Hollow 12 sided wooden bird’s mouth sailboat mast covered with a woven biaxial carbon fiber sleeve

Great job! Can't wait to see it sail.

great video. Did the carbon fiber stiffen it up some? Looked kind of flexible when just wood.

Nice build. What's the total length? Is it tapered? How many layers of carbon fiber did you put on?

Nice build, do you have a jig for the 24 or 12 taper pieces?

That is down right beautiful.

Nice looking job. Also - jealous of your shop tools.

you are a champ well done

What was the software that you used

Good evening. Which wood did you use? Which software to calculate the sections. Tks

How to you prevent water intrusion through the holes at the top?

Will, that looks great! Appreciate you sharing the process. How much did the mast way before hardware?

Did you think of a expandable foam inside the mast? displaces moisture and stiffens a bit more.

What is the motor you used to turn the mast when applying epoxy to the carbon fiber?

🤔 unless you completely seal the inside of the mast. It will definitely rot from the inside out.

Oh dear, firstly you missed out showing the only difficult bit, gluing up the wood and getting it assembled and clamped up. Then the most useful technique with sheathing, vacuum bagging.....

do you think it could be done with divinycell instead of wood? building each half and glassing both sides... then gluing both sides...

Great job in describing the process. I'm particularly interested in the geared motor that was turning the mast during the post-processing. Is that something you bought ready-to-go or did you make it up? I could really use something like that in our shop.

Very nice, some good mfg. skills there.

Pretty cool project. How much does the mast weigh? I'm building a Farrier F22 trimaran and I've been trying to figure out how to build my own mast for it. Maybe I could use this technique. I think the Carbon sleeve would work well, but I think it would need a few layers of unidirectional as well.

Fill it with hard foam, coat it with polyester Fiber epoxy

Carbon fibre is toooooooo stiff

Can you provide a link to the mast design program?

Good stuff, so aprox weight per ft after laying the carbon fiber & epoxy?
