Using Paper
Templates-
Hand carving the cavities out for adding inlay work into the body
or fret board of a guitar can be very time consuming and requires
special shaped scribes for removing the wood. Luckily most of us now
have the advantages of the Dremel tool which comes in quite handy.
First thing you need to think about when doing an inlay is of course
a pattern. After you have this drawn out a neat trick for attaching
it to the board itself is to use common children's washable glue,
which can be found in any office supply store and many other markets.
The advantage of this glue is that once your finished cutting against
your template you simply moisten a towel or rag with water and it
will separate and lift the paper template off of the wood leaving
no residue. Be sure before you start to make several copy's of your
template encase you need to replace a section or refer to details
which have been messed up by the bit of the Dremel.
Fine Detail
Work-
For that average wood worker the standard bit assortment that comes
with a Dremel works just fine.
If your thinking about doing finer detailed work such as intricate
inlays though, you had better think about investing in the smaller
collat. and bits which are available in 3/32" instead of the standard
1/8". If your really thrifty sometimes you can talk your dentist into
giving you his used bit's which are generally #59 course cutting heads,
but still fine for doing this kind of work. I also purchase several
different tipped bit's from Turbo Carver
to do this type of work. You should also invest in a router base for
your tool as well which will help you when cleaning out the larger
area's of your pattern.
A Tip I have just come across which helps out greatly is to get a
hold of a really cheap aquarium air pump and attach the hose pointing
down at the tip of your bit. This will blow away the shavings while
you work and save you a lot of time by not having to stop and clear
your cavities of debris.
Working
with Silver-
For those of you wanting to add that little something special to your
project and not on to tight of a budget, you might want to have a
go at using silver. Working with silver is very easy if you have the
proper tools. What you will first need is a tool called an amalgamator.
This tool simply vibrates preloaded capsules which contain a fine
bladder pack of mercury along with a mixture of copper/tin powder.
This produces the silver commonly used by dentist's world wide for
filling teeth. You can purchase both the amalgamator and the silver
capsules from Turbo Carver. I personally picked my amalgamator up
off Ebay. You will also need an artist spatula to work the silver
down into the cavities.
A Safety tip here, you will need to wear a respirator and gloves while
working with this process as it does involve working with a known
hazardous material (Mercury).
Carve out the cavity (about 2mm deep) in your project and underscore
the outside edges giving the silver something to hold on to when it
hardens. This way it won't fall out. Place a capsule into your amalgamator
and set the timer for 4 seconds which is the normal time for mixing.
Once the amalgamator has finished vibrating and mixing the chemicals
together open up the capsule and you will find a small silver ball
which has the texture and hardness of a small ball of gum. Your going
to need to work fast now by filling the cavity and leveling it out
as soon as possible since the silver will start to harden immediately,
you generally have about 2-3 minutes of quality working time using
this method. If you over fill the area you can always file and polish
it down. If the amount of silver produced by a single capsule was
not enough, leave a rough edge along the open area for the next one
to grab onto.
Quick Cavities-
Want somebody else to draw out and scribe the outline of your cavities
for you?
If your not to picky about the pattern, you will find that many engravers
have a large selection of symbols and images to choose from. Most
would be more than happy to cut the pattern out in your project for
a fair price. This can be a quick and easy solution for many people
since engravers work with a tool similar to a pentagraph which allows
them to adjust the size of the image they want to produce thus giving
them the advantage of being able to engrave it into smaller areas
such as upper fret's and still keep it in proportion with all of the
other images.
Chances are you can find an engraver in the phone book, if not look
up trophy and plaque makers.
Filling
and Attaching-
The most common adhesive used in attaching pearl and abalone in to
the cavities of an inlay is hide glue which can be purchased from
Stew Mac. No a days many people resort to using hot glues but you
may find that to brittle when it hardens depending on the location
and thickness of your inlay material.
For filling in inlays which are to deep the best product on the market
is Clear Casting Resin which can be found at almost any art or hobby
store. This is a two part product which usually takes 24 hours to
cure properly but will give you fantastic results and is easy to level
and polish.
