Thanks for the reply, Larry.
I really like the 1x4 Technic roundend with pass-through holes.

In this oval window construction, the inner wall of the white 1x4 arches
hold the two vertical-oriented black 2x2 tiles very snugly. So snugly that
any looseness due to the Technic pins is mostly taken out--I dare say
completely eliminated. In a similar way, the inner arch walls would prevent
rotation if one were to use the brick hinge.
I continue to be absolutely amazed at how well LEGO(R) elements fit together
in all sorts or orientations. They are ingeniously engineered around a very
fundamental unit of brick! In this case I have learned how unique is the
thickness of the 1x4 arch wall and the air-gap between the walls.
Steve Barile contacting me about the oval window with the following suggestion:
Steve suggested using the 2x2 round-top brick with two 1/2-studd offset
knobs on the top. He reckoned that this round-top brick would be a good
match to the 1x4 arch brick. It sure is!
He is a construction solution to make the oval window using the same 1x4
arches and two black 2x2 round-top bricks:

Note that this solution allows for a lower profile oval: Reduced oval
height by 2 plates.
I am eager to see a solution that attaches the top-most white 1x4 arch element
more securely!
later,
James Mathis
