Wasn't too bad. I've been running my diamond ore and coal ore through the sag mill since fairly early on, so I had the 405 diamonds for bedrockium. Did end up getting some diamond armor through villager trading and breaking it down, as well as using the coal blocks to diamond recipe in the compressor. I was NOT going to even try the way that requires 200 million cobble. I could probably pull it off now, though, since I have stupid amounts of iron for building world interaction upgrades.
Speaking of lots of ore... If you haven't built a mekanism ore processing system yet, design it with multiple chemical washers. That will be your bottleneck. I don't even have space to pull out the one I have and run pipes, I can't stomach the thought of tearing up the whole thing and rebuilding it either. A work of freaking art it is. Self contained sulfur generation, attached sugarcane farm to make biomass for ethylene off the excess hydrogen, etc... Blasted mod needs to learn to work with aluminum though.
