I think since you're removing Poor and Dense Uraninite items, maybe you can remove the equally useless "Dielectric Rod (Horizontal)". You can just have a single Dielectric Rod item with a diagonal texture and maybe both a "horizontal" and "vertical" crafting recipe.

don't forget to add a recipe to convert them

Yup! Just takes up space.

I'm going to keep this for now because it's a fun (for me) peculiarity of the mod. :P
