Report on sewn webbing joints

[Bob Thrun]

From time to time, the topic of sewing webbing comes up here. Experimental data on the subject are scarce. I came across a report done at the Royal Aircraft Establishment. Some Observations on the Behaviour of Superimposed and Lap Sewn Joints. This is a British report, but it is posted on the website of the Defense Technical Information Center, an American agency, and carries an accession number from the National Technical Information Service, another American agency. It is at http://www.dtic.mil/cgi-bin/GetTRDoc?AD ... tTRDoc.pdf

I have not digested the report yet.

It is a good thing that DTIC has the report. It is available from NTIS only as microfiche or hard copy for $27 or $33 because NTIS is required by law to be self-supporting. All or most of the government reports that NTIS has are public domain.

Thanks, Bob! I enjoy the sewing topic.

Let us know how that goes for you. It gave me indigestion. Though, I imagine it will show predictable results—more stitches equals stronger joints up to the point of the webbing breaking strength and stronger thread requires fewer stitches.
