Quickie 3-View

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.

ATMOSPHEREIC CONDITIONS

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.
