Is this adjustable?

[JohnD]

I love to browse online auctions, and one came up with some small-force torque wrenches.   I bid, and won!

It was 'only' £12, although P&P was another £10 (!)  and when I got it, I realised, this is a VERY small-force torque wrench, up to 35 pound-force INCHES, 4Nm or 3 lbs-ft.   The whole device is 10" long!  Any watchmakers like to buy it?

But it's a nice piece of kit; unless someone else really wants it, it's a keeper.   Tested on the bench it slightly overreads, like 2 lbf-ins.     There's a large screw, right through the body, visible above at 11 o'clock from the dial.    is that the screw that compresses the spring that applies the torque?   Would adjusting that recalibrate it?

PS I also bid recently for a large ultrasound cleaning bath.  It was large, the tank was about a  two feet cubed!  Just the thing for engine parts etc   I bid £60, would have gone to £100.   It sold for £480!   Que sera!

I have a cycling mate and he has some carbon fittings that need lesser torque settings than I could provide him with , with my normal car focussed torque wrenches. 
 

perhaps you could re market it ?

Yes, you can get little 1/4” drive torque wrenches for bikes with very low range settings. They cost a lot more than £12

You win some, you lose some.  This times a winner!

This IS a low torque wrench, 5-40 ft-lbs.   Bought from an online auction, for less than £20, it was made by Norbar, a good name I think.  I've tested it by my usual method, clamp in vice, hang heavy weight off the handle, and it reads slightly under, which is better than the other way!

From the same sale, I scored a 'lazy tongs' pop-riviter.  For long, I've found that the hand-grip style of tool is fine for 3mm rivets, but anything bigger is a real strain.   This type let's you use body-weight and/trunk muscles to compress the rivet.   Again less than £20 when its new at £75.

But there were other bidders, and I was outbid by more than I wanted to spend on one lot, so bid on another.   The overbidder must have dropped out, as I also won another lazy tongs!

This is unboxed, not new, but not worn, and I want rid of it!   What am I bid?

Like the Norbar wrench. That’s a good catch.

What size chuck(s) John? Do you know if these are still available?

[JohnD]

It's a half inch square drive.    Might be considered a bit over engineered for low torque wrench, but probably a greater range of sockets available for this size than anything smaller.

Norbar still in business, with products looking very similar, but nothing exactly the same:. https://www.norbar.com/products/view/nsubcategory/categoryname/torque-wrenches/category_multid/1

John

sorry I copied your whole post rather than just the lazy tongs if those are surplus to requirements

[JohnD]

I'm not at home now, Colin, but en route to France.  From memory, for 3, 4 and 5mm rivets, but I'll check and let know when I get back from CLM.

[Escadrille Ecosse]

No worries John. 

Enjoy yourself

My Dad bought me a Norbar torque wrench when I was 17, that was forty odd years ago, quality tool.
