Thanks for the articles. I realize they are articles, not technical papers. In my reading of it though, it was challenging to link the conclusions made to the data included. Unfortunately the link to the university page does not work anymore.I do like the threaded insert TP for experimenting.
Still, sometimes reviewing what others thought before us, perhaps even from a different perspective, is helpful in judging the merits of an idea.-Marty
It made me to think through what conclusions were supported and which ones were less so.
Rather than be put off by the TP articles, seeing them makes me want to see more (complete) research on the topic.
