Just curious... Has anyone used the craftsman torque meters? Looks like they are just a strain gauge hooked up to an electronics box to give the angular force applied.

Sears Craftsman 1/2 in. Electronic Torque Meter
http://www.webbikeworld.com/r2/torque/torque.htm
Take a look at the link, I saw it the other day and it still looks clumsy. I will stick with my CLICK torque wrench for now. As the guy review the Electronic Torque Meter, it is not so handy tool. |

So, I bought one of the craftsman electronic torque gauges off of Ebay for about $50. The cable is annoying at times but less so than working on a chevy at any given time. My favorite feature is the audible beeping that gets closer and closer to a tone when you reach the correct torque. I think I'm gonna keep this one and my 1/2" clicker too.

I did not buy or try it.... just saw it on the website.... your report of its feel does not surprise me... some things are safe to buy cheap on sale...and others are ' IFFY'... we will put that one into that category...
I still have my 30 year old spring bar types... so you know I am cheap... We ought to fix a really simple but accurate device to test torque wrenches and post a picture .... all it would need is a nut on the end of a tube to fit any socket one has for their Twrench ( so one would need two in order to check both lb feet and inch lb ranges )... a way to mount it horizontally and a way to hang weights at various distances from that nut... While crude in look... this same method can be used with Great accuracy when balancing the weight of things like pistons... I have seen 10 ft EM tubing used for this sort of thing...very accurate when applied correctly. |

Something very similar to the sliding weights on a cantilever scale sounds like what you have in mind.
Yes, there are some things you can get by with at cheaper Harbor Freight, but many items need to be checked out very thoroughly. If someone is very familiar with the quality details to look for, they can chance on to a good buy. Stay away from ary of their ratchets. Terrible quality. Northern Tools has better quality and you will pay a little more. A little more bang for the buck. They also sell S&K brand on their website which is professional quality. Their Titan brand (even though it is made in Taiwan) is the best of both worlds. I would recommend Titan for torque wrenches and ratchets, which are excellent quality for the money.

"Stay away from ary of their ratchets. Terrible quality."
Unfortunatly this has applied to my experience with Sears Craftsman ratchets... for many years.... which really pains me because I love the rest of their hand tools... ( but in general avoid Sears items which have motors attached ). Yesterday I got one of the 1 inch ( ONE INCH !!!! ) drive impact wrenches...from Harbor Freight for $124 ...half what they claim is regular price..... just could not resist trying it.. since I am about to split my old 340 Farmall Tractor... I can barely pick the thing up.. but it says 1400 lbs of torque if you give it enough air...if they cut any corners on manufacturing or designing it it was on the inside.. because it is beautiful on the outside. |

Ahh, there is nothing like banging away with an inch impact. Takes a ton (I mean a ton) of air to keep it fed, though. Big compressor, big feed hose. I don't know about the newer styles, but Dad's older Chicago Pneumatic requires a line oiler (unlike smaller impacts where you can get away with dribbling a drop or two in the inlet every once in a while).
I just helped Dad put a new rear case (and newer gears and new bearings) in one of his Farmall M's this last winter. The summer before it broke a tooth off a gear which then proceeded to go between the gear and the case. I guess it made a heck of a bang when it cracked.

Checking a torque wrench can be as simple as applying vertical force on the wrench while standing on an accurate bathroom scale. Checking both ways accounts for hysteresis. You don't need a fancy torque meter. If you want accuracy, check your bathroom scale against the one at your doctor's office. I know my bathroom scale is shot, because the weight it reads keeps going up.

I have an inline oiler and will move it to this tool...
I am way underpowered on air at this time....( for this operation ) I am thinking I will need to mount my 60 gallon upright on a trailer and run it off the pto of the 5600 Ford diesel ..... which also lets me do it anywhere on the farm that has level ground ... Hum... that makes me wonder if I need to get a bigger oiler so as to not have a bottleneck in airsupply.... I doubt my old regular one has 3/8ths holes.... |

Not sure what size Dad's oiler is. Older than the hills, I think, but still seems to work. He still uses one of his 1/2" CP impacts that he bought when he opened his shop in 62.

I don't think these Harbor Freight wrenchs last that long. I have a Powerbuilt ½ drive Digital Torque Adapter that I use to test the accuracy of my torque wrenches from time to time. Here is a video of it. Powerbuilt Digital Torque Adapter - YouTube I put my buddy's 1/2 drive Harbor Freight torque wrench that's only been used a few dozen times on the Digital Torque Adapter. I found at the setting of 50 ft-lbs, the torque adapter noted 53.4 for an error of 6.8% . At the setting of 80 ft-lbs the torque adapter noted 71.3 ft-lbs for an error of -10.88%. Needless to say, that wrench went to the garbage. For twenty bucks or so, you get what you pay in that case. I prefer CDI manufactured wrenches, which includes Snap-On. Well worth spending the money on a quality tool. .
