This month we have a 'Down to Earth Woodworker' classic article, that might be useful for many
of us as spring cleaning season has arrived. Stay tuned next month for a NEW column from Steven
Johnson, the Down to Earth Woodworker!
5S Your Workshop for Efficiency, Comfort, Safety, and Fun
My friend Donald and I could not be more different. He, a retired manufacturing manager, MBA, and
expert in "Lean" manufacturing, now teaching statistics at college, and me, your crusty and dusty
reporter, content to scrape (and saw, and sand) by in the relative obscurity of my retirement and
occasionally jot down a few lines about my experiences. We spend hours discussing politics, current
events, and world economic theory, but not once had I visited his classroom, and not once had he
ventured into my workshop — until recently.
On a bet (that I lost) I had to buy Donald a complicated coffee drink at the trendy college campus
coffee shop, and as a favor, my professorial friend helped me lift the motor assembly of a new drill
press onto its support column.
I had very little to say (and certainly nothing profound) when I visited his classroom, but after
eyeing my shop for a few moments he proclaimed, "Without knowing it, you have perfectly 5S'd your
shop." Days later I realized that it was a backhanded compliment at best, and also realized after
some research, that he was, as usual, correct.
The 5S Program is a component of Lean Manufacturing, and is intended to help produce higher
efficiency and quality and to reduce waste. The origins are a bit murky, some claiming that the
Japanese learned it from Henry Ford and Frederick Taylor (author of Scientific Management, 1911) and
that 5S is a direct outgrowth of Ford's CANDO program, while others say that 5S is a result of the
pioneering work that Sakichi Toyoda, the founder of Toyota did in conjunction with his son and his
chief engineer. Regardless the history, this sound and widely emulated program is based on five
Japanese words, all beginning with "S".
The five Japanese (or more correctly, Nippongo) words have been transliterated and translated into
English. They are, Seiri (sort), Seiton (straighten), Seiso (shine), Seiketsu (standardize), and
Shitsuke (sustain). Implementing 5S in your shop, whether you are a hobbyist or pro, will make your
shop time more enjoyable and more productive. You will experience less frustration, you will work
more safely, and the chances are pretty good that the work you turn out will be of higher quality.
You will also gain space, as organization is a key ingredient of any 5S program.
A 5S program does not require you to strip your shop to the walls and start over. It works with your
existing layout, and instead concentrates on cleaning up and organizing. Unused tools, equipment,
and supplies are removed. Pertinent tools and supplies are organized into logical "work groups" or
"kits" and are labeled or even color-coded to provide an easy visual reference. Methods are
implemented to standardize certain tasks and the process itself, and then systems are put in place
to maintain the new order and achieve repeatable results.
Sort
The first step in the process, Seiri, has been Americanized as "sort" and is a pretty accurate
translation of this critical component. In addition to being woodworkers, we are all, to some
degree, tool collectors. The Sort phase of 5S'ing your shop is to critically examine your
collection of tools and remove those that are not used.
The advantages are multifold. Since upgrading to a fine quality jack plane, the old bargain plane
that I bought years ago at a home center has been nothing more than a non-powered dust collector.
The few dollars it sold for on eBay went into my "stash" for future tool purchases and the newly
acquired shelf space went to a tool used much more frequently, but that had formerly been stored
inside a cabinet.
This experience was an epiphany of sorts. Instead of groping inside a cabinet for a tool I use
often, it is now right on the shelf where I do most of my work. A tool I never used is no longer
cluttering my workspace, and I freed up a couple of dollars in the process. Seiri – I could learn
to love the language!
Take a few moments in your shop and think through the "sort," or Seiri, phase of 5S. Are there
tools you never use? Or are there tools you use so infrequently that perhaps storing them somewhere
besides in your shop would make sense? That collection of nuts, bolts, and assorted hardware you
are hoarding has needed sorting and organizing for years. Do you really need that one hinge without
its matching half? Do you really need that coffee can of bent nails (admit it, I know you have
one)? Chances are, there are three, five, or ten common fasteners you use 95% of the time, and
everything else is just eating up space and gathering dust. At the current cost of scrap metal, 20
or 30 pounds of unused hardware will not make you rich, but it will pay for the gas to get it to the
recycling center and the space you gain will make you more efficient.
For me, the sort phase is a continual process. I force myself to seriously ask the question, "Will
I ever use this 5/8" X 3/4" X 4" piece of cherry, or would I be better off using it as kindling in the
fireplace? I now keep a box close to the door, and small cut-offs go directly into this "tinder
box" instead of my scrap bin. Space gained, clutter eliminated, efficiency improved!

Set in Order
Seiton, straighten, or "set in order" is the next step in 5S'ing your workshop. Ben Franklin said
"A place for everything and everything in its place," but for his adage to hold true, he must have
exercised Seiri first. Until you sort and dispose of unused tools and materials, your "place for
everything" will consume your shop and there will be no room to have "everything in its place."
After you have gotten rid of everything you do not use, it is then much easier to "set in order"
what is left. If you do layout work at your workbench, all your layout tools should be close at
hand. Clamps close to your assembly table, drill bits by the drill press, and push blocks by the
table saw make sense, but few are diligent about purposefully rearranging things to achieve these
logical goals. In the middle of a glue-up that I had rehearsed and tested, I discovered I needed a
couple more clamps. The trip to the other side of my small shop did not take a lot of time, but it
was frustrating and added to the stress of an already complicated glue-up. A little rearranging
solved the problem forever.
Straightening, or "setting in order" should include labeling. Yes, I know, you are the only person
in your shop and you remember where everything is – sure! And I remember what double mocha latte
half-caf nutmeg-sprinkled thing Donald ordered at the coffee shop! Ask yourself honestly, "How much
time have I wasted in the last year looking for something?" A Brother P-Touch labeling machine is
one of the best "shop" investments I have ever made. With clear, white, or yellow label tape in a
variety of sizes, you can make labels for everything, and months or years from now, those labels
will be as clear and legible as they were the day you made them.
There is certainly no need to label everything, but "hidden" storage, like cabinets, drawers, bins,
and boxes should always have labels. You may also want to label certain tools that (only) fit
certain machines. For example, I would not think of labeling every Allen wrench, but the Allen
wrench that is needed to adjust my router table fence is labeled, and it is stored in the same
drawer with my router collet wrenches. This is the essence of "setting in order." Label items that
are used often and that might be easily confused with other similar items, then put these items in
proximity to where they are most used.
Cabinet doors should be labeled with their contents.
Wine boxes make excellent storage for short cut-offs, but they should be labeled to save time
The Seiton, or straighten phase of making your shop more efficient, comfortable, and productive need
not be done all at once. Like all of 5S, think of Seiton as ongoing, continual improvement. If you
notice that you are consistently using a certain chisel when fitting mortises and tenons, keep that
chisel stored close at hand. In some circumstances, I have even bought a duplicate tool, simply
because I was constantly using that tool at two different places in my shop, and it was never in the
place where I was working. The few extra dollars for a duplicate tool has saved me time, time and
again.
Shine
|
Resisting the temptation to mount my editorial soapbox, I will concede to one indulgence, and write
that Seiso, the "shine" portion of the 5S philosophy, is my favorite. After sorting through tools
and materials, disposing of what is not needed, and then straightening and organizing what is left,
a good thorough cleaning, and daily diligent upkeep, will make your shop safer, more pleasant, and
more efficient.
A while back, in another publication, I read a reader-submitted tip for installing a rare earth
magnet in a dustpan to catch errant hardware, and in another publication saw a similar suggestion
for using a magnet to separate hardware from the airflow of a dust collector. I laughed at the
inglorious tip, wondering how hardware got on the floor in the first place, and why the woodworker
would not simply pause and pick up the screw or nail when it fell. I then realized, like in so many
shops and shop pictures that I see, the writer's shop was probably covered in dust, shavings, and
other detritus, making it impossible to find a dropped nail. In some shop pictures I have seen, you
couldn't find a dropped router!
I do not own the best dust collection system (saving my scrap metal money for a new one!) but I
suspect that even with the best, some stray chips will still get away. Like gassing up our
vehicles, no matter how much we shake the hose, tap the nozzle, and keep our fingers crossed, some
gas always drips out onto our newly washed and waxed paint.
My jointer "spits" some shavings out the side, and there is always a little pile underneath the
machine when I move it. The planer has very efficient chip/dust collection, but chips still escape
the whirlwind and settle on the floor. The same is true for every other power tool, and the pile of
shavings at my feet after a good workout hand planing a tabletop is impressive. You may think me a
bit too "Felix Unger-ish," but a couple of minutes vacuuming every hour or so makes the work
environment more enjoyable, and infinitely more safe.

Standardize
Seiketsu, the fourth step, is to "standardize" the first three components of 5S. A better word
might be to "inculcate," which is to instill an attitude or habit through instruction and
repetition. After your initial "sorting" of items in your shop, and then "setting in order" what is
left, you may find yourself briefly disoriented at times, as in "Now where did I put that half inch
mortise chisel?" Don't worry. Herein lies the true beauty of the 5S system.
If, in the Seiton, or straighten phase, you put that chisel in the right place, you will quickly
adapt to its new location and that location will become second nature. You will find yourself
reaching for and grabbing the chisel without consciously looking. You will enjoy concentrating more
on your work and less on "where is that tool?" And, if you did not put it in the right place, you
will also quickly discover the inconvenience, and you will move it until it is in the right place –
until it just feels "right."
Sustain
As you can no doubt see, 5S is an ongoing process. It can easily become a workshop "way of life."
Once you realize how much more fun your shop time can be, once you recognize that you are spending
more time building and less time looking for tools, jigs, parts, and materials, and once you come to
realize the safety and efficiency benefits of sorting, straightening, and cleaning, you will be
hooked. The beauty is, you will probably be subconsciously hooked. Sorting will become second
nature. Orderliness will become rote. Cleanliness will be a passion (or at least a habit). And
when all of this occurs as a part of your regular routine, you will have standardized the process
(Seiketsu) and in so doing, will have also achieved the fifth "S," Shitsuke, or "sustain."
Implementing 5S principles in your woodworking shop will heighten your enjoyment, extend your
creative time, maximize your space, and enhance your safety. Give it a try!
