[QUOTE="ztech, post: 235747, member: 3022"] I have to disagree with the 10mm rule. That is part of the discussion only to prevent cracking of the investment. Since in a pressing operation, your melting energy is supplied from the pressing oven the closer to that heat you are with the thin sections the better they will press. The limit to this is so close that the ring fractures. [/QUOTE]
