Thanks guys.  Maybe my explanation wasn't spot on but the claw foot wrench is what I need, but the claw has to be longer.

In reply to Curtis :

Ok I made a mistake when I type this.     Should say multiplies the reading .

Extending lever length. Below shows an attachment that adds to the lever length with the applicable formula for obtaining the correct torque reading. The formula is as follows:

For example, if the length of the torque wrench is 10 inches, the length of the attachment is 4 inches, and

the desired torque to be applied is 300 inch-pounds, the formula would be completed as follows:

Realize the above post is long, especially with the diagrams included. Sorry but it explains the process. This is copy/pasted from Army Aviation General Maintenance Manual and is duplicated in my A&P Handbook. Have the General Maintenance Manual in digits so I could copy/paste from it. Would have had to scan the A&P Handbook.

Which is why I stated in my first post to use a 90 degree offset. No math involved using the above formula. If A =0 then both L's cancel out leaving TW=TA.

Thanks, very easily understood (love pictures!).  With that and the previous posts, it appears that if the claw foot is 90 degrees from the torque wrench, then there's no math.  Direct reading.

With that in mind, I welded an open end wrench to a 1/2" drive socket.  Will put it 90* out and tweak away.

Hey, extra points for the banner?
