[QUOTE="HonestAbe, post: 340811, member: 25390"] Hmm well my button is definitely larger sounding than it should be then. I know this is difficult without pictures so I will definitely post those tomorrow to make sure I am understanding correctly. If I want to do multiple crowns in the same ring (I often do 2),what I've been doing is forming a cone shaped sprue at the bottom of the former, then I take my two crowns and wax the end of the sprues onto the top of the cone in a V shape. In order to make sure they're not too far spread out to the side I've been melting the balls together so it kinda forms one larger reservoir. Like a venn diagram. I've experimented with different ways to have the crowns face but I'm not sure what's ideal and what's not. Should I automatically be using a bar if I'm doing more than one unit? With a bar, does the same principle apply about the button? Like the bar should be completely filled out with gold but barely have a button after that? [/QUOTE]
