How in the world? O.o in Tekkit Classic Discussion Posted June 15, 2012 Well gravel can be repeatedly broken using deployers to place gravel over a torch. The gravel then falls at least one block to break into either gravel or flint entities. This can then be picked up by a transposer. Gravel can also be macerated into flint, but this requires EU whereas the other method doesn't. You didn't really provide enough info to figure out more than this, but i hope I've given you a good lead.
