Now just to get the thickness right. If I go to a hardware store and find some that'll be easier. If I go through the internet might get a little tricky.
You really want phosphor bronze or beryllium copper .015”-.020” (.4-.5mm). Brass is not spring temper, phosphor bronze is. Easily found on the bay.
