Quickie Book Ends

Mix RAEF, 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.

lt 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 designcd 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 worthwhile project to get familiar with the workability of thin BID and UND weave cloth.


To ease the engineer’s task of defining where things go in these odd-shaped gadgets called aircraft, a fairly standard system of references has been developed. Fortunately the Quickie is so simple that an eleborate measurement system is not necessary. It is, however, convenient to use the standard terminology for reference occasionally and you should be, familiar with its meaning.

The three basic references are called butt lines, fuselage stations, and waterlines. Don’t blame us for the absurd names, we didn’t set the system up. All three are given in inches from some arbitrarily chosen reference. So, fuselage station 100 is found 100 inches away from fuselage station 0, and similarly for butt lines and waterlines. Being as lazy as anybody else, we abbreviate these as FS , BL , and WL.

Fuselage stations (FS) are used to define the location fore and aft on an airplane. To make things easy, fuselage station 0 is generally located near the nose of an airplane and measurements are made aft. Fuselage stations are the most commonly used of the references and later on you will make a reference mark on your airplane to use as a permanent F.S. reference point.

Waterlines (WL) are used to define vertical locations. Waterline 0 is generally found near the ground and measurements are made up from WL 0.

Waterlines are utilized in many places to position components or templates relative to each other by leveling reference waterlines with a carpenters level.

Butt lines define positions inboard and outboard. Butt line zero is the vertical centerline of the airplane and measurements are taken to the left and right of BL 0. Since left and right depends on which way you are facing, it is standard practice to define left and right as the pilot would while seated in the cockpit.

Using these three references, any point in an airplane can be described with a fuselage station, butt line, and waterline. Fortunately, your Quickie is so simple that we don’t need to locate very many things this way. When you start on your 4/5- scale replica of a C-5A, this reference system will be real handy.

A pneumatic riveter is not required. The few hard rivets used can be set with a hammer, using your vise as backup. The "pop-type" rivets are pulled with a low-cost hand puller available at any hardware store.


Temperature has the greatesc etfect on the working properties of your epoxies. 75 degrees farenheit is an ideal temperature. The range from 60 to 90 is acceptable with the precautions mentioned in the section on EPOXY. Humidity has a lesser effect on these materials than it does on aircraft dopes and some paints. Humidity will only create problems if it is over 75%. Don’t undertake a layup if it is pouring down rain outside or, if you notice a cloudy “blush” on the wet epoxy surface, or any evidence of whiteness in the epoxy due to moisture.
