It’s a responsibility

Wednesday, March 10th, 2010

Make a list of the things that a woodworker needs to do his or her craft.  What would you put on it?

Tools would be up there. A place to work would be nice. A way to support and secure your work wouldn’t be bad.  Maybe a few measuring devices…

Oh, and you need wood. Depending on the size of the project, sometimes, lots of it.

Maybe hard, durable woods like maple or hickory.  Maybe woods that work well for carving like mahogany or basswood.  Sometimes, you need inexpensive stuff that works well, like southern yellow pine or red oak.  Veneers. Plywood.

Even the ubiquitous 2×4 whitewood stud to make push sticks and other shop jigs.

Wood is used in a wide variety of applications.  There’s furniture making and construction for sure, but it’s also used in papermaking, chemical products – even food production.  But, for many years around the world, trees were cut down with little thought to the impact on the existing forests.

In many western European countries, going at stands of trees with the axe was vital. Countries such as England plowed through their native forests harvesting timber for ship building, dwellings, bridges and other structures. It became an implied duty for the wealthy landowner to sow a handful of acorns on his property to help ensure there would be enough native wood to keep the Royal Navy afloat.

Then, the colonization of the Americas happened. Settlers were stunned by the incredible number of trees to be found everywhere on the continents. It’s been said that a squirrel could cross from the Atlantic Ocean to the Mississippi River by hopping from tree branch to tree branch, never having to set foot on the ground. Soon, axes were hard at work, harvesting lumber for domestic – and exported – uses.  Millions of acres were also cleared to make room for the farms to feed the burgeoning population.

Fast forward to the early 20th century.  Many of those lush forests were now nothing but an empty landscape, devoid of anything but the occasional ragged stump left over from the clear cutting operation.

Fortunately before all of the virgin old-growth forests were lost forever, government and industry sought ways to slow or reverse this alarming trend. “Without wood, there’s no woodworking.  Period,” said Eric Poirier of Bell Forest Products. “That’s why it’s extremely important to everyone involved that responsible forestry practices are followed as we keep moving into the 21st Century.”

To that end, responsible lumber merchants are active partners in combating the illegal harvesting of domestic and imported hardwoods. “Wood is one of the most important renewable resources, but only if it’s harvested responsibly.”

How do retailers ensure their supply meets stringent responsible standards? “We only deal with lumber wholesalers and log dealers who actively combat illegal logging.” Eric was very candid about the company’s policies. “We make sure our suppliers have policies in place regarding planned felling, minimum tree diameters and felling rotations to ensure regrowth of the affected area.  When we as retailers – and our customers – demand these practices, the wholesalers and loggers listen.”

How can a woodworker know if their lumber retailer works with responsible loggers?  “Ask lots of questions when you go to your supplier. In today’s world of environmental consciousness, many retailers are touting their practices on their websites or at their stores.  If they don’t – ask.”

One area of specific concern for many woodworkers is the questionable logging practices of developing countries. “Some of the world’s most beautiful wood comes from South America and Africa. Unfortunately, some of those species we love so dearly – ebony and rosewood – were logged extensively and today are very rare.”  To help preserve these important trees, organizations such as the Forest Stewardship Council were created.  This international body’s mission is to slow the overharvesting taking place around the world, with a specific focus on tropical woods.  Founded in 1993, the organization has seen some success in trying to slow the overharvesting.  But, much remains to be done in order to preserve these resources.

After all, it’s not just today’s woodworkers who can be impacted by our actions. “I have two young children.  When they get older – and should they want to woodwork – it’s up to all of us to take our responsibility seriously so they can supply us for generations to come.”

Time to tune

Monday, March 8th, 2010

Music is cool. I keep my iPod strapped to my arm most every day, listening as I go about my business.  If I’m writing at work, it’s classical. On the bike?  Something with a driving tempo to help me keep my pace. And then there is my favorite.. anything with a kickin’ bass groove.

Regardless of the style of music, there’s one thing that all musicians have in common: They know that their instruments are worthless for making music if they are out of tune. Even if you don’t have a musically-trained ear, when a piano hits a note that’s not quite right, you will notice that something’s out of whack.  Same thing with a guitar, a violin – whatever.

That’s why before a performance you can watch band members spending time in a sound check, tuning up their instruments to give the right sound during the show. Pluck the string, tune the string, pluck it again until it’s just right.

Unless you are woodworking in front of a camera or a group of woodworking students, there’s a very good chance that you will be performing for an audience of just yourself. But, the same principles apply.

Tuning your tools is a critical part of the building process. Not only do well-tuned tools perform better – they are also safer to work with. They give superior results for the project you are working so hard to complete.

But, where to begin? For power tools, the best bet is to crack open the owner’s manual or a book or website dealing with your brand of tool. This will give you the know-how on how to tackle this task.

In many cases – especially for your power tools, just getting all of its internal parts clean and free of sawdust is a critical first step.  All of the sensitive gears, tool blade and bit holders and sensitive electric windings perform much better when not jammed up with crud.

Alignment is another critical part of this tuning up process.  Lining your rip saw parallel with the miter slots and blade on your table saw gives superior results and helps to reduce the likelihood you will see a kickback.  Getting those band saw wheels coplanar will increase the life of your band saw blade and how well it tracks. A few moments doing these tasks can save lots of time and trouble later.

And, when it comes to bits and blades, you can’t beat clean and sharp. Get the gunk off your table saw blades and router bits. Plane irons, chisels and hand saws, properly honed to a razor sharp edge, make hand work a breeze.

Does this take time away from woodworking?  You bet. You won’t be able to jump headlong into building.  But, just as with any musician, if you don’t take the time to tune your instruments, your work could very easily hit a sour note.

A Toot for Flutes

Monday, February 15th, 2010

Woodworking projects can be embellished in so many different ways.

Pick out some sweet boards with impressive figure. Mix contrasting wood species. Lay in an awesome piece of veneer. Choose some outstanding hardware. Even a highly-polished finish can make a piece pop.

But, even the most basic woodworking projects made of the most common species of wood can be jazzed up with molded details. You can add a purchased molding to your work, rout a profile on the edge or, if you really want to get fancy, you can do some fluting.

No, I’m not writing about the tall, narrow glass you drink champagne from, nor the side-blown high-pitched instrument frequently used in marching bands and orchestras. Flutes are the shallow grooves that sometimes ornament the faces of columns and flat vertical moldings called pilasters. In stone and woodwork, they are usually in a parallel, evenly-spaced series vertically to a surface.

The flute is actually the groove itself. The area between the flutes is known as the fillet.

The first flutes  ever observed in architecture were carved into stone columns adorning buildings in ancient Greece and served as a visual design element. They can create dramatic shadow lines, and make the vertical elements of a piece seem taller. Surprisingly, Roman columns were typically smooth and polished unlike their Greek predecessors. And, yes, all of those flutes were painstakingly carved into the stone by hand. Hey, neither Rome – nor ancient Greece, it appears – was built in a day.

Today’s woodworker has more than a few options when it comes to adding flutes to pieces. Many lumber yards and hardwood suppliers have a stash of pre-milled fluted material on hand. While this is an easy way to go, it often limits your options. “Many of these pre-milled fluted moldings come in only a few common species, and you are limited on the size, spacing and number of flutes,” said Tim Walter of Eagle America. “You might be stuck with something that looks out of place – either too large, too small, or the wrong grain pattern going the pre-milled route.”

An option that gives the woodworker more flexibility is to mill your own fluted moldings. One way to do this is to set up a router table with a plunge bit (a core box, v-groove, etc) in your router and a router fence. If you route one flute, then flip the board end-for-end, you can route a groove with identical spacing on the opposite side. From there, you can cut the boards to length and apply them to the piece you are building. “That’s one option, but it might look a little choppy,” said Tim. “After all, you are just cutting the flutes at the end. You’ll have to find a way to cap the ends of the molding, and those flutes will end abruptly, leaving an pretty jarring transition.”

A better way to make the fluted profile look neater would be to create stopped flutes. This can be done by lowering a board onto a spinning router bit, running the board the desired length and then pulling the board up from the bit at the end. “That’s one way to do it, but it can be tricky to get all the grooves to start and end the same distance from the end of the board.”

Another, easier way would be to rout the grooves from the top of the board with a plunge router. “This way, you can plunge the bit into the board right on a pencil mark and run them the length of the board. You can get much better results because you can see where you are routing.”

The challenge with this method, however, is keeping the router on track as you make the grooves. On long pieces, a groove that jogs or slants one way or the other will stick out like the proverbial sore thumb. To ensure the router stays on track, many woodworkers turn to a dedicated edge guide. While that prevents movement in one lateral direction, there is the chance that just the briefest loss of concentration can allow the woodworker to pull the edge guide away from the board’s edge. “That’s one way to create custom, hand-crafted firewood in a hurry.”

To prevent this, many woodworkers rely on a jig that clamps the board between two fences, preventing any lateral movement across the face of the board. Tim showed me the jig they sell at Eagle America. It consists of a 3/8” polycarbonate base that mounts to your router’s sub base. The two edge guides are mounted to the main base plate with bolts and knobs that ride in two slots. “You can get infinite adjustments between the two edges that way, and you can rout pieces from 1” wide to 12” wide… more than adequate for the vast majority of woodworking operations.”

The added benefit of the jig lies in the shape of the edge guides. Not only can they be used on straight moldings, they can also be reversed and the smaller edge with ball bearings can be used against the work. This way, woodworkers can rout flutes into a curved or arched piece. “Imagine if you had to trim out the top of a Palladian window. This guide can allow you to make accurate flutes that match the curved profile of the molding. The results can be stunning.”

Eagle America is also throwing in a free round nose bit for woodworkers who order the jig. “We want to make sure that anyone who orders this jig will be ready to go as soon as it arrives at their shop. We don’t want them to have to wait longer to pick up the right bit to make it work.”

While flutes in your moldings won’t guarantee your work will be around 2,000 years from now like the stonework from ancient Greece, they can make your work a real piece of art.

“You are tough to buy for…”

Monday, November 23rd, 2009

My wife and I have a great relationship. We are a good pair of ‘parent partners’ when it comes to raising our boys. We share many of the same tastes in food, friends and keeping our home a pleasant place to live. There are times when we are right on the same wavelength, knowing when – say – it’s time to leave a party because someone thinks it would be cool to start dancing the Macarena.

The one time we seem to disconnect is when we are buying gifts for each other. I remember the time I bought her utility long underwear tops and bottoms – and gave them to her – on Christmas morning – in front of her parents – while we were just still dating.

I am an extreme dufus.

For many years, we would share the same lament whenever Mother’s Day or Father’s Day, our anniversary, the holidays or our birthdays would roll around. What am I going to get for my loving – and ever patient – spouse?

We got to the point where we now write down our gift ideas and slip them to each other. It’s been a good solution, and I’m currently working my way through her’s this holiday season. So far, so good.

But, it’s almost 2010! Pen and paper? So outdated. Besides, aren’t we all going paperless these days?

That’s why many retailers are getting savvy and putting together entire gift sites on their online stores. Every year, merchants are making it easier for those loved ones in your life to pick the right goodies for you.

EAGifts

“The whole reason we started our gift site,” said Tim Walter of Eagle America, “is that we know woodworkers throw themselves into their gift making this time of the year. We just wanted to make sure that you weren’t forgotten about, either.”

As with many other sites, the folks at Eagle America have combed through their entire catalog of offerings to select those handy, just-can’t-do-without items that woodworkers would love to see under the tree. “We put a focus on both essential items as well as some more fun woodworking accessories. After all, fun on Christmas morning shouldn’t just be for the kids, woodworkers deserve some too!”

The gift offerings are also broken into dollar range categories. “We understand that not everyone can afford to spend a lot this holiday season. That’s why we broke the categories down by amount. For instance, if you have kids and they are pooling their allowance to buy you something for the shop, we want to ensure they can find a high-quality tool well within their price range.”

And, for those who may have been extra-nice this year, “There are lots of fun ‘toys’ in there…you know what I mean, power tools! Who wouldn’t want a brand new Fein Multimaster under the tree?”

Of course, you can recommend your loved ones just browse by category, or you could select a few items and put them on your wish list. “Sometimes, you need a particular tool to help you develop your skills. Planting a few suggestions gives the gift-giver some guidance on what you are looking for and helps prevent them from giving you something that you may already have.”

While it may seem like it’s no longer a gift if you plant a few strong hints, remember, you may be helping your spouse, friends or relatives who might be sweating over choosing a gift for you this time of the year. “Besides,” asked Tim, “how many reindeer sweaters does one person REALLY need?”

Be a happy elf…

Monday, November 16th, 2009

This past weekend proved to be one of the most productive I have ever experienced in the shop.  There’s nothing quite like getting holiday gifts built for loved ones.  You know they will appreciate the gesture and proudly exhibit the item you build for years to come.  Yes, as an elf at the North Pole, I was totally stoked!

Send your own ElfYourself eCards

Unfortunately, once word gets around that you are a skilled woodworker… well… the jig is up.  Requests start to come in.  “Oh, you don’t have to buy me anything… something from the shop would be awesome!”

This year, I have now moved up to building ten copies of a project I found in the pages of Wood Magazine.  I can’t show you what they look like all put together, because I don’t want to ruin the surprise for the recipients.

However, I can take you behind the scenes into Santa’s workshop to show you how those elves are busting butt to meet the production deadlines.

Let’s just say that power tools are the workhorses for these projects.  I could easily do the work with hand tools and bang out high quality pieces, but for accuracy, speed and repetition, power’s got it hands down.

OK, some quick math….  since I’m working on a factor of ten, the number of pieces I had to cut includes:

  • 40 uprights
  • 40 rails
  • 40 long rests
  • 20 feet

For joinery for these pieces, I then had to  cut:

  • 80 mortises
  • 80 tenons
  • 80 notches

Needless to say, all of these joinery cuts have to be very precise, since they should all be interchangeable between different assemblies.  I relied heavily on stops, jigs and sleds to get the right set ups for each operation.  Sure, it took some time to get set up to a high degree of accuracy, but once I was there, things sped along.

After about seven hours in the shop over two days this weekend, I managed to have all of the pieces cut to size, all of the joinery cut and the central frames glued up.  From here, there’s more shaping to do on other elements and the final assembly.  Perfecting the sanding will follow, and then the entire project will be capped off by a lovely finish.

I’m hoping that all of the pieces which have to ship to the family will be ready to fly by Thanksgiving week, and then I can get the shop back for a few fun projects that are coming along afterward.

Right now, however, Santa’s little elf has had it…  he’s beat and could use a nap to recover from a long stint in the shop.  Visions of sugar plums – and hitting the shipping deadlines – are dancing in his head for sure.

Holiday Gifts to Bowl them Over

Wednesday, October 28th, 2009

It may be difficult to believe, but the end of October marks the beginning the crazy season.

You know exactly what season I’m talking about. The holiday season is now officially upon us.

You have to buy airline tickets for lots of family visits.  Tense negotiations between husbands and wives begin to decide which family gets each of the holidays. Who is going to cook?  Will you try to do the big Thanksgiving holiday dinner at two separate celebrations?

It’s almost enough to make you wish the holidays would already be over.

Woodworkers often look at this time of the year and get a little shaky as well. After all, now is put up or shut up time when it comes to the craft.  Sure, all year you were bragging about the cool projects you built. Maybe it was that dining room table in April, or that grandfather’s clock you finished in September.  Family members were taking note, and maybe they even suggested that perhaps they would like a little something from your workbench.

When it comes to building gifts for giving during the holidays, I’ve discovered a few immutable truths.  First, I always go small.  Sure, I could build an entertainment center for someone, but come on, there’s no way that would ever ship.  Some of the favorite projects have been keepsake boxes, clocks, desk organizer sets… things you can put into a box and send to those distant relatives. But, after giving them for a few years, well, how many clocks does your dad really need?

The past few years, I’ve also come to believe that the best way to go is to build items that get some frequent use.  Something like a cutting board is always a good choice, because it gets a whole lot of work through the year.

This year, however, Tim Walter of Eagle America brought my attention to a new project that really caught my eye.  They now offer bowl and tray kits that can be easily made using the most versatile tool in your shop, your router!

You know the kind of project I’m talking about… You go to a friend’s house for a get-together, and someone breaks out the potato chips and onion dip.  If your friends aren’t animals, they may offer a classy serving option – something like a tray that is sectioned for the chips and the dip, so they stay in their own cubbies, but they are easily accessible.  Imagine the pride you would feel serving up the chips and salsa to your friends in a wooden chip tray set you built yourself.

The kit comes with the acrylic templates to pattern to cut the sections, and the specialized router bit that removes the wood to form the cubbies leaving a rounded edge flat bottomed section in the tray.  “This is really an insanely simple project that has so much impact,” said Tim of the kit.  “With just a plunge router and some imagination in gluing up the blanks, you can have an impressive tray set to give that will amaze any recipient.  And, since they are so easy to build, you can knock out gifts for both sides of the family without any additional hassle. That makes it twice as easy!”

The basic kit offers the standard wedge-shaped pattern you expect to see on a round chip tray. For the holidays this year, Tim and his busy little elves have come up with a surprise for woodworkers.  “While the basic shape is great, we’ve gone a step beyond and developed some holiday-themed patterns – Christmas trees, snow men and a stocking.  Grab a handful of M&M’s, Hershey’s Kisses, cookies or roasted nuts out of those trays while Gene Autrey croons Frosty the Snowman on the radio, and you will be in the holiday spirit before you can say Jack Frost.”

While the patterns are new for this holiday season, the special bit is usable for every one of the patterns. “As with all of our bits, the Bowl and Tray bit is made of the highest quality materials and ground to a very fine edge.  Once your relatives see the first bowl or tray you make,I guarantee you’ll be very busy building more.” Besides, Tim said, “you never know when we may come out with templates in other holiday shapes… Stay tuned.”

A small, easy to build, easy to ship, ready to use gift that can be brought out at parties any time of the year?  It looks like Tim and the elves at Eagle America have been reading your holiday wish lists.

P.S. For some other easy to build ideas for holiday gifts, Eagle America also offers a few more helpful suggestions…

A Honing Beacon

Monday, October 12th, 2009

My dad was fond of telling me to never discuss politics or religion with others.  I thought this odd advice, but, once I tried it at college, I knew exactly why he told me.  People tend to get very defensive if they feel their beliefs are attacked, and they will push like mad to have you think their way.

I guess my dad could have also added talking to people about their methods of sharpening.  Woodworkers tend to find a way to do something – especially as important as their techniques for putting a keen edge on their chisels and plane irons – and stick with it.

Now, let me make myself clear before I start to ramble on here.  Sharpening is a very broad term when it comes to edged tools.  There are actually two distinct steps in the sharpening process.  The first is grinding.  That involves the rapid removal of material to shape a bevel and remove any damage to a cutting edge.  There are many ways to do this, and you’ll see woodworkers rely on grinding wheels, very coarse abrasives and flat platen grinders to accomplish this task.  While getting the edge ready to be honed is important, it’s not what I am going to cover.

No, I’m talking about the act of honing… progressively removing small amounts of metal in order to achieve a fine cutting edge.  This act is typically performed by hand using careful amounts of pressure with very fine abrasive agents.  Here’s where the interesting discussions get started… and where you will see lots of folks start to take sides.

There are basically five different  kinds of media on which people will hone their edges – oil stones, water stones, sandpaper, diamond stones or ceramic stones.  Each has its boosters and each has its detractors.  Some people will make authoritative claims that one method is far superior over the others – even if they have never used the other methods in question before.  I’ve decided to at least give you a bit of a primer on the different methods and what I hear are the pros and cons of each.

Oil Stones: These stones are typically natural stones quarried from the Earth.  They typically bear the name of the region from which they were harvested – for instance, a hard Arkansas stone is found in a mining area that falls near the Arkansas and Oklahoma border.  There’s not a ‘grit measurement’ given for oil stones – their level of abrasive fineness is inferred from their descriptive name (Hard India, Translucent White Arkansas).  Exceptionally hard, most oil stones do not need to be flattened with another stone for years of use.  They use an oil-based lubricant to make sharpening easier and to clear the swarf – the metal shavings.

The agent that does the cutting for oil stones is novaculite, a silica based impurity that is found in these sedimentary rocks.

  • Pros: The stone stays true longer, giving the best sharpening job.  They have been used for thousands of years with great success.  The oil helps prevent rust on the blades being sharpened.  Lower cost compared to other methods.
  • Cons: The stones can glaze with metal cuttings, making sharpening difficult.  The hard stones sharpen slowly.  Oil makes a mess.

Water Stones: Japanese woodworkers have been using these stones for hundreds of years with great success, and now the stones are now in western shops. Naturally quarried water stones are becoming more rare, so many of today’s are manufactured. The water stones are softer, which means they abrade more quickly, exposing fresh cutting media as the sharpening progresses.  The water creates less of a mess to clean up and leaves no residue.  The stones – especially the manufactured ones – are advertised by their grit size – a 1,000 grit medium stone.  Because they do wear quickly, these stones do need to be flattened, or dressed, frequently to ensure blades and plane irons are sharpened squarely.

  • Pros: Fast cutting.  Only water is used with the stones. Easier to pick up the proper grit size. Most popular sharpening option, meaning more choices for buyers.
  • Cons: Creates a mess.  Water on steel – if not properly tended to – can lead to rust. The stones need extra care to ensure they remain flat. The price can get high for high-quality stones.

Scary Sharp (Sandpaper): At first, you may think this is some kind of joke.  Sandpaper as a medium to sharpen?  You bet… Different grits of sandpaper (400, 600, 800, 1,000) can take an abused edge from butt ugly to razor sharp.  The paper, which does the cutting, is typically adhered to a dead flat substrate, which means you you will always be working on a flat base.  You can use a few squirts of something like WD-40 to help the blade glide over the surface, but it’s totally optional.  Remember, you are sharpening on the sandpaper on top of the hard substrate… so there is the chance that your paper may move during sharpening, dubbing your edges.

  • Pros: Cost – it’s dirt cheap to get stared on. The sandpaper grits can be found at a home center or auto parts store. The paper cuts aggressively, even at higher grits.
  • Cons: Cost – you will be buying packages of sandpaper forever to keep sharpening, and the durability of the sandpaper is limited. You could dub your edges if not careful, meaning that you won’t have sharp edges.

Diamond Stones: Diamonds are a girl’s – and a woodworker’s – best friend. As the hardest substance known to science, industrial grade monocrystalline  (on premium stones) or polycrystalline diamonds (on cheaper stones) can abrade away metal very quickly.  The tiny diamonds are embedded on a flat metal plate with a nickle-based metallic binder, and many have ‘holes’ in the metal plate to allow the swarf a place to go.  Diamond stones are used with a squirt of water to allow for lubrication and swarf removal. These are some of the most expensive stones out there.

  • Pros: Diamond stones cut quickly.  They need no care other than an cleaning and drying after use. They come in a variety of grits to accomplish a number of tasks.  They are the only medium can can be used on carbide.
  • Cons: Price.  Conventional wisdom holds that the swarf generated by sharpening steel on a diamond stone will break the bond with the substrate. Cost.

Ceramic stones: The new kid on the block, ceramic stones are always manufactured.  Basically, a ceramic mixture is carefully mixed with sharp cutting agent embedded within before it is fired.  These stones can be used dry on blades, but they do need to be cleaned with a household abrasive cleaner.  These stones can be quite pricey, but their quality is quite high and they can become lifetime stones for your tools.  They are typically found only in finer grits, so if you do want to work an edge over, it could take some time to remove enough material.

  • Pros: Insanely flat. Can be worked without water or oil. Very hard, durable surface that can’t dish.
  • Cons: Cost.  Can become glazed and needs maintenance to keep cutting medium clear.

What does this mean for the average woodworker?  Well, each of these methods does provide outstanding results and can sharpen just about every tool in the woodworker’s arsenal. If you are using a method that gives you outstanding results, I say stick with it. In fact, if you are using several methods – say a diamond stone for coarser work and an oil stone for finer honing… there’s nothing wrong with that either.

However, I’m sure several readers will weigh in with their preferred method of sharpening. They will tell me that I am way off base and that their method is the only one that works – the others are just trash.

That’s what you get for talking politics, religion or honing!
