[QUOTE="doug, post: 340827, member: 1835"] When you're casting Hi-gold alloys you can get away with less tension on the casting spring. The ring is filled before the arm moves a 1/4 of the first spin. If you have it wound too tight the metal will splash around in the mould and cause problems with the density of the casting. Also, I tell you this from experience, if you over wind the casting arm you can shoot that molten metal right out of the top of the ring. That's a party. [/QUOTE]
