Re: Modifying molds to improve melt flow
"Reeves", I also salute you for sharing hand casting tips even though you've graduated to spinning. Newer Do-its have way rougher cavity faces so every new mold I get needs to be resurfaced for more efficient castings release especially with cool expanding bismuth. Never messed with the gate because I figured that clean sprue break required a precision sharp edged transition where gate meets cavity. I think careful gate resurfacing might improve the flow and release properties of some other problem molds.
