A year or more go there was a discussion about Al sprue plates. I have had a 12x12 pice of 1/4” 7075 waiting to be used for a sprue plate but had no good way to evenly space holes, etc. , that is no longer an issue.
Got it rough sawn, cleaned up the sides, measured and marked holes. All drilled, and done except for a little thinning with the flycutter. The sprue holes aren’t sharp enough yet but the flycutter will take care of that.
