[QUOTE="HonestAbe, post: 343932, member: 25390"] Still getting porosity sometimes at the sprue location and I'm not sure why. I can't tell if it's adjacent to where the sprue is or directly where it meats the pattern. My gut is telling me it's something to do with the way I'm attatching the sprue (too broad perhaps? will get some closeup pics of next ones I do) but others here are insisting it's because my button wasn't big enough.
