5s vid , Q..how do i lower the heat?

that could be, i posted a few days ago and didnt get any info on which way the magnet should be on the shaft, i had a line on it , but it got worn off in handleing it so i didnt have that as a referance, but i glued it as best as i could so that the poles were fighting each other, i did a search and found a post where serum said the lines should line up, which was in the position where they fought each other when i pushed them together..............i may have been off on this but i thought it needed to be glued in the direction where they were fighting each other, like 180* out of rotation, instead of where they were stuck together(attracted to each other)


if i did it wrong that would explain why it was a p.i.t.a. to do, and if so how do i debond it?? acetone??
