Ok, site wasn't letting me add more pictures. This is another messy test of the concept (#2 the first used buttons to hit manually)in which I used a small startup engine setup I usually build into a basement wall with 4 boilers that can be upgrades to lava/blaze status easily. this one used only 2 with only needing a small cog to turn on the mech arm. The small cobble gen is using the threshold switch/redstone link combo engage/disengage the clutches to turn on/off the lvl 9 steam engine. I forget the exact range of the redstone links but the lvl 9 can be closer but still fed startup power from the "primer" engine thru the shafts. Hope the ideas spark more of your creativity.
