An
interesting aspect as to the differences in the
cutting methods used by the marquetarians in the UK and those
marquetarians on the "other side of the pond" in the USA has been brought
to light recently from within the friendly environs of our Redbridge Marquetry Group.
The cause of this interesting debate and the ensuing observations was due
to the introduction
to our group of a review copy of Silas Kopf's excellent "The Master
Techniques of Marquetry" DVD. This DVD, (which was produced in the USA) has
been circulating among the members of the Redbridge Marquetry Group
recently and it
has inevitably brought to our attention the subject of the differences in thickness
between the USA sourced veneers and the veneers we use here in the UK.
This perceived difference is that the USA veneers are twice the thickness
of the UK veneers (1/32 or 1/28th of an inch USA - 1/64th of an inch UK).
That difference in the thickness of the veneer stocks obviously obliges us
both to
use different cutting methods due, primarily, to the added difficulty of
attempting to "blade" cut veneers at 1/28th of an inch thick
that are
stinkers to cut when they are only 1/64th thick!, I'm sure you'll appreciate
the problems involved.
To illustrate those different
cutting methods we are including several clips taken directly from Silas's DVD along with
some photos of our RMG members hard at work with their 1/64th inch thick
veneers and using their trusty scalpel blades!

Silas uses a "frame" saw with a foot
operated
clamp system to hold the work in place |
In this first "clip" you can see Silas using a standard "frame" style of saw
and blade. It's actually much the same type of tool as you will see our
Alf Murtell using in his piercing saw tutorial. As
Silas is a furniture maker he generally uses packs of veneers, (often up to ten
veneers in the pack) in order to ensure consistency of design when
multiple marquetry inserts depicting the same design are required for a
piece of furniture.
A very important tool that's being used by Silas in this
photo is a foot
operated clamp, of which you can see a detail below. |
| Silas operates the clamping
system by opening and closing the clamp by just pulling the foot bar
towards or away from him. This method leaves both
hands free to use the frame saw without restriction and to manipulate the
veneer pack as required.
The clamp system Silas is using is obviously a large
piece of equipment and would necessitate a decently sized work shop. If
you are limited with your space, you could use the arrangements that you
will see our Alf using in his piercing saw tutorials. |

This is a parallel cutting saw
arrangement that
will cut at 90 degrees to the veneer pack |
The saw you see Silas using in
this photo runs on an arrangement of "slider" bars that ensure that the
saw blade will cut the veneer pack (of perhaps ten veneers or more) at an
exact 90 degrees to the face of the pack. This will ensure consistency of
the cut, right through from the veneer at the front of the pack, on to the veneer at the rear
of the pack. When the cut pieces are assembled in
the projected design there will be a uniformity achieved with this cutting method
that would not really be possible with blade cutting. So, for a repetitive
pattern or design needed for furniture decoration, this cutting
arrangement could not be bettered (unless you are using a laser cutter of
course!) |
| As you will see in the picture
on the right, the standard method of veneer cutting in the UK is to use
the blade or scalpel method. This style of cutting
works well enough with our 1/64th of an inch thick veneers, but with the
USA veneers at 1/28th & 1/32nd of an inch thickness, you will find that
the blade would be difficult to control properly.
The thicker veneers will "catch" the blade of your
scalpel so much that you will find yourself yearning for the ease that saw
cutting would promise you. |

This photo shows a picture
being cut with a scalpel. A steel rule is being
used for achieving a clean straight cut across the border mitre.
Because 1/64th inch thick veneers are used, a certain
amount of spontaneity is available to the marquetarian that is only really
possible with the freedom of blade cutting. With saw cutting the design
has to be drawn on to the veneer so that you have a guide line for the saw
blade to follow.
Scalpel cutting does allow the "spear point" arrangement
which is used for "blending" one veneer into another. Saw cutting would
rather preclude this method. |
| In this photo on the right you
can see Silas using the "parallel" saw on a veneer pack.
This saw uses the same clamp arrangement that we saw Silas
using with his hand held frame saw.
On the next page you will see some examples of the
veneer packs that Silas assembles for use with this parallel cutting saw.
You will also see some of the completed marquetry
designs - and - especially for my own personal envy - that wonderful old
Leviathan of a press that Silas uses. It's a superb piece of heavy
engineering! |
