Tiki 21. Parts layout on the 15mm plywood sheet.


I started to loft yesterday, making templates for the 15mm sheet of the Tiki21.

I take careful mesurements, then tried to put everything on the 1200 x 2400 plywood sheet. Impossible. I cannot put everything. I finished with no space for one rudder.

Mesured again, and agin. Same results, can't find any mistake on my side.

So, question is: did some of you faced the same problem? I will if necessary find a piece of plywood for the remaining part, but I'd like to know… Continue

About the Wood Triangular Section


All wood has been sourced now, but the "Triangular Section". Not able (capable?) to find it standard, (here in China, Shenzhen area )and since it is not in the form of a "square triangle", (BC² = AC² + AB²) I hesitate on what to order to mill it myself with my hand circular saw mounted on a table.

I am on a project for a Tiki 21, and the base of the wanted triangular section is 32mm, while the sides are 25mm. Or, "Imperialy speaking" base 1 1/4" and sides 1". (I just…

Epoxy coating


Plywood is ordered and will arrive soon. Epoxy, I'm still testing. However, I have two questions.

-When you coat plywood with epoxy, is it acceptable to put the second coat before the first is totally cured, without sanding, or is it better to wait that the first coat is totally dry, sand and put the second coat?

-I tried an epoxy yesterday. The seller made the mixture on a scale. I took two pieces of wood, dry. I put some epoxy mixture on both pieces, tied them and made… Continue

Thanks a lot
J'ai commencé mon petit catamaran sans avoir d'expérience de la résine. Et j'ai eu quelques hésitations et la peur de rater. Mais au final aucun problème sérieux. Donc, vas y fonce.
