Shaft Junctions are used to merge or split torque (and subsequently power). To merge two inputs, both inputs have to run at the same speed. Note that only up to four engines may be combined with basic shaft junctions, but they may be upgraded by simply right clicking it with a bedrock 2x gear unit, this consumes the gear unit and changes it to a bedrock shaft junction which has no engine limit.

Rotarycraft Handbook DescriptionEdit

"The shaft junction does exactly what it sounds like.  In 'merge' mode, it will take two engines' outputs and combine them, outputting the sum of the torques at the input speed.  Note that trying to combine inputs of different speeds will merely result in a shower of sparks.  In 'split' mode, they will take an input and send some torque each way, at the input speed.  To swap modes, shift-right-click with the screwdriver."


In split-mode right-clicking the junction will bring up a GUI that allows to configure the ratio in which torque is split.

Screwdriver UsageEdit

Right Click
  • Turn
  • Change input/output positions
Shift + Right Click Change mode (split or merge)

Tips & TricksEdit

  • AC Engines can have varying shaft speeds depending on redstone clock rate.  This may cause undesired results with shaft junctions in merge mode.
