The lofting board has half of the frame drawn onto it. I want to notch down in the middle of each frame for the keel, so for each frame I need to figure out how wide the keel is supposed to be in that part of the boat, add a centerboard space, and add that length to the overall frame width. Be sure to account for the other half of the frame as well.
Frames are drawn on the lofting board to the outside edge of the frame, where the plywood attaches. Boatbuilding is such a surreal 3D process - pencil lines have to become the edge of a board with no width defined, just an edge. And even that edge is going to get planed to an angle so it makes flat contact with a bent piece of plywood - imagining the finished frame by looking at a pencil line on a piece of plywood is intimidating.
|The first frame!|
|It's a bit wider|
It's important to note that you don't use a tape measure for any of these cuts besides the keel spacer. Everything length and angle gets taken directly from the lofting board! It's such a surreal process.
|Frame 3 - used a piece of scrap 1x3 to hold the bottom in place|
|Frame 3 and 4 don't have a top crossbar so I used these plywood scraps to hold spacers|
|This looks like frame 5|
|I might plane these some more later by hand. Still a bunch of gray showing here|

Finishing the frames is an incredibly cool first step!
