When you cast do you use a flux to clean all the impurities out? I hate that when it happens. Nice job on the DRO
Not sure if I did or not with those bits - they were made out of the billets I pour with the left overs. Sometimes I have tried adding some pool chlorine but to be honest I'm not sure if it made any difference or not. These looked great when they has been just machined, no voids of impurities too see. But the caustic just ate them away funny so there must of been some inconsistency in the material.
