After some research and trial and error, I have come up with some ideas as below.

I'm not going to make holes or chisels in the bamboo.

Bamboo can be peeled.
So I intend to cut the bamboo across to about 90 - 95% and then leave the peel to hang.

This peel is fibrous and can be bent over the connecting pole. Now with the peel bent, start to lash like mad. Tight lashing using the right thread will enable a strong hold and no slipping.

Now the Strong Back Issue:

I think I was confused with too many articles and pictures on Strip Building and Conventional SOF kayak building! Now that what I do is not conventional, I had to pick up so many ideas from so many other construction methods and cook up a unique one...

* This picture is a drawing I made on paper to show how to proceed without Jigs of Plywood. [http://www.boatdesign.net/forums/attachments/stability/27852d1230117176t-small-kayak-under-13-feet-stability-img_5963.jpg]

* The two gunwales are lashed to a Bow piece/Stern first (may be a cross cut miter would help)

* Then the first Deck Beam is lashed at the right interval one side at a time, to both the gunwale.

* When this is done the gunwale start to take shape, and wont slip, I have shown two beams lashed in the drawing.

* When all the beams are lashed, the gunwale will be a fully bent boat shape, lash it to the Stern.

* What I propose is to also lash the ribs at this point at the same joints as the beams, leaving the stringer side hanging...

* So what you will see will be some thing like that in the drawing..

* And then I can lash the stringers to the Bow and Stern, then the hanging ribs should be lashed to it.

This way a strong back is not needed. Only a couple of saw horses to mount the frame for easy lashing height.

What do u guys think?

I do not know how this will be numerically correct. It can't be, it must be a very very ancestral way of building the water craft, this is what I can do now, without tools.

I can't imagine how the Sea Bee's numeric would go into this sort of building?
I have started to loft the offset table of the sea bee to poster boards, but still wonder how would that help me? [Tom please throw some light on this]

1) Roughly I can follow the intervals of the ribs, and the beam of the sea bee.
2) I may not have a multichine, though it is possible
3) I cannot have a rocker, though it is possible remotely.
4) Knee Beam could be bent and managed.
5) Flooring can be a bit of plywood strips.
6) No idea about the coaming! - two thin bamboos can be lashed together and coaming made!

What do u people think?
