Making the gar-board / top side

Firstly we used a spiraling plank to get the measurements from one side of the Gar-board. The spiraling plank is placed on the gar-board side of the frames and on each station a measurement from the chine to the spiraling plank at a known measurement in this case 200mm. The same from the bottom down.

After this is done we placed the spiraling plank on some cardboard and where we made all the chine marks we measured out 200mm out and same on the bottom marks but going the opposite way. after we have all the marks we then used a batten to fair the lines in then cut it out. 


We then placed the cut out cardboard on the sheet of ply and cut it out leaving all the excess ply on for we can cut it off at a later date. we make two of these for the gar-board is the same on both sides.


The exact same method is used to get the top sides.

Getting the correct bevel on the bottom

To get the right bevel on the bottom we used a hand saw and placed it on a station frame, got the hand saw level with the Garboard and cut the the bottom until the saw it was level with the garboard station frame. Do this on each station frame, but do not cut the frame it is just a guide.
After all the cuts a made we used a batten and fared the ends of the cuts in giving us a guide to plane to.

Jig for laminated frames and stem

We will be laminating the midship pieces and the stem. For us to get the exact shape we need we built a jig (but in this case we were fortunate enough to have some on hand). Firstly we printed out a full scaled lines drawing of the stem and tape it down. Then we screwed the jig blocks where we felt gave us an accurate guide for the strips of red ceder to rap around and follow the lines on the lines plan like in the picture and placed plastic over the jig so when gluing the strips it doesn't stick.



The strips of ceder is not flexible enough to bend around the jig so we steamed the ceder which makes the ceder soft and flexible then we clamp it to the jig to dry. When its dry the ceder takes the shape of the jig.




After this is done we un clamp the strips and start gluing the strips of  red ceder like as followed.
