I was able to get full size plans for the frames of this design from a fellow in New Zealand. Using his CAD files, I was able to use a CNC (computer numerical control) router to cut out patterns for me to use in cutting out the frames. Sounds like a nifty process, doesn’t it? Well nothing is ever as easy as it seems.
I used the lofting we did to check the patterns, and found that they were not quite true to Nelson Zimmer’s design. The keel was a little flat. So I modified the shape of the patterns to fit my lofting of the plans. Next, we’ll use these patterns as guides for a router to cut very exact matches on the router table.
Any chance you could send me the contact details of the fellow in New Zealand that provided the design in CAD?
