This week I ventured into the world of HP boolit casting, and oh boy was I given a rude awakening. The learning curve with HP casting is quite steeper than with solids, and for the last few evenings I spent late nights figuring out what the optimal mold and alloy temperature, alloy composition, and cadence is in order to produce decent casts. Can't stress enough the importance of pin temperature, and it seemed that the only way to keep it consistent is to get a good cast rhythm going (baby shark FTW lol) . I managed to get a few hundred made, but it seemed that it was harder to produce good casts with the pentagon pins compared to the round ones. As of now I think I have a good idea of what to watch out for and how to get in the "zone" for HP casting, but I am open to suggestions and tips/tricks from the experts here. I'm wanting to be more educated and informed, thank you in advance!
