That was immensely helpful! Thanks a bunch! (Nice camera and lighting work! It was concise and thorough too. Great!) I just wish I had bought that exact crimper instead of the Engineer PA-09. The quality of the Engineer crimpers seems very good, but it seems to only do one set of legs at a time and also the largest opening on the PA-09 is 1.9mm, the Duet site says you should use a 2.2mm jaw opening. Oh well, it does seem to work... For all I know, 1.9mm is perfect.
