Torquing the AN3 Aileron Bracket Bolts help

Torqueing the AN3 aileron bracket bolts help

Researching torque wrenches and I have come across an issue. I'm looking in the in-lb range of 20 min. to say 150 in-lb. The problem is the torque wrenches that have the lower range are typically 1/4 in drive, which is ok, but will I need a set of crowfeet (crowfoots?) to torque the bracket bolts/nuts?

Just the initial install I could not get a socket on the bolt or nut. Therefore I'm thinking a open end wrench on the bolts and a crowfoot/torque wrench on the nut. A quick search of tool suppliers shows the 1/4 drive crowfeet are scarce and expensive. Where 3/8 drive are common and less expensive.

Interested in what others have done and other options.

Adapter

I have a 1/4f to 3/8m socket adapter. Mine is a Snap On but I'm sure Sears or one of the big box stores would have one for you.

Buy a 1/4 female to 3/8 male adapter. Works for me.

I just used a set of regular wrenches with my highly calibrated fingers. Get it tight, but not overly tightened.

D'oh

Ha, well why didn't I think of that (adapter)! How do you delete a thread?

If you do not have calibrated fingers get a fish scale, use it to pull on the wrench.

Could you elaborate? I'm going to guess a lb. on the scale is 12 in./lbs.

Only if the wrench is 12 inches long...

Seriously, the torque is the distance between the center of the bolt head to the point where you are pulling on it (for example, 5") times the force (for example, 4 lbs). In this case 20 in lbs. Pull perpendicular to the wrench.
