COMPOSITE MATERIALS EDUCATION | ||||||||||||||||||||||||||||||||||||
.....DON'T SKIP THIS SECTION. Every hour you spend in this preparation section will save you five when you really start building your aircraft. INTRODUCTION ..... In this section you won't build any part of your airplane. What you will do is learn how to build your airplane the right way. The construction techniques may be radically different from anything you've done before (including building boats, surfboards, airplanes, and gocarts), and you should assume there is only one correct way to do it. We've discovered many wrong ways of doing things and have written the plans to keep you from repeating our mistakes. We insist that you do things our way. If you have a better idea, suggest it to us; we'll test, and if it really is a better idea we'll publish details in the Quickie Newsletter. .....This section will teach you all of the techniques required to build your airplane, show you what special tools you need, and how to use them. The educational samples that you will build in this section are designed to give you experience and confidence in all of the techniques that you will use in the construction of your airplane. The steps in construction of each sample are arranged in sequence (as are the steps in construction of the actual aircraft parts) and you should follow the sequence without skipping any steps. You will learn the basic glass layup technique used throughout the aircraft, special corner treatments, foam shaping/cutting, and joining methods. A summary of these techniques is provided on yellow paper for you to tack up on your shop wall. THE FOLLOWING TOOLS ARE ONES YOU MAKE: Sanding Blocks ..... These are required in many areas during construction and for finishing. You may also use a "soft block", which is a block of the blue-white or orange styrofoam wrapped with sandpaper.
Long Straightedge ..... This is not absolutely required, but is quite handy when jigging or checking the straightness of flying surfaces. It is merely a 6-ft or 8-ft lx3 or lx4 piece of lumber that is hand-selected to be "eyeball straight". You can get it one of two ways: (1) Order it from Aircraft Spruce & Speciality Co., or Wicks Aircraft Supply - they plane them perfect from dry lumber. (2) Sort through the lumber (dry fir or redwood) at your local lumber yard until you find one that looks straight when you eyeball it from one end. Mark it and hang it on the wall so it doesn't end up as part of a shelf! Epoxy Balance ..... Devices which automatically ratio the correct amount of resin and hardener and dispense it with the pull of a lever are available from Aircraft Spruce & Speciality Co., and Wicks Aircraft Supply, for approximately $150. These save time and epoxy. You can ratio the epoxy by building the following simple balance - don't skip steps! .....Follow each step exactly every time you mix epoxy.
Hot Wire Cutter ..... You will need a hot wire cutter to carve all the foam cores for the canard, vertical fin, and wing. Refer to sketch.  | ||||||||||||||||||||||||||||||||||||
