I noticed recently that Tech reborn has no early way of making bronze because their version of a macerator (the grinder) cannot turn most ingots into dust (which is what it is intended to do, since its just a renaming of the macerator from the original ic2).

Bronze is needed for the wrench in Tech Reborn, so it would be nice to be able to obtain the wrench early on when first setting up your machines. Also it would make sense to just add in all the normal macerator recipes as well.
