Well, it was a long shot anyway. Once you threw the gauntlet down the likelihood of changing your mind rapidly approached zero.

To paraphrase Galileo: "Nevertheless, it is an offset joint!"

Kurt, those are boiler seams and they show the plate edges "offset"
or overlapping -- i.e. lap seams. I think the illustration you are
referring to shows THREE plates, of which the one with a bend in it
is a reinforcement plate.

Nice try, but no ceegar.

Tim

If someone can find a published prototype name for this type of seam,
I'll use it.

Railway and Locomotive Engineering, pg 363: "Fig 12 is a double rivetted seam of . . . with an offset strip of 3/8 strip on the inside . . ."

The figure shows a strip with an offset formed into it. The joint is an offset joint.
