Can anyone show point me to any handbook or spec that allows the use of swaging to repair slightly oversized helicoil threads?
The issue is that a supplier thought it was a good idea (after it was verified the NOGO side of the thread gage spun in 4 timesvs the limit of 3), to take a threaded form tap and swadge the threads slightly and then re-tap with the appropriate tool. Now the thread hole is "within spec" but in my experience this was not a conventional method of repair for this issue.
I am actually trying to give them an out, more or less, but I can't find it anywhere. They say their expert tool maker said this was a tried and true method but again, it seems like something I would do in my garage on my lawnmower block but not an expensive aluminum part.
Thanks for any help.
