He's saying there is some metal on the market from China masquerading as SS when it is not.
This should bring a Laugh :
In 2008 i had a buddy tell me, he had read on a forum about How to find
your SS T-nuts after you do the layup on the board, and it's time to drill them out.
?? what ??, you don't place a waxed hex-nut in them first, and have the top
a few thousands high so you hit them while sanding the bump off the top skin ?
"NO", he said , -- "they magnetize the SS T-nut with a wire coil & volts first, then
drop iron filings on the upper skin to find them afterward ...".
And the guy posting said: "the package indicated they "Were" SS" !
See where This is going ?
