Un bolt. Remove. Mix some epoxy glue (I use automotive Bond) spread the glue and re-install the tip. Use masking tape around the joints and inside the luff track to help limit over flow. Place the mast on some saw horses so you can easily keep it aligned when the epoxy is setting up. I also position the mast base against a solid object (tree, post or wall) that I can push against when installing. You can slide it is and when meeting resistance pull the entire assembly back and "pile-drive" the tip into place.
