Outcast raises a valid point But repetitive load cycling examines creep . KBS examines UTS and you are correct in your concern where the creep testing load exceeds the elastic deformation range of the mono. The question becomes at what load should creep testing be undertaken. In my case I adopt a protocol of 150% of intended max drag, which is well within the elastic deformation range. KBS testing is undertaken in a single incremental ascending load cycle on a previously untested sample. ie the two tests are independent. Re Braid ratcheting crimpers: Yes, very reproducable crimping pressure, but tuning is limited to line size choice & crimp choice, without engineering modification. ( we have already discussed the impact of line size within crimp range, so the potential issues are clear and the limitations on optimisation obvious). Re Jinkai SC-3 crimpers ( & other products similarly adjustable ) Within a line size & crimp choice they are adjustable for optimal results, but once that is set it is optimal for that setup & that die hole alone. Not necessarily optimal with another line size, crimp & other die hole. sure, you can adjust the tool to suit another combination, but any concept of doing that on the fly is an exercise in futility without testing the adjustment again. If you want reliable crimping with these types of tools you need to set them up for a single line & crimp combination, lock the adjustment down & use it for that combination. If you use a range of leader sizes , for reliability at optimum join strength, you should buy another SC-3 or similar & set it up for that Job............a one time investment of $30 or so for the specific job you intend to use it for. Which type of tool is desirable depends entirely on whether your choice of line has a compatible crimp for optimal KBS in the fixed OEM setup of the Braid ratcheting crimper. The Jinkai SC-# is more user-friendly in adjustment.........as is another similar Braid hand crimper. The test series will be very useful in identifying those combinations of line size & crimp brand which produce optimal results in the Braid ratcheting crimper & those which are probably optimised in a different tool. What we can expect to see is that the Braid ratcheting crimper will perform below par on line sizes at the low end of the line size spec per crimp size, where a thicker wall crimp cannot be matched to it...........IMHO. My thoughts on the test series remains as prev stated. It needs to focus on a particular leader size & brand & see what combinations achieve optimal KBS i) by swapping crimp brands in John's crimper. ii) by using a pressure adjustable tool & seeing whether further improvement can be achieved.
