I would like to make injection molded bocce balls, with a volume of just under 600 cubic cm. Has anyone played around with increasing the injector barrel size? Preliminary calculations: The current tube can hold around 280 cubic cm. I would need to approximately double the barrel's length or boost the barrel ID up from a 26 to almost a 40mm, if I was to keep the barrel length. I'm nervous about increasing width due to increased heating time, but increasing length will require a rework of the system for the lever arm. Right now, I'm leaning towards an increase in width. Logistically it seems the easiest. Any thoughts? Has anyone had success in a barrel volume increase? Cheers, Ders
