Guess you could say it "sits in a pocket" but it's pretty solid there. Putting a pin through the back of it would take several hours, plus I would probably have to make up some new lines.. and this is my time of year to split all I can, gather all I can, etc etc before the weather gets unbearable. I will probably work on something to keep the cylinder from going towards the wedge if this ever happens again, but it's going to be fast and dirty! One of these days I am gonna build a bigger and better splitter with a 4 way and I'm gonna do that one right!
