HI all,
Just a word of caution when using the tester. Make sure the point of the hook goes between two threads.
I loaned mine to someone and he just stuck it in without care, nicked a thread and then was so heavy handed doing the test that thread broke and by the manufacturers recommendation that is considered a tear so a fail. We patched the butcher job and moved on to another location, this time I did the test and the fabric passed. so now he has this ugly patch he needs to keep an eye on for the life of his fabric. If you see a lovely white and red fabric aircraft with this postage stamp size pink patch you will all know who the butcher is/was.
I am on purpose not naming names or aircraft, this will drive him crazy, oh I am bad, he, he.
the other issue on a pull up to test stitching, please take care you are only testing the folded area with the stitches through it not the actual stitch material on its own.
Bob.
