Jig Pattern
|
|
Cut a 12x10 cm rectangle from 3/8 inch thick balsa wood. Use the
diagram as a guide to drawing six horizontal and eleven vertical
lines on one side of the 10 x 12cm balsa wood block.
Draw the horizontal lines at the positions indicated, draw the
vertical lines 1cm apart.
The grain of the wood should be
paralell to the 12 cm edge.

Bead Wells
|
|
Carve out the bead wells indicated by the diamonds in this diagram.
The top row has nine wells and the other rows have ten wells each.
The wells need to be only deep enough to put the hole in the bead at
level of the surface of the balsa wood. Do this with
a wood carving
tool. You can make each depression with two cuts from the tool.

Second Cut
Keep your hands and other parts of your body away from the direction
you are pushing the tool so that if it slips you do not injure
yourself. If you prefer, instead of carving the bead wells,
you can
glue 1/16-inch by 10-cm strips cut from a 1/32-inch sheet of
basswood over the eleven vertical lines drawn on the
jig.
|
Dividers
|
|
Next, place dividers between the rows and at the top and bottom edges.
You can
carve
dividers from 3/8 inch thick balsa wood to a width of slightly
less
than 1 cm wide (adjust the thickness as necessary). For the
top and bottom edges, carve a divider approximately .5 cm wide.
Or, you can
use 1/8 inch x
1/8 inch
basswood strips. Place one strip on either side of each row.
If you
can find 1/4 inch
x 1/4 inch triangular sticks, they make the best
dividers when placed on top of 1/16 x 1/8 inch strips.
Attach the dividers to the jig with glue.

Options
|
|
If you want, you can add the following options
to your bead jig:
- Attach 3 - 4 mm thick "feet" under each corner of
the jig to raise it slightly from the surface of the table.
This will give you more room for the hand holding the
threading rod when you use the jig.
-
Glue a piece of 1/8 inch thick basswood 1 inch high by 12 cm long
to one
edge of the jig to keep it flush against the edge of the work surface.
This helps keep the jig steady during use but it also restricts how
you can position the jig on the table.
