Hints
and Tips
The following is a
selection of techniques or tricks that I have found useful. Feel free to contact
me if you would like to share your tips, and I will update the page
periodically.
Blind Nailing.
This is a neat trick stolen from Melvyn Hiscock to
stop glued parts sliding out of true as the clamps are tightened on them. Simply
drive a couple of small veneer pins into a part of the wood which will either be
removed as waste, or will be otherwise out of contact with saw blades and
routers, then cut off their heads very close to the surface of the wood. Line up the
piece to be joined and press it into place, causing the pins to push into its
surface, then remove. When glue has been spread (watch the fingers with those pins!) and the
parts are reunited these depressions will allow you to locate the pieces
accurately and prevent movement when clamping.
Danish
Oiling.
I love Danish Oil as a wood finish. As a teacher I
find that it allows students to produce a professional quality finish with ease,
and as a woodworker and guitarist it provides a beautiful finish to play an
instrument, as well as being easy to maintain and 100% natural. Unlike
‘plastic’ finishes it is also fully and invisibly repairable.
As with any finish the key is in meticulous
preparation. I always sand flat surfaces with a cork block, and run through the
full range of papers from around 120, through to 400. I then burnish the surface
with 00000 grade steel wool to remove any finger marks. I wash my hands
regularly to prevent these.
I always oil away from the workshop to keep clear
from dust. The job is usually done in the spare bedroom where movement is at a
minimum. I hang bodies and necks from a portable clothes rail so that I can
access all parts at once and to avoid unoiled patches. Wood screws are inserted
into the lower strap button hole on the body, which is hung from one of the neck holes, to help
hold it when applying the oil.
I use a section of an old 100% cotton t-shirt to
apply the oil straight from the tin (the opening of which must be kept free from stickiness). I
apply two coats a day (early morning and evening), and work in the direction of
the grain, ensuring the oil is worked in well, applying enough to just wet the
surface of the wood (bright lights and windows are useful to check application).
Oiling needs to be done fairly quickly as it soon goes ‘tacky’. When I have
oiled a whole body or neck I lightly run over it again with a damp part of the
cloth to even out any streaks.
I usually apply four or five coats, and between
each I lightly rub 00000 steel wool over the surface, going with the grain, to
remove any dust which may have settled.
When the last coat has fully hardened wax can be
applied, in my case Renaissance micro-crystalline.
Sellotape
double-sided tape
This is, in my mind, one of the guitar builders’
essentials. It is available in several widths and is amazingly sticky, yet
leaves minimal residue when removed. I use it for holding most templates in
place, and for holding fingerboards onto MDF sheets when sanding them (just be
careful when inserting that chisel to remove them!).
