3/4 drill or hole saw?

Drill press.... Build a jig to hold it tight in the drill press that will hold it
at the same degrees to do a small pilot hole in each runner, slow as she goes with lube and a good bit... at slow speed go to a little bit bigger then the first one and so on, I don't know But I would think building a jig to hold it as I drilled would be the hard part ,,,,,, yes a machine shop would be my choice
