Is there any particular reason why the rock crusher has to rely upon another mod like IC2 for ore doubling recipes? I would like to use Railcraft as standalone more or less, and it seems like requiring an entire second mod for the sole purpose of adding rock crusher recipes (the addon mod specifically designed for which has also yet to be updated to 1.7) is rather tedious.

Mainly because I'm not terribly fond of how easy "ore doubling" recipes typically are to achieve.

I have plans to add more ore processing, but it will not be "grind this to get 2x the ore".

I only added the recipes in the first place so that people wouldn't need a Macerator if they had a Rock Crusher.
