Although I am sure there are shade tree ways to do this, the only right way is to use a pulley remover. This tool has a set of collars that fit over the groove in the pulley. Once that collar is in place a jack screw threads into a body that sits in the collars with the pulley.At that time you simply screw in the jack screw and the pulley comes off very easily K-D Tools has a nice kit, part # K-D 2897 but it is pricey.
(That is what I use in my shop) Harbor Freight has one pretty cheap. Good Luck.
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.
