Hi Anders,

This weekend I finished the centreboard on Coot.  The finished width was 21mm.  I also took the opportunity to put some lead low down in the centreboard.  It is made up of strips 38mm wide.

I also came up with a way of making foils which helps me get a decent finish.  So I shall share it with you all.

Firstly make up your board etc.  Then mark the shape of the board in plan format and cut out to shape on the bandsaw or with a jigsaw etc.

Then I get a slot cutter on the router and router out the leading and trailing edges to their finished width.  I then fill the slot with thickened epoxy (silica and graphite).  This gives a tougher leading edge than just wood.

Then I mark the board in plan showing the limits of where the board should be full thickness.  It is then an easy job to shape down until the leading and trailing edges just show.  

Then on this one I have covered the whole lot in graphite epoxy.

Cheers

James
