Is anyone familiar with their method shown as the joggle stick marks are transferred from the boat section to the construction (pinkish) paper? Is it done directly or on a separate flat surface?

There was an article in WB a few issues back on using a joggle stick. One picks up marks off the hull with the stick outline (unique steps of the stick) are than traced on a piece of plywood securely anchored on the same plane. The plywood with the lines drawn is brought to the drawing board or place where the stations or ribs will be fabricated and the joggle stick marks the point picked up.

At least that is my plan for redoing the ribs on the Concordia. I'll let you know how it works with pictures when I get there.

If you look at the first several pictures you can see some wide stock horizontally above, or vertically beside, the boats. I believe (having done something similar), that the paper is attached to them. The horizontal will give the line of the backbone, rabbet, etc, and the vertical is for the sections. No doubt someone will come along and tell me why my eyes are brown.

I can imagine a piece of thin ply attached to the framework Ed notes, and then getting joggle notches on paper tacked to it. That would make sense to me.

I used to live in a 100+ year-old house without a single straight wall or right angle in it. I did lots of restoration, and often used the joggle stick to fit things. It works remarkably well. It's just a matter of matching up the planes, as noted above, so that the measurements are taken on the exact same plane that you're going to transfer the shape to.
