      Once i installed the taper pin in the head of my big red i will put some type of holding device on it so i don't miss place or loose it ( like a small chain ). I really don't see many reason's to remove the pin once it is in place.

      Phil, that's a factory thing on my mill. I've just been careful not to loose the pin :) . Mill is a Rong Fu JFC45N2F, I have had it for many years. Sorry for the confusion, Mike
