Work continues on creating CNC files for John Welsford's designs. So far I have created CNC files for Light Dory, Longsteps, Navigator, Pathfinder, Scallywag, Sei, Tender Behind, Walkabout and Pilgrim. Sherpa is currently in work. Others will follow.
If you're unfamiliar with CNC files, they are 2d vector (.dxf) files that you can bring to a CNC operator. He will then use these files with his CNC machine to cut your parts out of 4x8 sheets of plywood. Below, you can see which parts will be cut out and produced by your CNC operator for each boat (click to enlarge). This will save you a tremendous amount of time and possibly mistakes vs drawing and cutting the parts out yourself. Note however that not all parts are included. Parts such as bulkheads, centerboard cases, transoms, doublers, lower panels, planks (on some boats) and other parts that are defined on John's drawings are included, but parts that are cut-to-fit parts usually are not. Cut-to-fit parts include parts like seat tops, decking, and usually planks. Those type of parts are made by clamping an oversized piece of plywood to the boat, tracing the outline of the part, then removing and cutting out the part. Also, some parts are intentionally slightly oversized by design so that they may be trimmed to the exact size on installation. Better too big than too small.
We are still working on how to make these CNC files available. Stay tuned.
If you have the plans and are in need of a CNC file for a boat you wish to build, you may contact me at j_bergen@yahoo.com and I might be able to help you.
