If somebody is interested in “guessing” the final weight the wood weight glue included will be something around 6,5 kg. The mast I already made had a wood weight of just under 5 kg, and I used spruce instead of WRC on that one.The calculations are adjusted by a sharp plane.
There is another thing that is troubling me a little. If we shift to all carbon my method of joining the strips by glassing them together will result in some completely useless extra weight in glass, but I don’t see myself doing it with carbon. In that case I would portably have to put all the carbon going on the inside and bag it.
