Things To Know When Making Clock Frets
By
Matthew Share
Some of the techniques when cutting out fret patterns have
always been the same techniques and methods used over the
years when working with longcase clocks. I find them easy
and most importantly faster when trying to make a living
repairing or building new longcase clocks.
Having cut out hundreds of fret patterns when working on new
and antique longcase clocks, the hardest part of making a
fret is getting the perfect fret shape to fit the hood.
1.
USE GREASEPROOF PAPER AND A WAX CRAYON
FOR MARKING OUT THE OUTER SHAPE.
If you are working on an antique longcase clock and the fret
is missing from the hood, the best way is the traditional
way by using greaseproof paper and a wax crayon or soft
leaded pencil.
You can lay the greaseproof paper over the area where the
old fret is missing and you can then rub the wax crayon over
the fret shape, giving you the outer edge shape of the fret
on the paper.
2.
USE AN OLD CEREAL BOX FOR THE CARD TEMPLATE.
This is just a rough pattern at this point. Now transfer the
shape of the fret onto a thin piece of card, you can use an
old cereal box or the like, then cut out the shape of the
fret. Once the card is cut to the correct fret shape it is
very important to make sure the card cut out fits tight in
the fret hole or space of the old fret you are replacing.
When you have your card template fitting correctly you now
need to make two more templates exactly the same shape and
size as your original, these are used to sandwich the veneer
you are making the new fret from, and this will give it
strength when cutting the fret out and stop any breakout of
the veneers.

GLUE THREE SHEETS OF VENEER TOGETHER FOR THE FRET THICKNESS.
The actual fret is made from sheets of veneer, normally you
can glue together three sheets of veneer using PVA glue and
a small veneer press, or two boards and a heavy weight on
top.
When the sheets of veneer are dry transfer the shape of the
card template onto the veneer ply and cut out. This is done
with a scalpel or sharp chisel and make sure the veneer fret
fits like you did with the card cut out, some times a file
is needed to make a really good fit. When this has been done
you need to glue the fret pattern to one of the card
templates, depending on what pattern you have chosen, some
times you may have to juggle the pattern around to fit in
side the fret shape.
Now you can
sandwich the veneer you are making the new fret from between
the template with the fret pattern on at the top, and a
blank card template at the bottom by taping the edges
together with masking tape.

4.
USE A SMALL BLADE AND HAVE THE FRET SAW ON LOW SPEED
TO KEEP IN CONTROL.
When
your fret is taped up and ready for cutting out you need to
drill holes in the parts of the fret that has to be cut out
and removed. These holes are for the fret saw blade to fit
through, when cutting the fret out use your finest blade and
have the fret saw on the slowest speed, this will give you
more control with the fret saw and the level of work will be
much higher. When all the fret is cut out remove the card
from around the veneered fret, give the fret a touch up with
a fine needle file and sand to finish.
5.
DON’T TAKE FOR GRANTED BOTH FRET SHAPES ARE THE SAME.
If
you are restoring an antique longcase clock and both sets of
frets are missing from the hood, for example a swan neck
hooded clock, you will probably have to make both the fret
shapes separately as most antique clocks may have already
been restored or altered over the years or with the passage
of time they may suffer from twisting or shrinkage and most
probably be different, so don’t take it for granted they are
both the same.
When building
new longcase clocks you know that both frets will be
mirrored so you can cut both frets at the same time.
