I'm gonna answer all your post in this one reply.

My goodness you've been productively busy, and I thank you very much.

The contents/intent of your recent posts here will eventually make it into
the torque wrench page. I'm just not sure quite when.

 

The manual says you must dial it down to no more than 20% of capacity if
letting it sit for an extended length of time. This suggests that leaving
it at a higher setting will result in permanent distortion of the spring's
steel.

I'm paranoid enough to want to take /all/ the load off the spring when
storing the wrench, so I bring it down all the way.

 

Yeah, the detents should help hold the readings. The Sears version of
the Danaher-built wrench is probably the cheapest one they make
(especially during the 50% off sale), then come the Lowe's/SK and
GearWrench/Armstrong/Matco (3% accuracy). All from Danaher of course.

After reading Tegger's detailed description, I'm confident that if
needed you can order a handle from Sears (~$8 plus shipping) and
recalibrate it yourself (home-garage-grade calibration, of course). Or
better, change to a Lowe's or SK style handle except I'm not sure
where to get them (maybe Angle Repair?).

I would use a beam type to baseline the readings of your wrench at 30%
and 60% max torque (or more points), and measure the protrusion of the
adjusting bolt, similar to how you would a brake master cylinder push
rod. Adjust the bolt so you get minimal torque differences at those
points, well approximately anyway. It shouldn't be that difficult
(with the proper thin-walled socket and allen wrench) because one
adjusting bolt means linear adjustment, right?

Now, Tegger may be able to get that torn-apart wrench back into
service......

I wish! It's in the town dump somewhere by now. I tossed it during a
housecleaning soon after doing the intial writeup.

And hey, it's been a while, but I finally got your contributions up on the
torque wrench page.

Thanks very much.
