66 Chapter 4 Hand Tools
2. Set a compass, dividers, or trammel points
to this distance and draw a circle.
3. Begin at any point on this circle and without
changing your setting, draw a series of arcs,
starting each arc at the place on the circle
where the preceding arc has intersected the
circle.
4. The last arc that you make should intersect
the circle at the starting point made by the
compass, dividers, or trammel points.
5. Now join all of the points with a
straightedge to form the hexagon.
Rounded Corners
Many times the corners of wood products
are rounded instead of square. These rounded
corners are arcs. To lay out rounded corners, re-
fer to Figure 4-22 and follow these steps.
1. Look at your working drawing to see what
the radius of the corner should be.
2. Mark this distance from the corner on the
side and on the end of the workpiece.
3. Holding a try square against the end and
edge, draw two lines that will intersect.
Where the lines cross is where you will
set dividers to the proper radius and
draw the arc.
Enlarging Irregular Designs
You may fi nd a project you want to build in
a book or magazine. The project plans will be
much smaller than the actual product. If there
are any irregular shapes, you will have to en-
large the plan to full size and transfer it onto your
workpiece. An example of an irregular shape is
shown in Figure 4-23. In order to transfer this
shape onto a workpiece, follow these steps.
1. Many times the original drawing is on
squared paper and there is a note, such as,
“Each square equals 1 inch.” This means
you will need to create an enlarged drawing
on grid paper that has 1″ squares.
2. Take a large piece of paper and lay out 1″
squares on it.
3. Starting at the lower left-hand corner of the
large paper and the original drawing, label
all of the horizontal lines A, B, C, D, etc., and
the vertical lines A, B, C, D, etc.
4. Look at the position of various parts of
the original drawing. Locate those same
positions on the large sheet.
Radius
Figure 4-21. Layout of a hexagon. The circle and
arcs have a radius equal to the length of one side of
the hexagon.
Figure 4-22. Rounded corners can be laid out with a
try square and dividers. They could also be laid out
with circle templates.
