Well this weekend I started my project.<br />It is a 1991 sea ray 160.<br />I thought the floor was bad, but i didnt think it would be this bad. To start it off i tried to remove the rear seat frame, but it was not coming forward. To find out previous owners solution for a soft floor was to put a new floor over old rotten one. so now have top floor and bottom floor. the bottom floor was so bad in the middle that it broke under slight finger pressure, same with the tops of the srtingers. now i have a little over half of floor and foam removed. i was wondering what is the best way to get the floor away from the hull on the sides. and whatever method i chose is that the same method for the stringers.<br />i also was suprised to notice that the support between the stringers does not go all the way to the hull edge. there are only two supports for the stringers that just run between the stringers, with foam running the whole length of both sides. once i cut into these srtingers and start sanding and/or grinding can i stand in the middle of the hull like i am currently doing with the stringers in.<br />what kind of sander/paper or grinder/disk will work best.<br />the stringers seat frames and all others are made of 1/4 plywood with a plywood lip around all edges for fastening (i think). should i change any of this or do it the same as factory with lots more resin and fiberglass atleast on the tops of the wood.<br />thanks to all other projects for the info.<br />and i am taking many pics, and hope to make a web page to help as much as they have helped me.
