Made some progress on Friday afternoon. I ground down the seams that were sealed and rounded the edges of the box part of the tooling. I also fabricated two L-shaped brackets and drilled and tapped the base for them to bolt to. These brackets will be removable to allow the prepreg material to be formed to the box as well as to aid in removing the full part after curing. Soon I will fabricate a bracket to go between the tops of the brackets so that they do not flex during processing.
This picture shows the tooling as completed so far with a full-scale cardboard mockup of the center section. It fits perfectly.
This weekend or early next week I will be sanding and polishing the tooling until it becomes as smooth as possible. At this point we can determine if a gelcoat or paint layer is needed to get it perfectly smooth so that the part will release.
More updates to come
