Hi Randall,
I agree. Sometimes HF is good stuff and sometimes not.
My last engine rebuild was in 1971, so I haven't used a torque wrench in
a long time. The one I used then was a bending beam with pointer and
scale kind of thing.
I had assumed I should buy a pricey up-scale instrument kind of thing
until I saw the torque specifications in my TR250 Bentley. The ranges
are very broad: 26-34 is a typical number. My thinking is a difference
of 8 in this example so, 30 is in the middle +/- 4. 4/30 is about +/-
13%. I would set the torque wrench for 30 in this case.
These HF torque wrenches claim to be +/- 4% so I figured they were OK --
three times more accurate than I needed (in the typical case).
I understand your reply to doubt whether these HF wrenches are what they
claim to be -- accurate to +/- 4 %.
You also seem to not like the clicker style. I thought it would be good
because using it would not require me to be read/view the scale.
What would you suggest that would get me a typical +/- 13% or so.
Also, how do I recalibrate a clicker type?
Thanks for the response,
Don Malling
