MARQUETRY REPORT NUMBER 1 |
By
Roy Murton.
Artistic skill is not a pre-requisite of Marquetry. At school
almost all will have traced maps or something and now we will try to show
you that you can adapt that tracing skill to create fine pictures in wood
using first a pencil and then a craft knife. I feel sure that many people
are put off by the name Marquetry because they confuse it with marketing,
thinking we are trying to sell them something when in fact we are only
trying to teach them a skill that will absorb them and amaze their families.
We are fortunate to have recruited four new members during
our autumn/fall term in 2004.They are Eddie Grigg, Stan Adelman, John Hallet,
and Ron Smith.
All but Ron Smith were completely new to Marquetry. Ron had
already made one small picture from a kit. I explained to them that there
was no right or wrong way to do marquetry but the window method was the way
we as a group worked and I would show them the method that we use to create
our pictures.
Eddie, John, and Stan were complete novices so I took a small
piece of Sycamore veneer for each and drew a square a rectangle, a triangle,
and a circle on it to demonstrate the difference in cutting with the grain
of the veneer as opposed to cutting across it.
I explained that as the veneer still contained a small amount
of moisture it was necessary to lubricate the scalpel blade periodically
using white candle wax. This prevents suction which could grab at a bare
blade and possibly split the veneer when the blade was withdrawn. I
emphasise white wax because using coloured wax might mark light coloured
veneer and have a detrimental effect on the finished work.

We supplied each of them with a plastic craft knife into
which I inserted a number eleven scalpel blade and as these blades are
exceptionally sharp it is always advisable to use pliers when changing
blades.
I changed the locking screws of the plastic handles to suit their right
handed grip before retightening allowing about one and a half
centimetres of the blade to protrude from the end of the knife.
This stops the blade bending when cutting and eliminates
breakages to the tip.
|
|
I changed the locking screws to the opposite way that they
are supplied because the way the screw protrudes can cause blisters on the
inside of the second finger and can be quite “off putting “ to a beginner.
The knife is held in much the same way as a pencil and that the heel of the
hand should rest comfortably on the cutting surface. The knife should be
held at a sixty degree cutting angle to the veneer and the blade should be
square to the surface.
Each beginner was given a cutting board. The blade is used as
a piercing tool using only the very tip of the blade pushing downwards. I
then advised each of them to hold the veneer on the cutting boards using
their thumb and first finger of their left hand so that both digits were
about three centimetres away on either side of where they were working so
that even if their blade was affected by suction it could be easily freed
without breaking the veneer.
With the piercing method it is possible to cut very
accurately whereas using the knife as a cutting tool in the normal way the
blade could follow the grain rather than the cutting line.
As they were all right handed I told them to place the tip of
their knife on the line at the bottom right hand corner of the square and
push the blade downwards into and through the veneer which made a small sit
one or two millimetres long. They then put their blades slightly further
along the line and pushed the tip through the veneer again.
By starting from the bottom right of the shape they would
always be able to see the line that they were cutting along otherwise their
own hand would have obscured the line they were trying to follow. When they
had reached the top of the first line it is necessary to turn the wood in
order to pierce along the next line. It is always best to try to keep the
hand in one position and move the wood rather than twisting the wrist. By
doing this there is more control over the knife. This process was continued
until the shape had been cut out and the shape should fall out leaving
what we call “The Window”. If it doesn’t fear not! it just means that your
piercing’s were in some places too far apart and can easily rectify by re-
piercing .
A contrasting piece of veneer was placed behind the window
that we had cut positioning the grain in the direction required. This window
was to become our template. This was secured by two or three small pieces of
white veneer tape stuck in such a position as to hold both pieces of veneer
together.
Using the window as the template our
beginners were shown that it was essential to put the blade of the knife
pressing on the inner edge of the window, at the bottom right hand corner
and proceeding to carry out the same piercing action as with the first,
turning the veneer in exactly the same manner as before.
I have found that this starting at the bottom right hand side
is better for right handed people and that left “hander’s” should start from
the left hand bottom corner
Once a shape has been pierced around it should always be held
up to the light to make sure there are no unpierced areas If there are re
pierce them. Do not be tempted to force the piece out as you will invariably
split the veneer which will be very frustrating and could lead to your not
finishing what could otherwise be a “masterpiece”.
Once the second piece of veneer is freed from the veneer
around it should ‘pop’ into the window and you can then rub a thin film of
P.V.A. glue over the top forcing it into the cracks at the edge. Do not use
too much glue as being water based it will cause the wood to swell.
It is then necessary to smooth the pieces down. For this I
use a teaspoon and press down with the bowl of the spoon. This application
of the glue also tends to enlarge the veneer to a very small degree and
helps to fill any very small gaps that may be left. The joined pieces are
then once again held up to the light to see if any light can be seen which
would show how closely or not the piercing has been made to the template. I
tell them that if there are some gaps don’t worry, with marquetry you can
only get better and you can always re –cut that piece anyway.
At this point I always say “”Welcome to Marquetry” because
what they have just done is to have learnt the basic of all Marquetry and
all our other members work the same way.
You should not attempt to work on the shape immediately next
door. So in this case I told them to work on the triangles next, which they
did, using the same method. When working on a shape with sharp points, it is
“oh, so easy” to lose the “points” when you are cutting the piece to be
inserted. So to prevent this I advised that they stick veneer tape over the
surface of the piece they would use as the insert and they should cut
through the tape as well as the veneer. This tends to hold the veneer and
avoids breakages to the points. Alternatively the veneer to be inserted can
be smeared with P.V.A. glue. This works nearly as well as the tape method
but takes a little longer as one has to allow the glue to dry before it can
be used.
|
With very complicated shapes it is sometimes necessary to
stick paper veneer tape on both sides of the insert veneer and to cut
through both pieces of tape at the same time.
The tape can be removed by
damping and scraping with a discarded blade.
The rest of the shapes were then cut out in the same way apart from the
circle.
The circle is different in that the hand is kept in the
same sixty degree angle to the cutting board but the cutting should be
the same as cutting a straight line so every time the veneer is pierced
the veneer must be moved!! .
Having cut out the circular window the veneer
should have a small line drawn out from its edge and a similar line
touching should be drawn in pencil on the piece to be used as the insert
so that when the insert has been removed it can be exactly lined up in
the correct place by matching the position of the two lines
|

After each shape was finished they held it up to the light to
see how well or badly they had worked. In fact their efforts were very good
indeed especially as they had never experienced marquetry before.
Eddie, Stan and John joined us in our autumn/fall term of
2004. Eddie was introduced to us by one of our oldest members Horrie Pedder.
John had seen one of our advertisements in the local library and Stan had
seen our advertisement in one of the local free newspapers. Ron is an old
friend of Eddies and he came to us a little later in the term but he had
already made a kit picture and had made quite a good job of it except that
when he glued the picture to the base board it had twisted and so was out of
square, not by much but he was rather upset about it but was much happier
when one of our other members took it home and squared it up by cutting the
base board with a band saw.
Making a first picture from a kit using written instructions
is not easy, seeing someone actually doing what they have been reading about
is so much easier to understand.
Having mastered the basics we gave them all the opportunity
to find a line drawing from the design books in our club library. We try to
get beginners to find a relatively easy picture that without too much effort
can be completed within five to six weeks, because anything too demanding at
this stage would possibly put them off such an interesting and absorbing
hobby.
Select a picture that appeals to you. It will give you the
impetus to carry on because we would not want you to find it difficult and
then want to give up. People often say that they can’t draw but what they
mean is that they have never been taught correctly. What is most important
is that they have never been taught to observe. They
have never been taught to see what they are looking at so I get people to
look at their proposed pictures and SEE what is there and reproduce in wood
something as near as possible to what is really in front of them.

An example of what I mean is if one is copying a picture
of a ship under full sail there is obviously a wind blowing the ship
along, therefore the water on which it is sailing could not possibly
show a mirror image reflection of the ship.
The water should be represented by a veneer which
displays plenty of the grain “movement” this will mean you would only
see a distorted reflection of the ship if any at all.
The only time you will see a mirror image reflection is
on still water. Even slight movement in water will give a slightly
distorted reflection.
Look closely at your picture and interpret what you see.
Eddie and Ron both chose pictures of boats and we spent
quite a while selecting suitable back ground veneers for their new work.
Both line drawings showed boats under sail so it was
necessary to select veneer that showed “movement” in the grain and the
grain was used to show movement horizontally across the picture. |
John had selected the stylised picture of flying swallows.
Stan felt that he needed more practice before starting a picture.
The next stage for making a picture is to trace the outline
drawing using tracing paper. Stick the tracing paper by the top edge to the
line drawing with sticky tape. Using a fairly sharp pencil, (or a ballpoint
pen), trace over the line drawing. Once completed decide whether or not you
want to work on the front of the picture or on the back which would result
in a finished picture the reverse of the original. This means that if for
example a ship on the line drawing was facing east, if the work was to be
done from the back the resultant picture would have the ship facing west.
Some people prefer to work in reverse so that any grease
residue stays on the reverse leaving the front clean. I however always work
from the front because an ideal grain effect for the front of my picture
will not necessarily reproduce itself on the rear. Also by working from the
front I can see how my picture will look when finished.
Eddie and Ron had both chosen pictures which had a sky and
water so it was necessary for both of them to get two pieces of veneer one
to resemble sky and one to resemble water to prepare the waster. Or
background veneer.
Having made the selections they glued the respective edges
together and then joined the two and this became their horizons. We also
stuck veneer tape on the back of the join just to hold the two pieces
together until they were dry.
Having decided which way they wanted to work, the tracing was
detached from the line drawing and attached to the selected background
veneer using the same method as before. It is also good practice at this
stage to fix tape along the end grain of the veneer to stop it splitting due
to rough handling. Having done this, place a piece of black carbon paper
black side down between the tracing paper and the background veneer and
proceed to trace the outline and the borders onto the background veneer.
Always use black carbon paper because blue carbon tends to “bleed” and the
resultant capillary action on light coloured veneer can be disastrous.
Having traced our outline onto the background veneer (which,
incidentally we call “the waster”) we can commence to work on our picture.
If one wishes to work on the back of their picture it is necessary to decide
which side of their traced line they are going to use as a guide line. This
may seem unimportant but believe me it is. Although this line is only very
thin it can cause small slivers of light coloured veneer to be left
unnoticed until you are ready to polish your picture.

The rigging must be in proportion to the rest of the
picture.
One way of ensuring this as a beginner is to place two
scalpel blades side by side in a plastic craft knife and wrap tape
around both to within about two millimetres from the tip.
This tape stops the blades parting when cutting and
ensures evenness along the length of veneer being cut. Alternatively
fine lines can be cut using a straight edge but for a beginner it is
more difficult. This is the only time the blades are used as cutting
instruments.
Having used the twin bladed knife to cut the hole for the
rigging line it is now necessary to cut the piece of veneer for the
rigging itself.
We measured the length of veneer strip we require and
using the twin bladed knife cut a strip of either black or dark brown
veneer of the appropriate length. At this moment it will not fit the
hole [size for size does not fit] so we turn the insert strip on its
side and press a spoon along its length to squeeze it thinner.
We now put a small amount of glue in the hole we have cut
and using a pair of tweezers push the thinned down strip in the hole
running the spoon over to make sure it is flat. |

This is only one method of “fine lining” but it is effective.
When starting a picture there is no right or wrong place to
start but most people find that working from the background and coming
forward easier.
Sticking the sails into the windows, Eddie & Ron found
this to be
a bit difficult. Large pieces should be glued along the edge in stages.
Gluing large pieces in one go makes the veneer buckle and difficult to
control, so stick a little at a time.
Eddie proceeded quite well and only needed a little guidance
but Ron had problems with the mast of his boat. Although he had pierced as I
had said, the veneer he was using kept breaking up and he was getting a bit
frustrated. I told him to try again using the same type of veneer but
covering the back and front with veneer tape and re-cut it. This, he did. I
then told him to put some glue where the mast was to go then turn over both
pieces of veneer and run the end of his pencil or plastic knife handle
pushing the mast into its window. Having done so, he removed the back
veneer, turned his picture the right way up and smoothed with the back of a
spoon and the mast was inserted. He then removed the paper remaining on the
veneer by moistening and scraping.
As these tutorials are happening in more or less real time
(give or take the time it takes to write it up for the web site) you will be
following the progress of a group of new marquetarians up to them actually
reaching the levels of competition standard.
If you are new to the art of marquetry, you should find these progress
reports very useful for you to judge your own progress from, in fact you
could actually use these reports to learn the art of marquetry from basics
to advanced in parallel with our beginners. In subsequent reports we shall
include photo's of our beginner's marquetry work for you to study.
As you will
have realised,
this beginner's report from Roy has (of
necessity) been rather a long missive because it is the first, and the
introductory, one. With the next reports we will be including some
photographs of our beginner's progress on their work.
If you find this report rather over-long to read on-screen, you may prefer
to "right click" the report and print it out by selecting "print" from the
sub-menu that appears. Many people find a printed version of a long piece
easier to read from a "page" rather than a screen.
