Chine notches and Chine Logs

I am currently building a mckenzie double ender with a transom from Roger Fletchers book. I cut the chine notches in the following way, and am curious if it will work. The way I cut them slightly differs from the plans in the book. If you zoom in on the picture you should be able to see. I cut the chine notches at a 90 degree angle, (theoretically) eliminating the need for the bevel cut on the top of the chine log. Im sorry for not having pictures of the frame, I'm not near them right now, but am curious if this will work or if I will have to make some ammendments to the cut. One picture is of the unamended frames and the other is of the way that I cut them, the difference being traced in red. Thank You.  0202151526a.jpgboat%20frame.jpg

There may be an issue when you prepare your chine as you now have to determine the appropriate angle to cut it to match the new angle you made. Commonly the inner chine is a parallelogram with your modicication it will no longer be one. A secondary consideration is that now you have made a "catcher" of dirt and moisture which could encourage rot along the juncture of the chine and side of the boat. The original design formed an angle greater than 90 degrees which would encourage water movement away from the chine.

I am curious as to why you chose to modify the system that has worked so well for so long? What are the advantages you see to this amendment?

This is a great point, I didnt think about that. Well the man who milled my white oak milled it to the wrong dimensions, and with the parallelogram, it would be a very small chine log. I was not at home when he dropped it off, and by the time I noticed, he was 2 hours away. With this modification it would give me the ability for a bulkier chine. He was a nice guy who ran his own operation so I didnt want to throw up a fit, instead I tried to change the design to work with what I had. Maybe I will just get some more.

Thank you for the input, I really appreciate it. This site has been a massive wealth of information in the planning of my build.

I can appreciate your need for a change. Just think of this as an opportunity to learn some more. It probably won't be your last chance either!
