[QUOTE="Zubler USA, post: 194186, member: 6881"] Hi McTeeth, I would love to tell you it is your furnace, but I doubt it is all furnaces get this result. Every time I see this, It has to do with Spruing. Your vacuum isn't the cause and a ring former isn't going to fix it, in fact it could add more issues, especially if it changes the thermal mass of the overall ring. I would look at your sprue angle, sprue guage, bevels on you attachments and sprue placement. all these are important. make sure you consider the flow of the material. [/QUOTE]
