Inflection

OK, so it’s been another two days without a post. Well, I have the same excuse as before, I am trying to have a life outside of kayak building; and guess what, I am succeeding at least a little. This time it was Ethiopian food (along with wonderful company) which I have missed terribly since visiting that fascinating country.

Back to the kayak: I decided to change the profile of the kayak at the bow and stern. I wanted a more rounded end, rather than the pointed end the design calls for. This will allow me to wrap a series of thin laminations from the keel line around the bow (and stern) over the rounded end and onto the deck. I am hoping this will make for a strong and pleasing way to finish the ends.

I had been dreading (and putting off) the inflection strip – that strip which will define one side of the sharp corner that marks the transition from the high deck to the low deck (you’ll have to read some of my other posts to know what this means.) I had it built up in my mind as being very difficult, and like most things, the difficulty quickly disappeared with the doing of it. I had to plane angles on both edges of the strip and also adjust the width of the strip to match the space remaining according to my plywood stations. I had visually adjusted the gap to be about 1/2″, but with the angle of the strip changing along its length, it was impossible to keep it constant, but the block palne made quick work of it. The end result (I think) looks pretty good. I had to join a few pieces of palownia together to make a strip long enough for the entire kayak. I’ve been using hot-glue to temporarily hold the skarfed glue joint together – this way I don’t have to wait for the glue to dry. I use a small scrap of strip on either side of the joint to sandwich it.

I also encountered problems with the tape I use to apply pressure to the strip while gluing. With the inflection strip being at a different angle, it means the tape doesn’t lie flat along the kayak, but has a gap underneath it. This allows the tape to release quite easily, and unless you are using a long length, it just won’t hold. My solution: clothes-pins. They hold the tape onto the strip I am installing and I can then put a lot of force into the tape as I stretch it down onto the kayak which closes up the glue joint.
