<p>Hello all</p>
<p>I am about to assemble the wooden masts of my Tiki 31. I am using scarf joined Douglas Fir to achieve the acquired length. Since the temperature is low for using epoxy and for a faster assembly I am thinking of using polyurethane glue (mercola marine glue) which is also expansile and appropriate for small gap filling. Do you think I will have any problems with that both during the assembly and long term? The plans also suggest to coat the wood with epoxy on the inside before…</p>
<p>Hello all</p>
<p>I am about to assemble the wooden masts of my Tiki 31. I am using scarf joined Douglas Fir to achieve the acquired length. Since the temperature is low for using epoxy and for a faster assembly I am thinking of using polyurethane glue (mercola marine glue) which is also expansile and appropriate for small gap filling. Do you think I will have any problems with that both during the assembly and long term? The plans also suggest to coat the wood with epoxy on the inside before the final assembly. Does anyone know if epoxy works well combined with polyurethan glue and if not what can I use to seal the wood of the inside surface of the hollow masts ?</p>

I can think of two old guys I know that used epoxy to build their masts back in the 70's.<br />
<br />
On one boat, a ketch rigged ferro cement beast, the main mast was lost in 2005 after a rigging failure. Bad tang! This mast was laminated pine (he's cheap) and was solid. My friend towed the pieces back at 2 knots and we glued up another mast, also solid laminated pine, using epoxy. Anyway, that first mast had lasted about 30 years, probably with it's original coat of paint haha<br />

His mizzen is still fine...but he never uses it the lazy bastard.<br />
<br />
Another friend of mine built a beautiful 70' wooden gaff rigged schooner in Africa about 30 years ago. He used a swiss epoxy for his masts and has never had a problem with them. They are varnished and not especially well maintained.<br />
<br />
With both boats, the epoxy is protected from UV, and the wood was cured properly prior to glueing.<br />

My cedar is still drying for my masts, then they will be glued up with epoxy, glassed and painted.

we built our mast of vertical grain douglas fir. We are sorry we didn't go aluminium, lighter, cheaper and long term less maintenance. David <a href="http://www.boatsmithfl.com">www.boatsmithfl.com</a>

Thanks for the reply. I'll keep the Aluminum option in mind, I guess I have more research to do.<br />

We have wooden masts on Peace. They are too heavy for us to lift, let alone carry. I suggest alloy for weight saving because we could easy pick up alloy masts and carry them away. There are so many builders on this site, you could all club together and order together for cost saving.<br />
But if you just must have wood, I will say that ours are put together with resorcinol and they were made by Noble Masts in Britain. I put a thin layer of glass on them and we painted the masts. I am so glad we did…

But if you just must have wood, I will say that ours are put together with resorcinol and they were made by Noble Masts in Britain. I put a thin layer of glass on them and we painted the masts. I am so glad we did it that way. The thin glass protects the wood from chafe from the gaffs and the painted surface is easy maintainence. Varnish needs to be redone frequently in tropics and climbing masts with brush in hand is less fun than kicking back with friends in the cockpit as you sail along or just watch the days go by.<br />
