Bought a second hand Rockwell weed eater. cant work out how the line is supposed to be fitted. was told it uses short pieces of line.?

Because they are - the elements used are non-linear because nature/God made them that way and it is necessary to compensate in the design.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
