I’m having issues with rattles that are not always working properly with my mold. Collins tube rattle molds
I’m pouring jigheads which calls for 5mm rattles. It’s not 5mm rattles apparently, it’s only one type of rattle which Barlow’s offers as “medium” size rattle. I’ve purchased identical rattles from other places which either don’t fit in the smaller weighted molds and that are also melting. The identical rattles from Barlow’s are also plastic and they rarely ever melt and they fit fine in all size cavity’s .
This is becoming a frustrating, time/financial drain on my operation.
Any advice?
