I purchased two masts for the O'pen skiff per the directions and finally got the nerve to modify one of them to be the mizzen mast. I was very careful where I made the cut, but I found that section 4 still won't fit into the inverted section 2 as per the directions. There's still an aluminum layer inside that makes the cavity much smaller. I'm not sure if the mast design has been updated over the years or what. Has anyone else run into this and what did you do about it? Thanks
