.....Mix Safe-T-Pox, make a small batch of slurry,and save the remaining epoxy. Slurry the foam surface and apply two plies of BID to the contoured surface. Start the layup in the center and work out toward the edges. If you have trouble getting the glass into the depression corners without bubbles, lift the plies and wipe in a little dry micro. You will then find that it will lay smoothly in without voids (see sketch). This depression is sharper than any in your airplane and is intended to give you a feeling of how sharply you can form the cloth.
.....Before laying the third BID ply down, place your favorite photo in the depression, and then lay the third BID ply over it. Scissor trim the excess glass cloth. Allow to cure and knife trim the edges. The lower edge is trimmed flush with the bottom of the foam block.
.....Wait until the second layup is fully cured. Remove the 1 inch foam block with a butcher knife and sanding block. Remove foam for a 1/4" flox corner and sand the glass surface dull.
.....Mix Safe-T-Pox, a small batch of flox, and a small batch of micro slurry. Fill the corner with flox and slurry the foam. Lay up the four UNI plies with the orientation shown.
.....Knife trim the edges. After 12-hour cure, sand the edges with 100-grit sandpaper as required for smoothness.and good appearance.
.....It may at this time seem a bit ridiculous to use three layups, about four hours work, and two days cure, just to make a book end! But remember, this book end was not designed for ease of construction; it was designed instead, to let you get a first hand exposure to the following operations before starting on your airplane; glass cutting, foam preparation (slurry), BID and UNI layups, flat surfaces, corners, and compound curves, flox corner, knife trim, concave and convex foam carving, glass to glass surface preparation, and sanding edges. So, use this experience to your best benefit and spend the curing time studying the plans. Even if you're experienced in glass layups, the book end is a worthwile project to get familiar with the workability of this BID and UNI weave cloth
