This wrench states 10-100ftlb. Is it true that if I am torquing something at say 96 ft lb it would not be accurate or not "click" at all. I have read, that though the wrench states 10-100, its useable range is like 20-90.

Really? I've been at this game a long time and that's one I've never heard. In fact, I've set torque wrenches at their absolute max....which is usually a tad beyond the marked max and they've worked everytime.....course I don't recommend doin it. All the ones I've ever used will go at least to their marked max. Never heard this one before at all.

Like I said before, most people out there don't use a torque wrench in the most correct way, if they use one at all.

Aircraft Maintenance 101 dictates how to use a torque wrench. I, along with every other crew chief is taught to max it out, click it like stated, run it down to lowest setting, run it back to max, click it again and do this 6 times. Also been briefed that the bottom and top 10% of the torque range is not useable/reliable on a given torque wrench.
I figure if that's they way we're supposed to ensure proper torque on a $2M motor in a $30M aircraft, I'll use that practice on a Jeep

Coupla ways. Ideal is to have a junk impact socket welded to a plate of steel that is bolted to a workbench or something. Its gotta be something that won't grenade when you start cranking 200ft lbs of torque. Another method, if one is so inclined, is grip the penis part of the torque wrench in a vice and break torque.
And yep, a stationary bolt works too.
