New project: Build V6

Had I known it was that easy! Goosebumps.

Submitted by haggan on Thu, 10/23/2008 - 2:29pm



Started to "play" with kfoundry. Here is what I came with (first drawings).
What do you think ? How should I modify this design to make it better ?
Target is to build a canoe that surf well, track well and stays dry.
Two drawings attached : one with metric units, the other one is for imperial minded folks.

I have no idea if it will work. But it looks cool!

build it and they will come

Cool Hiro,

Did you build in the 'tumblehome' on purpose or is it an illusion of the drawings ?

aloha,
pog

Taken from wikipedia : (...)tumblehome is the narrowing of a ship's hull with greater distance above the water-line. Expressed more technically, it is present when the beam at the uppermost deck is less than the maximum beam of the vessel.

did it on purpose, may try to add some more.
What do you think of the overall shape ? Wide point is midlenght... does not look cool to me.
And rocker ? Deepest point is close to front iato... I have no idea what I'll get with that.

I like playing around with Kayakfoundry, very cool little program. Has anyone here ever tried to build one from this program?


#146 Mon, 11/29/2010 - 12:33pm


Yes, i have a partly finished stripper Oc2 from profiles printed from Kayak Foundry SW.

You can download the YAK file from here.

It's a good starting point and tool to create and study designs, but you still need knowledge like Bill has to get get the basics right.

Hiro, might help more if you also post the Hydrostatics/dynamics, some of the figures like coefficients etc can help identify a major problem. Something Bill could spot in in instant from profiles that we rookies can't usually shows up here.

Rambo, care to share some pics of your work in progress?

Hahha... no further advanced than 24mths ago ... only a few strips on a strongback. I need some of that Tahitian determination to get stuck into it and finish. Bonus is ... the strips are nice and dry !

numbers !


#150 Mon, 11/29/2010 - 8:45pm


I moved the wide point towards the stern, added some rocker at the bow, and made the hull rounder...
comments ? anyone ?

I liked the first one better.


#152 Wed, 12/01/2010 - 5:28pm


Hiro, have you taken any reference measurements off of existing canoes? Maybe use those as your starting off points and then tweak things from there. That way you are starting with something that you at least know has some good elements. You could eliminate a ton of variables that way...


#153 Wed, 12/01/2010 - 7:02pm


Haven't measure any canoe yet...


#154 Wed, 12/01/2010 - 7:34pm


Great to hear Hiro. once you have that big canoe sitting in your front yard you will be among the few. What Jc9 0 said is a good step with our canoes there is and average mesurment's for each canoe and if you sway, even a little it can make a big difference. of couse your tecnolegy is alot more advanced than ours. when I started building. an elder said to me you have a perfect canoe in your head , and always persue that. do not try to build somone elses or you could loose yours. I like the first one. you showed. It takes a year for a log to dry and its best to carve during winter so the wood dose not crack as much. Good luck

Nice Hiro ...

@ mulus : Thanks, my technology is nothing more than a chain saw, A4 printer and lots of adhesive tape for the forms, circular saw to cut strips, some planes, sanding paper and epoxy glue. We're not going to build a dug out from this log, we intend to build a stripped V6. We're going to cut 2" thick planks approx 10-15' long. Then let them dry. From this planks we'll cut 1/2" strips. So We'll have 1/2"x2"x10' or 1/2"x2"x15'. I have a canoe in my head but I know how I want it to behave, not what shape it should have ;-)...
BTW, no winter in my part of the world...

Hiro,

Suggestion....cure your lumber while it is in 'board' form. Then, once dried, mill them down to your 2" strips. If you mill your material down to 2" strips while the wood is 'green', and that narrow, you could encounter serious warping of the strips as they dry and render them unusable....much wasted time....not to mention material and the cost to mill....all which has to be done over again.....and you may not have another tree.....

Are you aware of how to properly stack the lumber to dry while waiting for them to cure so as to eliminate warping?


#158 Thu, 12/02/2010 - 4:38pm


Hi Bill,
Thanks for your suggestion. In fact I do not plan to cut strips before the build. I was thinking of milling a few strip at a time, glue them around the forms and then mill some others, ...

To dry the planks, I was thinking of something like this (see pic), without the roofing as it will be stored in a shed.


#159 Fri, 12/03/2010 - 12:23pm


The strips must be dry before building or they will likely warp.


#160 Fri, 12/03/2010 - 2:22pm


To expand on Bills suggestion. If you dry your lumber in "board form" take a brush and paint some lightly thinned wood glue or hot wax on the ends of the boards. That's where moisture escapes the fastest and cracks form first. I would even do that as soon as you have cut up the tree
By gluing the ends the wood has to dry "sideways" which is slower but more consistent and with less warp. I haven't dried wood in the tropics but would assume at least 3 months of drying if its a fast growing tree more if it's a slow grower.


#161 Fri, 12/03/2010 - 2:59pm


thanks, will do.

Lumberjacks gone wild !

That is some damm elemental and cool stuff Hiro.

Nice to see the best chainsaw in the world at work.
