OK, with the LE dry, we carried the wings carefully to the band saw where we clipped the LE within .5cm of the wing tip. Now, break out the 80 grit sanding block and carefully sand the LE just even with the tip. Done properly, the sand paper will not cut into the tip at all. The LE pieces each weighed 12 grams when I glued them on, so they sand down easily. By the way, everything from the cores and sheets to the wing tips and even the epoxy is weighed to ensure matching lefts and rights. I took the wing tip block, placed them against the tips, traced the outline onto them and cut them together on the band saw within a couple of mm of the surface. Then just enough Titebond is applied and the tips are taped on. Just a couple of pieces of tape are enough here. We will remove all of the tape at once after this step. After this dries, I will put on the overalls, break out some sanding bars and get things even with the sheeting.

Here are photos of the tips going on

Tips again.

OK, the LE and tips are dry and ready for shaping. We sand the tip down smooth first, and then shape the LE. The LE should be sanded to final shape because next comes laminating the center joint. The tips will be final shaped later on. The extra meat on them will help to prevent hangar rash on the final product. Here are a couple of shots of the LE and tips sanded down.
