Torque Wrench and calibration
I've gone thru over a dozen torque wrenches in 15 years, from craftsman to snap-on. For the last 10yrs, I had calibration equipment readily available to me. IMO, the best 1/2in drive for the money is available at Home Depot for 60bucks, Husky brand. It's calibration lasted the longest of all the ones I owned. I go thru them about 2 per year, but I torque at least one set of wheels a day, and abuse the Husky regularly. The best 3/8 drive I still use is a beam-scale type, but also have a pretty accurate craftsman 3/8 click type for cam caps etc.
I'm also a believer that a lot of reused fasteners and non chased thread holes make torque a suggestion. IMO, the biggest use for a torque wrench is wheel bolts/nuts, where the absolute value isn't as key as is the equal torque of them.
I wouldn't spend a lot of torque wrench money in the snap-on truck, unless you rarely use it, and like the name. For a daily driver, the Husky gets my vote. I give a lot of them away to customers (including my old ones), since wheel torque is one of the most overlooked safety items on any vehicle.

I asked the Snap-On dude today how much for a calibration and he said that depending on the size it ranges from 40-150 bucks + 15.00 shipping. They are all flat rate services that include breakdown, cleaning, inspection and replacement of worn/broken parts, lubrication, assembly and calibration. I don't know if they are calibrated to a traceable NIST standard or not, I forgot to ask that.
THat seems a little high. I work for a Calibration lab in Boise (Boise Calibration Services) & it's $35 a wrench, another ~$40 if it is bad & gets sent off to California for a rebuild.
Buying your own standards to cal' torque can get pricey, but with a little inginuity, one could build their own torque tester.
Yeah, it seemed high to me too. I think 35 is what my company pays.

Maybe I'm thinking too crude...
Couldn't you connect the wrench to a socket welded onto something that won't move then hang weights off of it at a specified distance until it clicks? The amount of weight at a specific distance out = torque right? As long as you load the weight on in small increments you would be able to tell at what weight it didn't, then at what weight it did click.
yep,
need to take into account the weight of the wrench though. I was thinking something along the same lines the other day in a thread further down the page.
