Yo.
Im playing on server with ic2classic and found Fisher machine in wiki book. I try to build multiblock structure like in wiki, but nothing happened. Is this machine still in development? Or it is need something else to work?

the mod is completed and tested, while there can be bugs in it, a "Feature being unfinished" isn't a qualifier.
But semantics aside, did you put it into water? Where the logs are in water too? (On the same y level as the water)

Yeah, problem was about that, just rebuild it on same water level and it works. Thanks for fast answer!
