Brass that isn't brass
Original poster: "Pete Komen by way of Terry Fritz <twftesla-at-uswest-dot-net>" <pkomen-at-zianet-dot-com>
I discovered that the "brass" knobs that I used in my spark gap are brass
coated zinc(?). Under the yellow colored brass skin is a silvery
I just got some 1/4 inch "brass" acorn nuts. Imagine my surprise when I
discovered that these "brass" nuts are magnetic.
I thought that acorn nuts would be solid brass, but no. Same for the knobs,
but I guess "brass" means the finish and nothing else.
I hate not trusting these stores (the store may be a victim) but I think
I'll subject "brass" to the magnet test and the file test before I buy more
than one of any item.
