Next is new territory for me. Using the new tool and lining this thing up. Get the front motor mount screwed down. I imagine that gonna be a all day deal.
before i put my motor in what i do is shoot a lazer through gimble make sure its center then take measurements and mark dead center so when i put my front mount down i know im centered drill them and then i only need to worry about up and down .
Never tried the 1 inch pipe but I'm told it works well... you can usually look thru the gimbal bearing with a bright flashlight and get a pretty good idea which way it needs to go.
