My take on porting the angels smelting and compression expansion mod from p.o.d for 0.15, I have extended it to be more in-line with bobs and angels updates for 0.17.
See changelog for more details.
Differences exist between this variant, and the one by Darknova
Compression: Takes angels sheet and wire coils, and adds more metals to the list of coils
--Allows productivity in un-coiling for late game super compression
Alloy Smelting: Adds an option to use molten metal mixing to make alloys, instead of ingots
Ironworks: Adds production of gears and pipes (and underground pipes) direct from molten metal
Ironworks: Now with angels components support
