I don't have a problem, I just need another minute to make this 4th assembly work at 100% efficiency, easy stuff, I'll just split a fifth of the output from the main screw factory so the iron rods can load at 20/minute and the screws at 100/minute, but wait, if I use a power slug I can go to 150% efficiency, although I'll need to add another coal powerplant to have enough energy so everything will be right in the world and I won't die on my sleep.
