[QUOTE="ps2thtec, post: 97687, member: 3335"] Similar to your sprue I use a 8mm reservoir with 8ga feeder, but I dip the ball afew times to make it larger . I get a lot of FCC that weigh over 2.5dwt. Sprue to a thick cusp and I also use a small ga vent off the opposite cusp. Using Nat gas/ oxygen torch I set the ox pressure at 5lbs. And two winds. When casting a HN ceramic alloy I use 20lbs. And three winds. [/QUOTE]
