Finished Drawing Cross Sections

Paige and I finished drawing up the 4 cross sections for her kayak last night. It was grueling work for the princess, but she got it done in the end. Once I had my question answered regarding the location of the keel stringer, drawing them out went pretty quick - a measurement to make sure the stringer location was a 1/4" below the keel and trace my stringer square. For most of them, I held the stand-in stringer (a piece of cardboard cut to dimensions) and Paige did the tracing.

The next step was to draw in the concave sides and internal cut outs. I referred heavily to Tom's example.

I measured out the 1/2" concave between the keel and chine on each of the cross sections. For this, I marked 1/2 way between the two points. I'd then measure 1/2" in from that. To keep my mind straight, I drew in light dashed lines to track where the curve started and stopped. Later my wife and I used the cardboard backing of a yellow pad to draw the curves.

Once the curves were taken care of, the next step was to draw out the internal cut outs. This went pretty quick - the top is 1 1/2" thick and the bottom and sides are 1" thick. For the tops, I used the ruler and drew out lines. For the sides, I cut out a 1" strip of cardboard and used that as a quick ruler. These came together pretty quick.

And, a side note- when I first bought the yard stick, I was surprised to see that it also had metric gradations. I have found that I use metric (versus imperial/inches) for a majority of measurements.
