I didn’t weigh it before but I’m guessing 21 pounds. It was an interesting project.

Thanks It did stiffen it up a lot but it still has a good amount of flex but nothing like it did in the video.

Tks, I guessed you're using pine wood. I confess, I'm quite skeptical using pine... maybe here in Brazil the pine is different... look the same but I'm not sure about the resistance, the stress of the bending.

Never thought about it. Sounds like a good idea. Thanks

Thank you. It’s a gear 12 volt head motor that was originally used to swing out a stop sign on a school bus. Grainger sells them in various rpm’s and voltages. Depending on water your doing you might be able to use one of those tumbler or coffee cup spinner’s. Go with the slowest rpm you can find probably less that 10.

Thanks. No jig it was a router bit I purchased off Amazon.

It’s about right at 20 pounds. It does flex quite a bit but it’s proven to be very strong. I’m sure if you added more layers of material would stiffen it significantly. Also increase the thickness of the wood. Wall was about 5/16” thick on this mast. Pretty thin.

Thank you. 22 feet 4 inches tall. Yes it’s tapered and one layer of carbon. 2 layers on the bottom 2 feet.

I’ve never worked with that material before. I’m sure it could be done but not for sure if it would be good for a mast. Would be a neat experiment.

It’s a 12v gear head motor I salvaged out of a school bus stop sign. Grainger sell all kinds of these motors in various voltages and rpm’s. I got the idea from my wife she makes drink tumblers and coffee cups and she uses a similar device when applying epoxy.

Select pine from the hardware store. I used Duckworks birds mouth calculator.

The masthead is a hardwood plug separate from the hollow mast. Keeping things water tight.

The only thing I used was Duckworks Birds-mouth Calculator. www.duckworksmagazine.com/04/s/articles/birdsmouth/

I’m thinking it was about a pound per foot. I gifted that boat to another club member or I would weigh it for you. The staves were about.300 thick. It flexed quite a bit so I added rope stays but its still going strong.

I truly wish I would have done a better job getting more video for sure. Should have took the time to set up Timelapse of the assembly. It was not easy. No vacuum bagging on this project. Just used the rotisserie to get an even application of epoxy.

Your correct. There are parts of this I didn’t video because it was difficult to do by myself. I did lay all of the staves flat and roll epoxy on the inside portion before assembly. The test mock-up tube I did not. Things got really busy when it got assembled. Time was not on my side but we pulled it off. I highly recommend a helper when doing this type of project.

I never thought about filling it with foam.

It’s to late. It’s a done deal.
