Power tools are very important to make our work accurate and productive.
Most of wood materials used for speaker enclosure or horn speakers are
hard to cut or to form by hand tools. Therefore, electric powered tools
are imperative for these works.
First, a circular saws is very useful for strait cutting hard wood such
as laminated lumbers or plywoods. Various kind of blades for circular saws
are sold in DIY shop. We have to choose suitable blades for the materials
we use. On top of a circular saw, a table saw is "nice to have"
tool. We can reproduce the same size of wood pieces with very productive
manner. A table saw cuts wood materials very sharply because of higher
RPM (revolution per minutes) of drive motor. Also we can cut out materials
with any angle with any size very accurately. There are many kinds of blades
are sold, too.
A electric drill is widely used as one of a most convenient tools. It has
a lot of accessaries including drill bits, various diameter of hole saws,
screw driver bits, rotary sander attachment and etc. Most of visitors of
this Web site already have this tool(s). I recommend to have one more drill,
then the work efficiency is improved dramatically. A cord-less drill is
also convenient as a screw driver. If you have a drill press, this will
give us a chance to make holes with more accurate angles and depth.
If you are intending to make a horn speaker, 1in (2.54cm) or 2in (5cm) hole saw bit (s) is (are) needed depending upon horn driver size. The blade itself can be used for a circular saw and for a table saw, however, usually the size of table saw blade is much larger.
The third important tool is a jig saw. This will be used to make lager
size of holes such as loudspeaker driver mounting holes or vent holes or
others. Jig saw blade has many kinds depending upon purposes. However,
if you allow to provide a router, you can do better work to make much more
fine and delicate holes. You can also decorate corners of a enclosure by
using variety of router bits.
A plane is common woodworking tool. However, it is not so often used to
build a enclosure, but it is mandatory needed to build horn speakers to
make convex surfaces.
Other useful and powerful tool is a rotary sander. A rotary sander is to
finish surface very effectively. There are various kinds of sanding disks
from fine to coarse grades available.
Those are major electric power tools when we use for speaker crafting.
When we use power tools, the most important thing to be considered is safety operations. Since power tools is very powerful, damage is also big. We have to strictly follow safety instructions of each tool.
Second important thing to do good work is that we have to keep the blade sharp. Dull blade will not yield good result including safety. |
