Going to repace a wood keel in my recanvased 100 year old canoe. Got a question regarding the materials. Thinking of using a #8 18-8 stainless steel finish washer with a 1 1/4 inch silicon bronze wood screw. Placing washers and screws about three ribs apart. The keel is 3/4 inch thick. All items can be purchased from Jamestown Dist. or Merton's. Any ideas, comments or suggestions would be appreciated. Ron
