3rd July 2015 – The center of the mast was to thin. It was solid, but I found it to risky to use it. If the mast falls, it is more then 1000kgs of steel that will come down. It took us a few hours to move the mast, remove the center and put a new one in. I used an old shaft as cent er. massive, heavy and wider then the previous one. I also changed the access to it. Now I can remove and replace the center much easier in case something would go wrong.
