Rename the Steam Turbine (blades) to Turbine blades, as it seems illogical to put a Steam Turbine (item) in a Steam Turbine (block). This was suggested by Su5eD, but due to a small mishap with threads merging, I write it down here instead.
Isn't there already a "steam turbine blade" item? That you use three of to get the "steam turbine" (item)? Renaming it to "turbine blades" would re-target the confusion instead of eliminating it. I think Su5eD also mentioned "turbine rotor" as a possibility, which would better alleviate the confusion, or perhaps the block could be renamed instead.
That must have been it, forgot what Su5ed suggested before I edited his post here. Fixed it now.
