Fairing the Frames and Stringers

With all the stringers finally glued to the frames, I could move on to the next task: trimming everything to create a smooth, even surface onto which the plywood hull panels would eventually be fixed. This step is important because the plywood needs to make good contact with both the frames and the stringers. Any gaps would mean poor contact and, ultimately, a weaker bond.

Using a plywood strip to check for good contact all the way along

To check how well everything lined up, I cut a long rectangular strip of plywood, about 15 cm wide. This would serve as a guide, simulating the position of the final hull panels. I placed it along the boat's skeleton and checked whether it made proper contact all the way along, without leaving any gaps. Whenever I spotted one, I looked for the nearest contact point between the plywood and a frame or stringer. That was usually where I needed to remove some wood, gradually reducing the gap until the plywood sat properly against the structure.

For trimming the excess wood, I experimented with a power plane. It certainly removed material quickly, but I found it noisy, heavy and rather difficult to control. A small mistake could easily remove more wood than intended. I then tried a regular block plane and found it much easier to handle, especially when working more carefully.

In the end, I used a combination of tools. The power plane was useful for removing larger amounts of material, particularly around the frames towards the bow, where the curves are more pronounced. I then switched to the block plane for finer adjustments, and occasionally even used a file for the smallest details.

One thing I learned was just how important it is to have a properly set up, sharp plane. At first, progress was painfully slow, so I asked for some help at the boatyard. Someone took the time to sharpen the blade and check its settings. The difference was remarkable: after that, I could remove wood with much less effort and make progress considerably faster. A good tool really does make all the difference!

Trimming the bottom

Initially, I marked the points where the plywood strip made good contact with the frames, drawing a few lines to give myself a sort of map of where material needed to be removed. As I gained experience, though, I started developing a better eye for it. I could quickly inspect the surface and work out where the plane needed to go. It was also helpful to look at the plywood from inside the boat, to see how it was sitting against the frames and stringers.

Towards the bow, the curves become tighter, so things were a little more challenging. In some places, I had to plane several frames at once to create a smooth transition, allowing the plywood to be pressed and bent across them without being obstructed by one frame or another.

Overall, I found this to be very satisfying work. Little by little, as I removed the rough edges and uneven corners between the frames and stringers, the shape of the boat started to emerge more clearly. By the end, a fair, continuous set of curves had taken shape. It was one of those moments when the structure began to look much more like an actual boat.

Most sharp edges removed - fair curves appeared

There is, however, one issue I still need to address before moving on to the planking. I made the mistake of setting the 5 cm stringers at the corners of the frames too deep into the structure. As a result, there isn't enough material left for me to plane them properly and create the correct corners between the bottom and sides of the hull. The solution is to glue some additional wood onto these stringers, giving me enough material to shape them as needed.

The boatyard owner had actually spotted this problem months ago, with little more than a quick glance at the structure! His experience clearly counts for something. Still, he reassured me with a comment that made me feel better about the extra work: "Don't worry, after you glue the additional wood, your stringers will be even stronger."

I'll take that as a bonus! I just want to get this last job done so I can finally start planking the boat. I'm getting rather impatient to see the hull take shape.
