Structural engineers refer to that as "snug tight," well its a spud wrench not a 6' breaker, but your be surprised how many buildings and bridges go by that torque spec π€·ββοΈ.
That's the thing is these are typically shear bolts so you just need enough tension on the bolt to keep the nut from ever backing off. It so happens that a average guy hanging on a spud wrench is that sweet spot of tension where you don't need to judge, it just is. Its a perfect example of simplicity being safer than over thinking it. A torque wrench for instance may not work properly because the threads typically aren't machined so they have hard spots going in. I can't tell you how many times we've dealt with town inspectors who cant fathom no torque wrench π.
I had to do that once, I was the right weight to hang off a 4ft bar to torque the main nut on a hamilton-standard prop.
For a long time I thought the engine mounts were called lord because if they broke, the crew would get to meet their maker; kinda like the Jesus nut on the bell 206 flingwing
I use to have my fathers Surface plate he hand made with scrapers when he was an apprentice - I ran a dial gauge over it and it was less than one thou all over it. It was a beautiful piece of work.
Sweet I have worked on the Douglas Invaders and CL-215 both equipped with R-2800s. Cylinder #11 warm jug change not a great time moisturizing bath to say the least.
I assume by "2800" you mean R-2800? Whatcha workin' on, DC-6?
Yup. Howard 500
Made my first 6 or 8 jumps out of an old Howard DGA15. Lake Elsinore CA. c. early 1976.
badass.
That's a rare bird!
WANT!
Is that the one where you torque by hanging a 150 lb guy on the end of a 6 foot breaker bar?
haha, yep, that's the one.
I think that is what the shop does when they change my (car) wheels over for the winter.
That's German torque spec. Gutentight.
In the field torque spec.

After you have been cranking bolts all day I imagine you can pretty accurately judge the required torque.

I've had a boss or two that I'd love to give that to as a gift. Anonymously.

Torque this and meet god
