Hi,

I'm shopping for a quality, calibrated or calibratable torque wrench. I'm finding a price range from $200 (Aircraft Spruce) to $375 (Snap-On, 2% accuracy electronic). Stanley makes a really nice set of the "CX" series with a 3% accuracy. But I have no strong opinions. In the past, I just bought auto-grade torque wrenches and hoped for the best. Right now, I'm thinking 3/8" drive, 40-200 in-lbs Any recommendations from personal experience either angels or goats?

I have tapped, aluminum blocks to deal with along with the usual 4130 tubes attached via AN hardware. Now I like a ratchet wrench as much as the next guy but am I being a little paranoid about whether they can accurately measure the torque? I like the "memory" dial gauges but the electronic ones can be used "blind" and remember the max torque.

Also, does a torque screw driver make sense? I want to buy a quality tool but this is not going to be my livelyhood (although it might be important for my life.) Thoughts? Suggestions?

Thanks, Bob Wilson
