Form and shape the rails to the required shape and thickness and you are ready to remove the boat from the Jig. We used a hand planer for the rough shape and finished with a belt sander. It will now hold its shape and dimensions.

The jig can be used as a cradle to support the boat as you work on it either upside down or right side up. Once the boat is removed from the jig, it can be turned over and all joints filled with thickened epoxy. Install the dagger board trunk through the hull and epoxy in place.

Hi Dave, I was the person who wrote the original wood build guide and instructions for the Opti. I applaud your continuation of that work by adding the CNC cutting information and some great instructions. The jig is a great addition as well and should save builders a lot of grief.

I had always wanted to do the CNC cut files but once my daughter aged out I was not as enthusiastic as when she Build Your Own Optimist Dinghy Only was sailing the boat. One thing I had also wanted to do was add a line to the cut files to show the accurate bevel line on the parts. I would mark the line or lightly score with the router and then fully cut the part at the outside dimension so there was an accurate cut with good guidance for the bevels to fit.
