Some ... ah, Observations re starting in 'don't use all the same old lame mods mode':
* Immersive Engineering pipes seem to have trouble inserting fluids into Forestry or Railcraft devices if the water is being auto inserted via a (e.g.) Railcraft Water Siding. Perhaps they need to be pumped? But the IE pump is ... somewhat unobtainable at the start.
* The Hobbyiest's Steam Engine is a trap. It burns a piece of coke coal for 4800 ticks (not the 3200 the tooltip says!?) - assuming it is producing the proper 20RF/t that is 96000RF per unit of fuel. The automatic sifting table takes 8000 RF per operation, so each piece of coke coal yields a whopping 12 sieve operations. Of course, it takes a long time for the Steam Engine to reach full speed, so it mostly does about 16RF/t, - which means each piece of coke coal generates enough RF to do ~9 operations. And, when Sifting Gravel, you can expect 1 piece of plain coal per 9 operations. So you can probably break even on coal as long as you turn it all into coke coal, only operate the Steam Engine at peak speed, and never use the RF for doing anything other than sifting Gravel.
* The Railcraft Rock Crusher is also a trap. 24 diamonds get sunk into a device that uses 16,000 RF to crush a piece of rock. It also has not been taught how to produce Ex Nihilo dust. By contrast, the other "crushing" machines use 3,200 to 1,600 RF per operation (I'm not sure what RF equivalent the Macerator uses as, given the tech tree, that is probably the most accessible of the lot). It also maxes out at 160RF/t, so at full speed you are looking at 100 ticks per crush operation so it can, with sufficient power, outpace an unaugmented auto sieve (which takes 200 ticks per operation).
