Sultana build log – Part 23

Assembly of the laser-cut pieces is complete (apart from the transom and rudder, which will be added later). Some observations:

The keel ended up being a little short. I added a little block at the end to fill in the missing material. I think the error is from underestimating the thickness of the rabbet strip. (You might also notice the garboard plank there. I forgot to take a picture before that was added.)

Sultana build log – Part 22

On the false keel, the cutouts for the masts are simple notches. The notches establish the forward and back angle, but do nothing to prevent side to side movement.

Let’s go back to Fusion 360 and imagine a part that fits on either side of the mast to hold it in the correct position. This is done in Fusion 360 by creating a little block and then subtracting the mast shape from it. The block is sized to fill the space between the bulkheads, so it also acts as a filler block to reinforce the bulkheads.
