Ok I am posting my set up for ore doubling and you guys can see if you like it or not. It is a Manual Set up with auto compression.
Items needed:
1 chest
1 auto Compressor from Ex Com
2 pipes that move stacks
1 Autonomous Activator
1 Shiny Shovel (Mods Hammering, Luck maxed, Repair)
1 Shiny Shovel (Mods Smelting, Luck Maxed, Repair)
Set up:
Lead the chest into the Auto Compressor and then lead then compressor into the Autonomous Activator set to right click and Random. Use you hammering shovel to hammer down Gravel ore>Sand Ore>Dust. When you have dust put it back into the machine and then use your Smelting Shovel.
With this set up I got 5+ stacks of iron ingots from 1 stack of Gravel Ore broken down into dust first of course. Hope this helps some one. I am uploading a Video of the set up for those interested let me know and I'll send a pm with the link.
wouldn't a smelting shovel not just turn one ore dust into one ingot instead of two?
