As only one layer was put down first, for stress management, the subsequent layers would be laid in hard epoxy. In the past we had been told to sand first, but that is not really important, as the matrix is only a day old. What IS important is to have a smooth surface, and as fibers conform, they stretch and pull, so the real reason for my sanding is to smooth out any stickies.

Then two more layers, and a heap full of CF scrap's were cut, and after one more full sheet, then all the scraps were laid down, followed by the final full sheet. I estimate most of the areas have 6 layers of 6 oz. 2x2 twill. Good enough to still flex a bit when separating the two pieces, and then a good foundation to strengthen the mould, as that will be explained later.
