Here is some help with pencil lines on dark wood. Though knife lines can be modified to produce the advantage of a physical feel for the correct location of a tool such as a chisel, most layout in woodworking is done with pencil lines. Marking out the tails for tails-first dovetailing and curved layout lines for bandsawing are examples.

Graphite pencil lines have a bit of sheen which helps their visibility but I still find them difficult to see, particularly if the line is along the grain on a wood like Claro walnut, which is dark and has color variations. So, motivated particularly by my love of Claro, I have experimented with various white or light-colored pencil and ink lines.

I tried Japanese ink “brushes” and very fine point drafting pens. I do not like marking out in ink because I do make mistakes and have no immediate plans to cease, so no ink for me.

I have scoured art supply stores and experimented over the years with various white pencils, occasionally trying bright yellows and other colors. Most are too soft to retain a sharp point for a practical amount of work.

The best pencil I have found is the Sanford/Prismacolor Verithin White #734. It can be sharpened to a point that is nearly as sharp as a #2/HB graphite pencil. It wears faster than a #2 but the point holds up well enough, especially if used with a light touch. It makes a nicely visible line on walnut. It is not as easily erasable as graphite, but decently enough using a white “plastic” eraser. They cost from 39 cents to a dollar apiece, depending on the quantity and the store.

The top photo shows sets of three lines of #2/HB graphite and #734 White going across and along the grain, made from a single sharpening of each pencil. The graphite lines along the grain are barely visible just above the white lines. The photos below show the same lines photographed from different angles.

An alternative is a white 0.5 mm mechanical pencil refill stick made by Pergamano and available from McAllister’s. I have not tried these because they cost $10 for 10 sticks and I would be concerned that they would break easily. Also, the point of the Prismacolor pencil can be easily altered using sandpaper. This is a more fussy job with a less durable result using 0.5mm lead.

No matter what instrument is used for layout, visibility and accuracy are greatly enhanced by using proper lighting. The two simple rules are strong and adjustable. Strong mostly means close, and the light source must be moveable to avoid glare and to cast shadows only in favorable locations. Every effort should be made to set up good lighting.

White #734 sharpened, I’m ready to indulge in Claro.

I usually approach the completion of a project with hesitancy because I know that, for better or for worse, this is as good as the thing is going to be. I no longer can do anything to improve it, except for marketing, and must accept it. Competing with this is the sense of wanting to get the damn thing out of the shop because I’ve already put enough sweat into it.

Another, more important, very distinct, feeling comes over me. Readers, maybe you can relate. I have a sense of separation from the piece. It is now out of my hands and has a life of its own without any further influence from me. It feels almost as if someone else might have made it.

Well, isn’t that the point of creativity, to make something that stands on its own and is appreciated for what it is apart from its maker? Yes, attention is rightfully now on the object, not its maker. People will, to varying degrees, like or dislike the object. The object is not you, so don’t take the praises or winces too personally. Even though you made it, in this sense it’s not yours anymore and doesn’t need you. Hopefully, it will even outlive you.

This view is in contrast to that of the painted, pierced chic “arteests” of today who seem to prefer that everyone dwell on them more than on what they have made. I believe that we as artists (artisans, craftsmen, woodworkers, whatever you prefer) should be humbled by the degree of mystery that lies in making things.

Yes, this work is personal, but consider the words of James Krenov, “. . . the worth of such things is their whole content . . . [to be] seen – and lived with, in a coming together of sense and observation that will bring quiet joy long after the maker is forgotten.”

It is good to build good things.

These thoughts started to gel as I was browsing a craft exhibit of many wonderful pieces. There were also a few that didn’t quite measure up, at least in one man’s opinion. I wondered what, apart from preferences in style, had formed my view of an object as a creative success or as falling short.

Further, I supposed these considerations could help me with my work. “I work wood, therefore I am??”

At the core of creativity is the development of a powerful, compelling, rich idea. By “idea,” I mean more than a whim or an attractive notion. I mean a driving, guiding force with enough energy to result in a creation. I like the word “concept” for this. Without it, a creative effort really doesn’t stand a chance.

When designing a new piece, I wonder why would anyone, including me or a client, really care about this. One way out is to make ostentatious nonsense or to be different for its own sake. No, I want to make refined work that elicits the “quiet joy” of which Krenov wrote.

Moving ahead, a clear concept produces economy of intent and execution. The artist/craftsman grasps the essence of what he desires to create, and thus driven, marshals the skills and focus to make it be. To get the job done, the intent must coordinate with workmanship and this must be conscientiously sustained throughout the construction process. In other words, consistency of intent should engender consistency in workmanship so that one reflects the other.

OK, nice lines on paper that I’ve got here but I better be able to pull this off. I must have the skill and mental focus to carry this through because no one puts up scale drawings in the living room.

The result of all of this, we hope, is harmony of all the aspects of the piece – form, wood, color, details, and so forth. This is pleasingly evident when viewing the piece. It is so readily evident that it will likely make the viewer blissfully unaware of the sweat it took to get to the final product.

By contrast, inconsistency and disharmony are readily evident. Think brown shoes with a tuxedo (inconsistent intent) or a suit that would look great except for an awkward fit that can’t be ignored (inconsistent workmanship).

I better be clear about where I’m going with this because I’m going to invest a lot of work in it. More than hope that it will “come out good,” I’ve got to think and believe that it will.

More than merely theoretical meanderings, this is the stuff that makes a piece produce that good “Ahhh” feeling. It is a formidable job to have a good idea, recognize and develop it, then sustain it as you execute it with consistent workmanship. I am grateful to be able to make things in wood, it is fun, and at times exhilarating, but I do think it is truly difficult to do well.

Stay with it, you can do it. “Unity and variety,” as Maestro Heath used to say.

As discussed in the previous post, one of the keys to successful work with the jack plane is the use of a vigorous diagonal stroke. To stabilize the board from the pressure in multiple directions, I like to use Veritas Bench Pups, Bench Anchors, and Wonder Pups in various configurations, usually along with regular bench dogs, as shown in the photo above. Other options for use of these handy devices and shop-made stops at the right and left sides of the workbench are discussed in these two earlier posts.

Beware when planing thin boards, say under ½”, which can flex. It may be necessary, for example, to place shims, such as blue tape or veneer, under a convex surface facing the bench for a similar reason that you would not place a non-flat surface on a thickness planer machine bed. Likewise, it is often necessary to place shims under the high corners of a twisted board.

To set the blade projection, I use these steps: I sight from the front of the sole, with light adjusted to reflect off the thin flat at the rear of the mouth (I file that flat when I set up a new plane). I advance the blade enough to see it to correct the lateral adjustment, then back off the projection to a minimal amount. I start stroking the plane on the wood, back and forth, gradually advancing the blade, often using my left hand on the feed screw and my right on the tote. I’ve found this method gives better results than using sight alone, or running a narrow scrap against the blade.

The long infeed length of the Veritas BU jack makes it feel almost like a jointer. It’s easy and natural to move the plane back and forth rapidly without lifting it, like scrubbing the wood. This gives excellent tactile feedback to be able to sense when the surface is approaching flatness.

The Veritas BU jack has some other nice features. The lack of a cap iron (“chipbreaker”) makes swapping blades very easy. I find the little set screws on each side of the plane near the mouth help to quickly position the new blade. The mouth opening can be adjusted in seconds to accommodate different shaving thicknesses. This is far easier than adjusting the frog on a bevel-down plane. I also like the Norris-type combined feed and lateral adjustment mechanism, though some woodworkers do not.

I strongly suggest getting rid of the awful handles that Veritas puts on their planes and get a set from Bill Rittner – I think you will find that they dramatically improve the feel of the plane.

These features make the Veritas BU a good choice for your workhorse jack plane. That said, I also have a 30-year-old Record #5. They each have their advantages, I use both of them regularly, and will not be parting with either. If you want me to declare a winner, I can only say that there’s more than one good way to do most everything in woodworking. I hope these posts will help you find your way.

A jack plane, including this one, is mostly used to true the surfaces of a board and dimension it. It follows coarser tools – the mill saw or, if substantial thickness must be removed, the scrub plane. It is followed by the jointer plane, if needed, and then the smoothing plane or other methods, such as scraping and sanding, to create a finished surface on the wood. Thus, the jack is a fairly rough tool. Yet it is expected to leave a surface without major defects to avoid having to remove too much wood with subsequent tools.

The role of the jack plane dictates its setup. The blade should be sharpened with a moderate camber – a balance between the need to remove wood quickly and leave a decent surface. Judging the proper amount of camber comes with experience, may vary from job to job, and is most easily determined by eye, but it is important to note that a blade that is bedded at a low angle with the bevel up requires more camber, as judged from a 90̊ view, than a blade which is bedded at a higher angle with the bevel-down. Please refer to an earlier post for a full explanation of this.

I prepare the blade with a primary bevel of about 30̊ and a secondary bevel of about 38̊ which, with the Veritas’ 12̊ bed, yields an attack angle of about 50̊. Going significantly higher than this makes the plane simply too hard to push through the wood for this type of work. A smoothing plane is a different matter in this regard. There, fewer and finer shavings are taken, so higher attack angles are practical and may be necessary to avoid tearout.

But wait, isn’t the main point of a BU jack to use high attack angles and prevent tearout on difficult woods? No, not in my opinion. A jack plane does most of its job best when used diagonally across the grain. This makes it easier to accurately remove surface distortions and avoid tearout, obviating high attack angles. I regularly jack plane curly woods diagonally or even nearly perpendicular to the grain.

For the few occasions when a 50̊ attack angle creates significant tearout even with a diagonal stroke, such as with very swirly grain, it is time to employ one of the wonderfully handy advantages of a BU plane. The regular blade can be easily swapped for a toothed blade (sharpened at 40°). This magical blade can manage the most cantankerous of woods.

A further negative consequence of using a blade sharpened with too large an angle (such as 48̊ to produce a 60̊ attack angle) in the BU jack is that it becomes difficult to set the projection of the blade. It is frustratingly difficult to find the middle ground between a shaving that is too light for jack planing and an impractically deep projection, especially if the blade is starting to dull. Imagine trying to pare with a dull chisel sharpened with a 48̊ bevel – you’ll either scrape the wood or dive into it, with little control.

As you near the end of the job with the jack, back off the blade projection to increase accuracy and improve surface quality, thus getting the wood ready for the next stage of preparation.

The next post will discuss securing the board to the bench for jack planing, steps in setting the blade projection, and some particular features of the Veritas BU jack.

I had no specific purpose for this square, but because it looked like it might be a player, I added it to a larger order from Lee Valley Tools. After unpacking the shipment, I nonchalantly placed it aside into the tool well of my workbench.

Over the next few weeks, I found myself picking it up over and over for all sorts of measuring and squaring tasks. This may be the best way to assess the usefulness of a new tool: leave it on the “bench”, like an extra player, casually go to it now and then, and as you become increasingly impressed with its performance, promote it to the starting line up.

Here’s how this tool earned its role as a starter for me. First, it is very handy – small and light. The clean graduations with a sensible height organization and the satin finish make it easy on the eyes. The scales on both legs start at the inner and outer corners and are the same on both faces so I don’t get confused or make errors. I generally prefer to visually split 1/16ths rather than use 1/32-inch gradations but it is helpful to have the 1/32nds on the small legs for fine work.

It works beautifully as a short hook rule, such as to check stock thickness. Also, either leg butts securely against a surface for accurate inside or height measurements. Overall, I like handling the “L” shape more than using a 6-inch rule.

When I evaluated it using a Starrett combination square as the standard, I found it far exceeded Lee Valley’s statement of accuracy. It was straight and square within 0.001″ over its full length.

And, it’s got a 38″ vertical leap and clocks 4.4 in the 40. Just kidding.

As for dislikes, I find the large relief on the inside corner to be unnecessary, and it prevents penciling a line all the way to that corner. (Veritas seems to like this inside corner design. I find it very annoying on their otherwise excellent saddle square.) Also, a flat square like this will be inaccurate if it is held so as to occupy more than one plane when checking a corner. This is not a criticism of this tool but just a reminder of the nature of a flat square and that it does not replace a regular square.

In summary, this little guy is a gamer, a go-to tool in the shop.

From among my habits of work at the bandsaw, here are some that you may find handy.

1- The yellow velcro band placed around the blade is a reminder to tension the blade before work. Starting up the saw with a loose blade is not a happy moment (yes, of course, I’ve made that mistake) but it could be particularly damaging to a carbide-tipped blade. The velcro is placed aside during work so replacing it when the work is done is a reminder to release the blade tension.

2- Much has been written about proper blade tension, but like all tool adjustments, the goal is good performance. The same blade used to saw 8/4 stock will very likely need more tension when it is used for a 10″ resaw. Whether cambering a plane iron, choosing a bevel angle for a chisel, or tensioning a bandsaw blade, it always pays to “close the loop” by using feedback from the tool’s performance to confirm or modify the adjustments. Wood density, blade cleanliness, and heat build-up are just a few of the variables that make it unwise to tension the blade without thought. 

3- After installing and tracking a blade and before going to work with it, it’s a good idea to close the doors on the saw, run it for just a few seconds, wait until it stops completely, and then open the doors to check the position of the blade on the wheels and make sure all is OK.

4- It is easier to follow a layout line when it is viewed with both eyes (binocularly). Sometimes the blade guard or the guide bearing assembly will block one eye’s view of the line, depending on where you position your head.

5- When bandsawing freehand, I always think, “Feed the line to the blade teeth.” This is just the opposite of handsawing and I often have to remind myself to maintain the correct mentality at the bandsaw after I’ve been sawing by hand.

6- The push stick (below) has a rare-earth magnet which allows it to be stored within easy reach on the saw’s frame. The hole is a reminder of which end has the magnet. The short saw kerfs at the front end of the stick, which accumulate as it is used, can grip the corner of the wood as the cut nears completion. The stick has a limited life, of course, so the magnet is in a removable cup.

7- Large sawdust particles inevitably accumulate on the lower tire despite the actions of the wheel brush and the wood plate below the lower bearing assembly. A paint scraper held lightly against the tire as the wheel is spun by hand quickly removes the debris. A “synthetic steel wool” pad such as Scotch-Brite can also be used.

8- The variable-pitch, carbide-tip blade from Suffolk Machinery is a big help in resawing. It also is great for preparing leg stock and any other straight sawing of thick stock. Below is a 10 1/2″ wide Claro walnut board from Northwest Timber which I resawed with this blade. One of the many reasons why the bandsaw is so endearing.

I hope some of these tips prove useful in your shop.

Yes, humble poplar. OK, this is not a species that is likely to evoke lust, but it is a good wood to love. It should not be overlooked for a supporting or occasionally major role in high-end work, as well as duty in utilitarian work.

To be clear, the species under discussion is Liriodendron tulipifera,whose common names include yellow poplar, and, with a bit more cachet, tulipwood and tulip poplar. This is distinct from similar woods: aspen and cottonwood (Populus spp.), willow (Salix spp.), and basswood/lime (Tilia spp.).

Friendly, inexpensive poplar is readily available. My local orange-themed home center carries plenty of dry, dressed 3/4″ thick boards, as wide as the 1 x 12’s pictured below, and sometimes thicker stock. At my local hardwood dealer, sound stock up to 16/4 is available because poplar dries easily and with minimal degradation.

Poplar heartwood is usually pale yellowish green after milling but eventually changes to light brown after exposure. Some boards have deep purplish, green, or other color mineral stain streaks in the heartwood. The sapwood is creamy whitish which tends to develop a tinge of tan. I’ve never seen figured poplar but maybe it’s out there somewhere. It is a modest wood that, in my opinion, is best appreciated for what it is. Attempts to stain it to imitate another wood, such as cherry, end up looking lame to my eye. An exception may be when it is dyed black (ebonized) for use as an accent wood.

Below, left to right: aged poplar, fresher heartwood and sapwood.

Poplar, oh, yea, I mean tulipwood, makes a great secondary wood in fine work. It is hard to find quartersawn, but rift grain for drawer parts and panels can be salvaged from wide flatsawn boards, as seen in the photos below. For novice woodworkers – and we’re all beginners to the extent that we explore and learn new skills – poplar is an easygoing wood that can still yield very nice results. It saws, planes, and glues easily. Its fine texture takes paint well.

 

For utility work, such as storage units, and for many shop fixtures and jigs, poplar is usually my first choice. I also use it very often for mock-ups.

Poplar is a fairly stable wood with tangential and radial shrinkage values of 8.2% and 4.6%, respectively, T/R is 1.8, and volumetric shrinkage is 12.7%, making it certainly more stable than sugar maple and the oaks. It is a light wood, having an average density of 0.42, and surface hardness less than walnut and cherry but greater than white pine. It would suffer as a heavy-use table top.

Surprisingly, though, its stiffness (modulus of elasticity) exceeds that of cherry and big-leaf maple, though it is no match for sugar maple or the oaks. In this respect, it is a better choice for bookshelves than pine, which is considerably less stiff. For its density, poplar has good strength in tension perpendicular to the grain, which produces resistance to splitting, about the same as cherry and big-leaf maple, and much better than pine.

For lots of woodworking jobs, poplar deserves consideration. And some love.
