DON'T SKIP THIS SECTION. Every hour you spend in this preparation section will save you five when you really start building your aircraft.
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. This construction technique is 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 lots and lots of 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.
There are certain tools which are necessary to complete the aircraft. Three lists of tools are provided here. The first is the absolute bare minimum required, sacrificing efficiency; the second is a recommended list for the best compromise of cost and work efficiency; the third is a list for the “Cadillac” of shops where ease of construction is more important than money. The non-common items are stocked by the Quickie distributors.

- Recommended Tools (in addition to those above.)
Dremel-type miniature high-speed hand grinder with saw and router bits.
6” to 9” disc-type hand sander
Set of 1/4”, 1/2” & 1” chisels (wood)
Small set of X-Acto knives
1/2”-dia 100° counter sink (piloted)

Approx 150 lb of small weights *
* Weights are used to hold various parts down while epoxy cures. They’re bear in 5 to 15—lb pieces. The items in the photo work great. We got them for 5¢/lb at a local scrap yard. Sand filled milk cartons also work well.
- For the First Class Shop (in addition to those above)
Epoxy ratio pump (Michael Engineering Dispenser)
90° drill adapter
Air compressor with blow nozzle
3/8" & 1/2" spotface
- Items Used Only Occasionally & Can Be Borrowed
Nicopress sleeve tool
1 dozen 1/8" Clecos
Hotwire voltage control
The following tools are ones you make:
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 styrofoam wrapped with sandpaper.
Alot of elbow grease is saved if you replace the sandpaper often.
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 1x4 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 or Wicks - 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!
Devices which automatically ratio the correct amount of resin and hardener and dispense it with the pull of a lever are available from VariEZE distributors for approximately $130. These save time and epoxy. You can ratio the epoxy the way we did in building N7EZ and N4EZ by building the following simple balance; Cut out the 5-step instructions and glue to your balance - don’t skip steps! Follow each step exactly every time you mix epoxy.
