take a look at the side of the wrench. It should read 3.60 where the black line meets the guage...This should also be locked in by twisting the locking sleeve.. Take a look-you will see what I mean...
Start on any one of the screws you want. just remember to go 10 to 4 or 2 to 7...Just like a clock..
Once you have the wrench ready to go, make sure your in the screw completely. First, turn the wrench to the left About a quarter turn. This will loosen the screw first. Next, go to the right and start turning the whole wrench very slowly..As you can see the wrench is a straight line. From the rachet end to the bottom of the handle it is as straight as a bat...
As you turn the wrench you will see and feel the wrench give way. STOP!! (The rachet end will be bent out of line from the rest of the wrench...Your there..) Because of the low torque setting you will not hear the click or snap you would hear at a higher setting.

Continue with the rest of the screws and enjoy the improvement......

This might seem a bit strange.. Once you get to do one..Your fine...

Just a bit of advice for anyone who's thinking of torqueing 4mm capscrews.

4mm is far too small to use a torque wrench to an relevant setting. It would be too easy to under or over tighten. Engineers never torque capscrews that small. It would be far more accurate to do this by hand and feel the capscrew tighten.

Also, the torque wrench would have to be made by a company like Snapon and calibrated every year.

Thanks for your thoughts..
However, a torque wrench is used at the factory and was used when set up for the first time in my home. Set up was done by NANA...


utilizing a good wrench is far mor accurate than feel.....(IMHO).......I want to meet the person who can turn screws to a specific measured point and do it multiple times...

Marc,

"The man who is afraid of asking is ashamed of learning" I would like to say this is a Chinese proverb, but it's Danish.

This is where you are totally wrong.

What is the specific measured point? Tightening a bolt correctly is to a point where the bolt stretches to a within certain length range to clamp two surfaces without deforming the material.
