Missing .028???

[mhorowit]

I'm looking at my tubing catalog and see 3/4"(.750) having a wall thickness of .028 and an ID of .694. Now .694 + .028 = .722. I seem to have lost .028 somewhere!

Anyone have an insight? - Mike

I think they used that for the mystery spar doublers on the later spars that Mrs. Feris built with the 28xx drawings.

Never mind; I figured it out.
That's the kind of error I make that makes me scared to cut anything prior to measuring enough times to make myself ill. - Mike

You used the formula for moebius tubing...

That .028" was the missing dimension which allowed the government to prove the single bullet theory. I could explain it, but I'd have to kill you...

The diameter has two .028 wall thickness to add. Thus, the missing .028 is the other side of the tube.

That's why all of my tubing orders are placed through the Mythbusters.
