I hammerfed the thing with a bajillion re-iron and we came out with 18 HV arrays.
I took them and set up a re-iron plant on Arrakis, it's phase piping re-re iron directly into the plant chest on channel 223.
If you get a wild hair and want to do your scrap magic, you might have to phase pipe the scrap into the thing because I jammed it in the corner, but whatevs.
