IntroductionMy project is made of MDF and painted in a medium
blue, with gold accents. A mottled darker
blue fabric provides a simple background that does not compete
with the design. I used aquarts mechanism with 3/4 shaft length and
5/16 diameter shaft. The thickness of woodused can be adjusted
according to the mechanism you choose to use.
INSTRUCTIONSPrepare the work pieces by cutting them to size on
the scroll saw. Print the patterns. Apply alayer of masking tape to
the top of the work pieces. Add an extra layer of wood to
stack-cutthe star overlays so that you have extras in case any are
lost. Use temporary-bond sprayadhesive or glue stick to attach the
patterns to the tape.
Use the 1/16 bit to drill the blade entry holes. Switch to the
1/32 bit to drill the very smallopenings. Remove the burs created
by drilling the holes using a scraper blade along the grainof the
wood. Thread the No. 3 blade and make the inside cut of the clock
pattern. Do not cutthe perimeter line at this time. Cut the star
overlays.
Steam or iron your chosen fabric to remove any folds and
creases. Use sharp scissors to cutthe fabric to the required size.
Apply fabric glue to the backing work piece and spread the
glueevenly with your forefinger. Place the fabric on the backing
and smooth the fabric from thecenter towards the edges. Allow the
glue to dry. Position four short strips of masking tape onthe
corners of the fabric-covered backing and on the corresponding
positions of the clock workpiece. Use pieces of thin double-sided
tape in between the masking tape on these spots totemporarily
attach the clock work piece to the fabric-covered backing.
Thread the No. 5 blade and cut the perimeter line of the pattern
through both layers. Usecalipers to measure the shaft diameter of
your quarts mechanism. Use a punch tool to markthe center position
on the cross of the pattern and drill the shaft hole through both
layers with
the required diameter bit. I used a 5/16 bit for my project.

Carefully detach the two work pieces and remove the tape and
patterns. Lightly sand theedges of the work pieces using 320-grit
sandpaper to remove any burs. Remove all sandingdust using a
hard-bristled paintbrush.
Apply several layers of blue spray paint to the front and side
surfaces of the clock. Carefully
spray the back and side surfaces of the backing. Work in the sun
and allow each coat to drythoroughly before applying the next.
Spray some gold on the moon and two of the stars.Spray the star
overlays with gold.
Apply beads of fabric glue to the back of the clock piece.
Position the piece on top of thefabric-covered backing and either
apply clamps or place it under a heavy weight. Allow theglue to
dry.
Fit a saw tooth hanger to the back of the clock. Glue the star
hour markers on the clock withCA glue (use tweezers to pick up the
stars and position them). Fit the quarts mechanism andhands.
