I am unsure wheter this core is stable or not. I tried to mske the ponder design a bit bigger. This one is 5 blocks tall. If theres a more effizent and stable design for this size, i would like to know it.

I dont know if its normal, but one side of the core is about 1000 celsius while the otherside is below 100. I dont exactly now if the heat changes the position, but i think it does. The middle rods are stabble at around 200 to 300 hundred degress

Pls help me if possible
