Re: Making a birdsmouth catboat mast
Oh, sorry. I thought that worked in English. Google translate says - Lamell: Lamella, slat, louver, spline....
A flat wooden slat the bredth and length of the mast... Like when you laminate something.Comment

Re: Making a birdsmouth catboat mast
I see you have a Dragon... would you consider a birdsmouth mast for that?
I have also considered splitting my present solid wood mast and glueing in a lamell the entire length of the mast. That would certainly stiffen it and may be the best option. But I'd consider beginning from scratch and keeping the present mast intact if this birdsmouth construction can be made strong enough in the diameter I need.
But at present, I'll just continue to follow Jim Ledgers progress and enjoy the thread.
From what I've observed from the builders here you should well be able to make a suitable mast to the dimensions you gave. One unusual thing about a catboat mast it is that is essentially free-standing. The only standing rigging is a forestay, which hangs slack unless you're sailing upwind. My point is that your mast is probably supported by standing rigging, which would take a lot of the load off the mast itself, giving you a margin of safety that I don't anticipate in my boat.
Making more shavings...

Yes, Thanks. That was supposed to be a reply to Duncan's post - #78. I don't seem to have the hang of the hybrid posting thing yet...Comment

Re: Making a birdsmouth catboat mast
This is only mast building picture; http://www.freewebs.com/maryii/apps/...otoid=43532452 , my computer get down and...
There are, in post one, on launching pics of ready mast; http://forum.woodenboat.com/showthre...5-Gartside-109
and post 49 are pair of pics when mast was taken of to winter storage ( note huge amount of people in pics, crane man haven't come yet and I took pics, )
In service the mast have worked well, only two and half season this far. Mast is quite slender 170mm diameter, 70mm on top, the top length is for topsail. http://www.freewebs.com/maryii/apps/...toid=140093172
I had 7 m long, 2" through sawn spruce "on shelf "(one time I had a idea to build strip plank sailing boat, but I made plank on frame instead.) so I needed only two scarfs to each stave."Simplicity, Clarisse! First principles..."Comment

Re: Making a birdsmouth catboat mast
You're darn right it was, Gary, I've been following your instructions to the letter. Thanks!
Is there some way you could post it here? Judging from the amount of interest shown here I'm sure it would be a welcome addition to our fund of information.
For the rest of you, Gary has published an article in Junk Rig Magazine detailing his mast build. It's well written, informative and has a nice set of accompanying photos.Comment

Re: Making a birdsmouth catboat mast
Jim,
Thx for posting this and organizing the additional information. A great resource which I will need in the future, I only hope I can first complete the platform on which it will rest.
Best,
JonComment

Re: Making a birdsmouth catboat mast
I've had a think about it and I've submitted it to Wooden Boat as a possible magazine article. If they were to publish it then I would have the $$ for the safety gear i still need to sail the sea.Without freedom of speech, we wouldn't know who the idiots are.Comment

Re: Making a birdsmouth catboat mast
That's a great idea, Gary. I was going to suggest a thread of its own, because it would be easier to find in the future, but a published article would get the most exposure. Good luck with it!Comment
