grains of the wood will be rather rough to the touch, and will require some extra
sanding to produce a smooth even surface. You may have to use a 150 grit in
the beginning on the end grains. Sanding is best done outdoors. Wear a
disposable paper dust mask while sanding.
Finishing:
Your local hardware store stocks small cans of woodworker stains.
Either a walnut or mahogany wood stain finish is a good choice. Both oil-based
and water-based stains are available. We suggest using a water-based stain for
this project—it is easier to work with and easier to clean up afterwards. You
will need a clean cloth, or
staining cloth
, to apply the stain. Follow the
manufacturer’s directions very carefully, and read the safety information on the
label. Use disposable latex gloves when handling stain. If you’re too young to
safely work with wood stains, ask an adult for assistance with this portion of the
project.
Always handle any chemicals with great care!
Important Note:
Once the stain is dry to the touch, the assembly work may
begin. Before attaching the tuning capacitor with the double-sided adhesive
tape, the board should be allowed to dry for a few days. This will allow the stain
to fully
cure,
or dry, so it does not interfere with the tape adhesive.
BEFORE YOU START BUILDING
Your work area:
Use a good workbench with good lighting so you can see
what you are doing. At times we will need to set items aside to allow glue to
dry; or you will need to stop working on your project for other activities. Your
work area should be in a place where your project does not interfere with others.
Keep your work area clean and free of clutter. Kit parts should be kept in the
box until you need to use them. When you are finished for the day, return the
tools to their proper place. Put unused kit parts back in the box so you will not
lose them. If you are old enough to use glues and wood stains, you may have
younger brothers and sisters who aren’t! Keep chemicals out of the reach of
younger children.
Following directions:
Kits are built in “steps”. These steps follow a logical
order, that means following the instructions will make your kit building
experience easier and ensures that your project will work
first time
when
finished.
You will notice a check box
!
as each instruction gives you a simple task, or
direction, to follow. When the task is finished, make a small check mark in the
box to show that part has been completed. This will allow you to keep track of
where you left off when returning from a break.
For example, a direction may read:
