Well, after my first try at making tie tacks and cuff links from spent shell casings, I got a special request from a couple of the Air Force Security Forces guys using the 7.62 rounds that they fire. Well, I didn't have any spent rounds of that caliber at the time so I told them if they got me the casings, plus a few more to make some extras, they'd get their bling. Wow...I'm not sure how "a few more" turned into a 2/3rds full ammo can of spent rounds but I have 7.62 casings in SPADES! lol I've also begun work on the tie tacks and cuff links and have the first pair of cufflinks finished. These were soldered in and I must confess it's the best pair I've ever made. I'm very happy with them and hope the tie-tack turns out equally nice.
