This is revealing about masonic rods...
"In Minnesota, Deacons and Stewards are directed to carry
their rods at an angle of 23.5 degrees from vertical, imitating the
tilt of the earth's axis from the plane of its orbit."

So, as I assumed, rods in masonry have a connection to gravity and geography, as the plumb bob/line does. The rods tilt as the love birds do, according to true gravity, as opposed to other forces- such as those created by a swerving car, a symbol of Tippi's overwhelming desire and impetuousness- traits unwanted by the mason.
"Hunter, however, notes three main ways the film differs from his screenplay:
An addition is the scene where Mitch and Melanie leave the children's birthday party and go up into the dunes and discuss Melanie's empty life and her lack of "a mother's love." Hunter recalls:"
rodtaylorsite.com/birds.shtml
So, Hitchcock inserts a scene that specifically criticises Melanie(Tippi Hedron), who is hated by the birds. That's the point. the plumb bob found her wanting. And as long as Rod and Tippi are together, the birds will attack us. Is this a kind of explanation of why animals fear us? attack us? An inbalance in our own human nature?
PSYCHO seems to be full of hidden layers too. A pal of mine has been finding that Bates is the scarecrow from Oz and Marion is a bad Dorothy.
Dorothy contains the word ROD. O THY ROD. She is well mannered.
In David Lynch's MULHOLLAND DRIVE we see a blatant reworking of the plumb bob. And this one seems to be directly inspired by the mural in Pompeii.
Here's a close up of the bob over the skull.
Adam Kesher is in trouble. He refuses to hire a certain girl for his film. He has to go on the run. He is told to talk to the Cowboy. Adam finds the weird ranch where he is told to go, but no cowboy. A typical wooden ranch arch bears the plumb bob and the skull from the pompeiian mural. The light bulb is the bob. when it lights up the cowboy appears. If you've seen the film you'll already understand how connected to CORRECTNESS the cowboy is. He is deadly serious and intent on getting Adam to do the right thing, and hire the girl the spooky mobsters want in the film.
Look at his clothes. Pristine.
Read his words.

Plumb Bob sounds like a cowboy name.
But the comparisons continue. The mural has two sets of clothes, on eitherside of the skull bob. Tatty and new. Adam comes to the cowboy splattered in pink paint, ruffled, unwashed. The cowboy is pristine.
All the elements are there from the Pompeii mural. The wooden arch over the skull bob. The wheel fits with the cowboy ranch thing. The butterfly refects the bright clean colours of the cowboy's horrid jacket, and his neckerchief.
The dangling bulb bob.
Why is David Lynch so cagey about revealing the meanings of his films? or what inspires them?
Why is he slipping Masonic symbology into them?
Is he a good mason? then why not come out in the open? why choose a mural that depicts the plumb bob as DEATH?
ERASERHEAD by Lynch has a masonic scene too. A horrid one involving the suggestion of child sacrifice. Which is ultimatley the point of the film. A man being driven by entities from another dimension to kill his deformed baby.
Which he does.
And is gained access to those higher dimensions.
The rest of the film deals with dehumanisation.
