Torque Wrenches for 1 Airplane Maintainer

All I have is an old bending beam torque wrench, any reason it shouldn't be used for prop bolts?

Im so used to seeing the dial and click type that get the annual calibration at work, it almost seems prehistoric.

I don't know how I'd manage the logistics of keeping a fancier one calibrated. Any better ideas and suggestions.

If it works for you, use it.

The Snap on guy that use to service my area had a calibration tool on his truck, he would calibrate my torque wrenches as needed.

Or find who does it for your company.

Re: Torque Wrenches for 1 Airplane Maintainer

I've used a bending bar torque wrench for placing dental implants for years. Old school but doesn't lose calibration, but it's a small one; 35Ncm

I would have it calibrated and use the hell out of it.

I use a Craftsman model 1019 Laboratory Edition Signature Series torque wrench. The kind used by Caltech high energy physicists. And NASA engineers. It has been calibrated by top members of the state AND federal Department of Weights and Measures... to be dead on balls accurate!

Re: Torque Wrenches for 1 Airplane Maintainer

We used both types when working on a lot of military and commercial type aircraft. As long as they aren't damaged they're as good as the click type, just not as easy to use.

I was not sure if that was the source, but Googling the first sentence confirmed it. Very funny.

Probably the best type of T/wrench made, if you know how to use it, I see no reason not to.

Re: Torque Wrenches for 1 Airplane Maintainer

Only a bending beam type wrench can hold a given torque for a while. This makes it better in certain applications, probably including wood prop installations.

Re: Torque Wrenches for 1 Airplane Maintainer

I have a click type but keep grabbing the bending beam instead...


They are cheap enough to have one in 3/8 and 1/2 drive

Re: Torque Wrenches for 1 Airplane Maintainer

1/2 drive I have a nice click but I just reclaimed my smaller 3/8 drive bending beam from my parent's house

Got a new car. 4wd 2004 Acura MDX w 200k Miles. All of the drain and fill bolts for the diffs, transmission, tcase etc... use 3/8 for the drain and fill bolts. Drain and fill bolts! I'm used to pulling transmission pans and diff covers, getting fluid on my head and scraping gaskets.
