My Book on Handplanes

For the last several months, I've been writing and photographing a book on using handplanes in woodworking.  Titled Choosing and Using Handplanes, it describes the various types of handplanes, how to set them up and sharpen them, ways to hold work for planing and planing technique itself.  It also addresses caring for handplanes, buying and restoring old handplanes and how to diagnose and fix various problems encountered in planing.  The book should be completed in November in a paperback edition that will be sold on Amazon.com as well as on my web site and in a Kindle edition to follow soon after that.

A photo of the book's cover is shown here.  If you are new to handplaning, I think you will find this book a helpful resource for getting started.

A Visit to Lie-Nielsen’s Plant


The Lie-Nielsen factory and store in Warren, Maine
My friend Jeff Fleisher and I, along with our wives, had an opportunity to visit the Lie-Nielsen plant last summer. Their shop and factory are located near the Maine seacoast in the little town of Warren. This was a trip we always wanted to make, and it was fascinating to both witness the production of the famous Lie-Nielsen tools and complete line of their tools in the company store.

A box of cap irons, ready for assembly.
There were two attractions—the store and the manufacturing plant. As soon as we got there, we ask for, and got, a brief tour of the plant. As we walked through the facility, workers were busy at such tasks as lapping the soles of planes, operating the CNC machines that make the bodies of the planes and other tools, and inserting plane blades in the large tanks where they are cryogenically treated. We also passed many trays of partly and fully assembled tools of all types, the area where the tools are assembled, and where they are reviewed for quality control and packaged. The plant encompasses several buildings, including a wood shop which we were unable to visit, and employs about 90 staff.

Scraper plane bodies.
We also spent time in the store, where Lie-Nielsen displays their products, plus others' tools, such as Auriou rasps. We took particular delight in examining all the specialty planes, with which we were least familiar. Each of us already has a pretty good selection of standard bench planes, but they too were fascinating, particularly because of their high quality.

Lie-Nielsen saws.
Of course, we couldn't get away without making some purchases. I bought a 1/4 inch mortise chisel and a sock for one of my bench planes and managed not to spend a lot on this trip. Truthfully I already own about all the planes I need, many of them manufactured here in Warren. It was a fun trip and even our wives, who have much less interest in woodworking that we do, enjoyed it.

Learning to Plane - Part VI

There was so much information from this course on hand planing that it's been difficult for me to present it all here in a timely manner.  That's been complicated by the fact that I've been hustling to get my wood processed for the Winchester Chippendale Secretary class I'm taking next week.  That's done now and I have a short time to breathe so I can get back to the subject of hand planing.

Planing Rough Lumber

Continuing the discussion of reading boards and processing raw lumber, Chris Schwarz said that you want a flat benchtop so your boards won't flex downward in the middle while you're planing.  When the heart side of the wood is down toward the bench, plane the bark side by traversing first with a jack plane until the wind is out of the board.  Use a marking gauge to mark the finished thickness around the circumference of the board.  Then use the jointer plane, starting on the diagonal with the mouth of the plane fairly tight.  At first you will get inconsistent shavings because you are getting the tracks from the jack plane.  Eventually, as the boards is flattened, you will get full shavings.  Then you can either plane with the grain or switch to the smoothing plane.  With the jointer plane, start and finish with the strong part of the curved blade off the edge, rather than on the edge, so you don't create a bow.  For interior parts of your piece of furniture, you can often stop after the jointer plane has flattened them; there's no need for the smoothing plane.

Smoothing Plane

Chris smooth planes his furniture after it is glued up when possible.  His advice is to not smooth plane until you have to do so.  As with the other planes, he sets the blade depth by viewing down the sole of the plane and extends the blade until he sees a black line, then adjusts the blade so the curved part is in the center before retracting the blade to the correct depth. 

When planing, he starts partly off the end of the board.  He puts his entire upper body over the plane and uses his legs.  Smoothing plane shavings should be light and fluffy.  It may take several passes to clean up prior marks, though.

Finishing

Aniline dyes don't go well with planed surfaces and will blotch badly.  Pigments lay on top of the surface and work well.  For dyes, briefly rough the surface with 220 grit sandpaper.

Edges

Mark the true face and point to the edge to be trued.  A curved blade lets you cut down the high points.  Use your left hand as a fence.  Drag your fingertips and nails to avoid splinters.

Shooting Board

A shooting board is used to square the ends of boards.  Chris uses a straight edged blade for shooting.  Use a very sharp blade and set it up for a fine cut like a smoothing plane.  He miters the back corner with a chisel to avoid spelching (i.e., blowout).  He draws a line on the end of the board and then shoots until he hits the line, which is behind the miter.

Contest

At this point in the course, having learned about all we could and having set up our planes, we were challenged to square up a poplar board using only our planes.  The prize was a set of books and other items.  I didn't win, but I did learn a lot about using my planes.  I had the books already anyway. 

Scraping

We had time to get in a little extra information and demos on scraping.  We began with sharpening the card scraper.  Chris' method is, he says, the culmination of tests of numerous methods designed for not having much equipment.

You need to flatten both faces and remove the burr that is there.  File the edge at 90 degrees with a file; he mounts the card in the saw kerf in a block of wood.  Only file on the push stroke.  Then he sharpens the edge on stones, holding it at 90 degrees by pressing it against a block of wood.  He starts at 1000 grit, then goes to 4000 and sometimes 8000 grit for edge retention.  He then uses the ruler trick to sharpen the four faces.  Following this, he rubs the edges with a burnisher to push the metal upward and make it easier to turn.  Then he burnishes the end of each edge to turn a hook on each side.  The angle doesn't matter that much.  Use fairly firm downward pressure.  Use as many strokes as you need.  Use a good burnisher.  He does not like the one made by Crown.  The Veritas burnisher works well. 

When using the card scraper, you can either push or pull.  You should get small shavings when you do so, not dust.

Scraper Plane

You use a scraper plane to get a flat surface with any direction of the wood.  Flatten the back of the plane with 1000 grit.  Primary bevel is 45 degrees; secondary bevel is 50 degrees.  A hook on the blade is optional but easy to do.  Use a burnisher at the bevel, then raise it 5 degrees, then do it again.  Put the hook on the back side of the blade.  The Veritas burnisher put a quick hook on the Stanley no. 80 Chris was using for the demonstration.  He used the ruler trick on the back of the blade before putting on the hook.


Wrap Up

And that was the class--two days full of valuable information and hands on practice.  I learned more than I could absorb at the time, which is why I took such detailed notes.  If you get the chance to do this class, take it.  But if you can't get there, then these notes should help you get much of its value.

Happy woodworking!

Learning to Plane - Part V

Chris Schwarz argues that you need a dedicated area for plane sharpening.  After using your planes, dust them off and oil them with either Camilla or Jojoba oil.  The oils won't affect your finish.  In fact, Chris even applies the oil directly to difficult wood or knots to ease planing.  To wax the soles of his planes, Chris uses parafin.  It's essentially mineral spirits.  He waxes after every piece of wood.

Assessing the Wood

Before you plane, look at the end grain.  The bark side of the board is the side where the rings are convex, that is, toward the outside of the tree.  The heart side is where they are concave, or smaller in diameter.  Wood usually cups on the bark side and bows on the heart side.  You tend to get a smooth surface when you plane with the grain.  You can determine that by looking at the edge of the board.  If the grain is rising in one direction, that is the direction you want to plane.  It's like rubbing the fur on the back of a cat; you want to cut with the grain and not against it, which will lead to tearout.  You can also judge from the end grain.  On the heart side of the board, plane from the bottom of the cathedral pattern toward its top.  On the bark side, plane from the point of the cathedral to its bottom.  You would use the same methods to determine the direction for jointing and planing with power tools.  For quartersawn wood, you have to look at the edges; you can't tell from the end grain what direction you should plane.

Assuming the board is cupped, put the bark side down and plane the heart side first.  Once the heart side is flat, flip the board and you can plane without using shims.  When using an end vise, don't put a lot of pressure on the board; the vise can bend it.


Traversing with a Fore Plane

Open the mouth of the plane and use a wide radius (say 8 inches) on the blade.  Plane across the grain.  You can remove lots of wood quickly in this way.  Before traversing (which is what planing across the grain is called), knock off the rear edge of the board, usually with a block plane, to avoid spelching (tearout).

Set the plane on its edge across the board to confirm the existence of a hill.  To remove a hill in the center of the board, plane with the grain to create a slight valley, then traverse the board.  When Chris traverses, he pushes the plane across the board and then pulls it back in a very rapid motion.

Winding Sticks

I took my winding sticks from Philly Planes to the workshop and Chris used those to demonstrate their use.  However, he uses extruded aluminum strips from Home Depot and spray paints one of them black.  Twenty-four to thirty-six inches is a good length.  You can sight at several places on a long board, but you generally don't need to do so.  If you have wind (i.e., the board is twisted), it usually means that two opposite corners are high and you need to plane them.

There's more to tell.  I'll cover it next time.

Learning to Plane - Part IV

Setting Up Planes

There really isn't much setup to do on bevel-up planes, which is one of the reasons they are increasingly popular, especially with beginning woodworkers.  Chris Schwarz didn't have much to offer on setting them up, except to adjust the mouth tightly for difficult woods. 

Bevel-down planes, on the other hand, usually have chipbreakers.  Chris offered that a dished chipbreaker can be honed using a honing guide.  Most people, he said, set the chipbreaker too close to the edge of the blade.  One-sixteenth of an inch is a good distance, except for difficult woods, when it should be set closer, such as one thirty-second of an inch.  Lie-Nielsen makes a standard 45-degree frog but also 50 and 55 degree frogs for difficult woods for all its planes.

Planes are tuned either to remove material, straighten a board or prepare it for finishing.  The jack or fore plane is generally used to remove material.  These are the #5 and #6 planes.  For stock removal, set the plane with a wide open mouth, say 1/16 inch.  Use a curved blade with and 8-10 inch radius.  Back the chipbreaker off; get it behind the curve of the blade.  Use a low blade pitch, say 45 degrees.  For a bevel up plane, set it even lower.

The jointer plane's main job is to straighten a board once excess material has been removed.  Jointer planes are #7 and #8 and run from 18 to 24 inches in length.  You tighten the mouth of a jointer plane; you want to get shavings about .004 or .005 inches thick, so set the mouth at about .003 inches.  Give the jointer plane a strong curve, say .006-.008 inches from the top of the arc to a line drawn between the edges of the blade.  Use an even stronger arc for a bevel-up plane and a 45 to 50 degree pitch.  On a bevel-down plane, the chipbreaker should be backed off to, say, 1/16 inch. 

Smoothing planes should be set with the mouth as tight as possible, .003-.004 inch.  Use a feeler gauge to assess this.  A narrow mouth reduces tearout.  Use a very slight curve to the blade, .002-.003 inches.  Keep the chipbreaker set so it won't clog; 3/32 inch is where Chris starts.  The pitch of the blade can be from 45 to 65 degrees.  The higher the pitch, the less tearing.  Plane softwoods at a lower angle, hardwoods at a higher angle.

Chris argues that it's good practice to use the jack plane and jointer plane as much as possible for smoothing to avoid unnecessary work with the smoother.

Next I'll talk about putting the planes to work on an actual piece of wood.

Learning to Plane - Part III

When Should You Regrind a Bevel?

You only need to regrind after you have honed your secondary bevel, say, six times, if it is taking a long time to get a good polish, the secondary bevel has grown large or if you've hit a nail or dropped the blade and nicked it.  Chris Schwarz grinds on sandpaper, starting with 80 grit and moving to 120 grit.  Grind until the secondary bevel is small, unless it has been damaged.  In the latter case, grind it off entirely.

If you need to regrind on a grinder, grind the point flat, because the point is the most likely place for the blade to burn.  Alternatively, you can quench the blade while grinding.  If you burn a blade blue, hone it and use it anyway.  It will need honing sooner than if it had not been burned, but otherwise it will be OK.

When using a grinder, Chris draws a square line with a magic marker--red shows up best.  Then he grinds the bevel flat using an 80 grit wheel.  He prefers the gray wheels over the white ones because the gray breaks down easier and stays cooler.

How do you tell if your blade is dull?  When you can see a bright line across the end of the blade.  If it's sharp, you can't see the end at all.

Cambering Blades

Some planes will have straight blades.  Others, especially those designed to flatten boards, should have a curve to them.  Jack planes, when set up as fore planes, should have a curve with an eight inch radius.  You would create this camber on the grinder.  Jointer or try planes can be straight or curved.  Chris prefers them curved.  They get a much smaller curve, about .006 inch from the center of the curve to the edge of the blade.  This would work out to a radius of about 37.5 feet.  Bench planes get a smaller curve yet, about .002 or .003 inch.  In case the case of jointer and bench planes, you grind the blade flat, then hone it curved.  The goal is to have enough curve to the blade to avoid tracks and still take a good shaving.

Chris's method is to use a honing guide that allows some rocking motion side to side.  He holds the blade square against the 1000 grit stone, putting heavier pressure on one outside edge, then pulling the blade 10 times.  Then he shifts the heavy pressure to the other side and pulls 10 times.  After that, he moves the pressure to the midpoint between one side and the center and pulls the blade 5 times, repeating that motion on the other side.  Finally, he puts the pressure in the center of the blade and gives it two pulls.  This sequence is then repeated on the 4000 and 8000 grit stones.  There is no need to repeat the ruler trick on the back of the blade.  Stropping is about like using the 8000 grit stone.  Stropping the blade is unnecessary after honing and may even lead to rounding over the bevel.

You also want to trim the corners of the blade.  This only needs to be done the first time you set up the blade and is done by pushing a fine file against the corner of the blade, using a rounding motion.  This helps prevent blade tracks on your work.

Thanks to Jeff Fleisher for these photos.  Next time I'll cover setting up planes.

Learning to Plane - Part I

I've got the planes.  I described these in an earlier posting.  I've read the books.  Especially good are Christopher Schwarz's Essential Handplanes and Thomas Lie-Nielsen's Sharpening.  Now it's time to put what I've been learning into action.

 I started with a wide board of curly red oak that I wanted to use to make some cutting boards.  I set out using my Lie-Nielsen no. 7 1/2 low angle jointer to flatten the board, then my Veritas low angle smoothing plane.  To remove a peak in the center of the board, I first planed a trough in the center with the jointer plane, then planed across the board on a diagonal to remove the high places until the board was level.  Then I used the smoother to produce a surface that barely needed sanding.  The result was good if I do say so myself, considering I started with a tough board to plane. 

I learned a lot from the process.  One lesson was that I need to know more about sharpening.  A second lesson is that I need to know more about setting up my planes for optimal performance.

Fortunately, I'm having a chance to learn how to do both of these things.  As I write this, I am midway through a class on handplanes taught by none other than Thomas Lie-Nielsen and Christopher Schwarz.  The class is being held at the Marc Adams School of Woodworking in Indianapolis.  Already, I've sharpened and set up two of my planes and have taken a perfect thin shaving with my Lie-Nielsen No. 4 smoothing plane.  It was an exciting moment!

I'll have more to say about this class later, along with photos.

Plane Talk

I was once quoted, and not all that long ago either, as saying that I didn't think I'd have much need for planes in my woodshop. I expected to do the vast majority of my work with machines. While my love of machines has not diminished and I intend to use them for productivity, the possibility of enjoying the older methods of woodworking has been growing in me. I'll need to learn the proper use of chisels to hand cut dovetails for the Winchester desk I'll be building. That much I expected. But now I find myself fascinated by handplanes.

I think my burgeoning love affair with planes began when I picked up Chris Schwarz's Handplane Essentials. It's a wonderful collection of essays on various aspects of the choice and use of planes. Since then I've gotten Garrett Hack's older volume The Handplane Book and I'm working my way through it from front to back.

But anticipating work to come, I've also started to collect some planes to use in my shop. The largest of these is the Lie-Nielsen No. 7-1/2 bevel up jointer plane, which I'll first use to flatten a nice wide piece of curly red oak I'm planning to use for a pair of cutting boards. Don't look for this plane on their web site; it isn't listed and may not be offered any longer. Pity, because the bevel up feature will be good for highly figured wood like the curly red oak.

I also have a pair of planes to use for smoothing the surface of the wood--on the cutting boards and later on the drawer fronts of my desk--a No. 4 Lie-Nielsen corrugated sole smoothing plane and a Veritas low-angle bevel up smoothing plane. The latter will be especially good for avoiding tearout in highly figured wood, again like the curly red oak and the curly cherry I'm planning to use for the desk front. The corrugated sole on the former is intended to make it easier to move the plane across the wood.

Other planes I've acquired are the Lie-Nielsen No. 97-1/2 small chisel plane, which I'll use for removing glue from joints and evening the ends of dovetails, the Lie-Nielsen medium shoulder plane for evening up tenon shoulders, the Veritas edge plane and the Lie-Nielsen No. 60-1/2 adjustable mouth low-angle block plane for working the end grain of boards.

Now that I've built up my collection of planes, I feel that I can handle just about any situation required of them.

Now if I only had them fully sharpened and set up for use, I could start on that curly red oak today. Well, perhaps I will!

Preparing to Build the Winchester Chippendale Desk

Recently, I've turned my attention to preparing to build the Valley of Virginia Chippendale desk I wrote about previously. I'm taking the class in June and July from Jeff Headley and Steve Hamilton, who teach at the Woodworking Workshops of the Shenandoah Valley, located in Berryville, not far from me.

The first task was to estimate the lumber I will need to build this desk. I'm going to use cherry for the casework and will probably use curly cherry for the drawer fronts and lid. The drawer sides and bottoms and other interior parts will be poplar. I happened upon a program called CutList Plus, where you enter the dimensions and type of wood for each part. The program then calculates layouts on the boards I'll be using and from that I'm able to estimate the amount of lumber I need to buy.

I hauled in a first load of poplar the other day and have it on the lumber rack and stickered. It should be ready to begin processing in a couple of weeks. Tomorrow I'll call some hardwood suppliers in the region to see if they have curly cherry in stock. My plan is to check it out in the next couple of weeks so it too can be acclimating to my workshop humidity level.

Although the course does not start until June, I'm counting on it taking me weeks to joint, plane and cut to size all the pieces for the desk. This all has to be completed before the class begins. I've put together a schedule that will allow me to do all this without rushing and so far I am on or slightly ahead of schedule. But I'll have to be diligent in order to keep it that way.

In addition to preparing the wood, I'll need to learn some new skills. The case is constructed with hand cut dovetails, so I'll need to learn how to cut these before the class starts. I've never yet cut one. And, some of the pieces of the cherry will need to be hand planed because of their size and in order to avoid tearout. I've purchased a good set of Blue Spruce chisels and several Lie-Nielsen and Veritas planes, so I have the tools in hand. Now I need to learn how to use them well.

I'll be updating my progress as I go along on this ambitious project.
