I have been away for a few days and just found this discussion this morning. Before answering I took another picture of the stitching. Yes, They are home sown. Data used for the stitch pattern was obtained from ON ROPE North American Vertical Rope Techniques New Revised Addition By Bruce Smith and Allen Padgett Page 239 and following. They are sown with #138 20 lb nylon thread. approximately 240 stitches in the pattern. Since I have experience in mechanical engineering, several years ago I built a hydraulic test pull device and used it to test some slings. I found that like the data published in ON ROPE my slings would usually break in the web before the stitching. I use an old singer commercial sewing machine. below is a close up of one of the slings.
I have confidence in climbing with these slings. I have used them for both recreation and for work as a millwright building grain elevator systems. Many times in commercial work the slings we need are not available unless custom made. Flame away. and for your safety don't climb on any piece of equipment you don't trust. If you were climbing with me and wanted to use your protection instead of mine you wouldn't hurt my feelings... it is YOUR life at stake. climb safe.
