I am just embarking ( for the first time ) to make a new oregon mast for my 60 year old 40 ft motor Yacht. I know the method of creating a round one from square stock but I want an eliptical mast tapering to the top. Can anyone help with any info on this. Also I shall create a laminated spreader in oregon. I am not quite sure on the dimension the spreader should be ie length/ width in relation to the height of the mast. The mast will be 3.2 mtrs. ( sorry were metric in NZ. ) Any help would be apprecated.
