Woodshop Dust
Control - 2nd Edition
A Complete Guide to Setting Up Your Own Workshop
Dust Control System - Revised and Updated
Second
Edition By Sandor Nagyszalanczy
Complete Overview of Solutions to Workshop Dust
Control.
Wood chips and sawdust in the
woodshop are not just a nuisance -- they can also
present a significant health hazard. But the good
news is that this completely revised, color edition
of Woodshop Dust Control provides all the
information you need to protect yourself from wood
dust.
Sandor Nagyszalanczy presents
a complete overview of solutions to woodshop dust
problems -- including up-to-date information on the
latest products. Sandor covers everything from
simple, inexpensive shop vacuums and portable
collectors to full-blown central dust collection
systems with cyclic pre-separators.
You'll learn how to protect
yourself from respirable wood dust using masks,
respirators, and air-filtration devices. You'll also
discover ways to control dust and capture the
mountains of sawdust produced by portable power
tools and stationary machines. When its helpful,
Sandor uses charts and graphs to illustrate the
information. With the advice in this book, you'll
get practical information on designing, building and
installing a system that's right for your shop.
"Takes a comprehensive
look at dust control issues and solutions for
small-shop woodworkers. A thorough guide to matching
a shops needs to available solutions."

Introduction:
Up until just a few years ago,
the primary means of dust collection in most
woodshops was a simple broom and dustpan. But
21st-century woodworkers are much more aware of the
impact of wood dust on their respiratory health.
They are also aware of the fire danger that sawdust
poses to their shops -- and the homes that are often
attached to them. Hence, woodshop dust control has
become a hot topic, and the devices and strategies
used to collect chips or filter dust now receive
almost as much attention in the woodworking press as
the latest and greatest machines, portable power
tools, and shop gadgets.
Since Woodshop Dust Control
was first published seven years ago, hardly a week
goes by when I don't receive an e-mail query or
telephone plea from a puzzled reader: Can I design a
ductwork system using my computer? Should I replace
the bags in my portable chip collector with advanced
filter media? Are there affordable ways I can
automatically control my central system? Is there
some new way I can ground my plastic ductwork? Which
disposable dust mask is best for me, according to
the new guidelines of the National Institute for
Occupational Safety and Health (NIOSH)? Can I make
the power sanding of wood parts a cleaner task?
Keeping up on the latest collection equipment and
methods is essential to providing the best answers
to such questions.
Fortunately, technology and
product design have kept pace with the current trend
to make dust collection as much a standard part of a
woodshop as electricity and lighting. Lots of
noteworthy innovations and improvements in dust
equipment and accessories have come to market in the
last seven years, including: better filters for dust
and chip collectors, disposable bags for portable
power tools, advanced electronic systems that make
central collection systems easier to control,
air-filtration devices that are more convenient to
use, affordable downdraft tables to capture fine
dust while sanding, and easier-to-use shop vacuums
with better fine-particle filtration. One of the
goals of the new and updated version of this book is
to acquaint you with the complete range of
dust-control devices and methods available to outfit
your small (or not-so-small) woodworking shop.
Some things about dust control
haven't changed since the earliest days of
woodworking. Sawdust is still a woodshop nuisance: a
messy by-product that's hard to avoid. Our machines
churn out great heaps of chips and shavings that
combust all too readily. They also throw a ton of
fine wood dust into the air, which, as medical
studies continue to reveal, can pose a significant
health hazard. Do we really need more to convince us
that capturing and controlling woodshop dust is an
essential duty?
Probably the hardest part of
dealing with dust is knowing which devices and
methods to choose from among the extensive
assortment of collection, filtration, and
ventilation devices currently available. One class
of devices, including shop vacuums and central
collectors, is designed to capture dust at its
source -- at a woodworking machine, a sanding table,
or a workstation where portable power tools are
used. These devices provide the most direct and
efficient means of dust control since the majority
of chips and dust are captured and collected before
they can escape. Airborne dust can be abated by
several different secondary control methods,
including ventilation and air filtration or by
wearable protection devices such as disposable
masks, replaceable-cartridge respirators, and
powered air-purifying respirators.
Unfortunately, buying the
right respirator to protect your lungs or picking a
collector powerful enough to handle your shop's
sawdust output isn't as straightforward as the
process of buying a handplane or table saw. If
you've browsed a woodworking supply catalog or
website lately, you've likely been confronted by a
confusing array of information about particle size,
filtration efficiency, airflow and ductwork sizing,
cubic-feet-per-minute (cfm) and static-pressure
ratings, etc. This kind of technical data is usually
more befuddling than helpful. A troubling result is
that many woodworkers end up with equipment that
provides only a poor or partial solution to their
dust problems.
This updated version of my
book presents all the latest information you'll need
to choose and implement dust control in your shop
with a minimum of head scratching. Everything you
need to know is explained in layperson's terms that
you don't need an engineering degree to understand.
Better still, there are lots of suggestions for how
to achieve your dust-control goals without breaking
your bank account.
This book's chapters progress
from simple and inexpensive dust-control measures,
such as wearing a dust mask and ventilating the
shop, to more complex and expensive means of
capturing and filtering dust, from shop vacuums and
portable collectors on up to full central collection
systems. Because installing a complete central
system is an extensive undertaking, the last four
chapters are devoted to all the necessary steps,
from choosing a collector and designing the
ductwork, to hooking up machines, to fine tuning the
system for best performance.
Whichever dust-control
measures you choose, you'll end up with a shop
that's a cleaner and healthier place to work. After
you take the plunge, I'm sure you'll never let a
little thing like sawdust get in the way of your
enjoyment of woodworking again.
