My Planes are Taking Shape!

On the fourth day of the Scott Meek class on making wooden planes, we shaped the wedges that will hold our blades in place and then began to cut the now rectangular plane bodies to their final shapes.
For my Osage orange smoothing plane, which has a 50 degree bed angle, I decided to create my own body style and so I strayed from the traditional design.

My idea was to incorporate handle-like curves in the toe and rear of the plane to make it more easily fit my hand in use.  So I left the front and rear sections higher so I could shape them to fit my hand.
Some of the shaping is visible on the front of the plane; I did less shaping on the rear
I will probably not make any more changes to this plane, except to polish the rasped areas.  I can do additional changes to fit my hand when I'm back in my own woodshop and after I have spent some time using the plane.

The teak 12 inch jack plane is still being shaped.  I'm following Scott's pattern for this plane, which will have Scott's "wave" pattern on the rear section.  That not only makes it easy to hold and use, but beautiful as well.

I've not yet started on shaping the 22 inch white oak jointer.  That will come tomorrow.

Tomorrow we'll finish shaping the bodies and then work the mouths so the blades protrude just the right amount.

Need I say that I'm having a lot of fun--and learning a lot too!--in this class?  When I update my book on handplanes, Choosing and Using Handplanes, I plan to include a chapter on wooden handplanes, which are quickly becoming favorites in my handplane collection.

Starting to Look Like Planes

In yesterday's class, we made the cross pins, against which the wedges will secure the blade in place, and cut the cheeks off the sides of the plane blocks; until now they had been whole blocks.  Then we cut the center block into two with the correct slopes to bed the plane blade at the desired angle.  My smoother is being crafted from Osage orange, a very hard and beautiful yellow wood.  Domestic varieties are also known as hedge apple and by other names.

I then marked the location for the crosspin, drilled holes through the body to accept it, and glued the cheeks back onto the center blocks.

The clamps came off after a few hours.  I centered the crosspin between the checks, trimmed off the crosspins where they stood proud, and laid out the profile for the plane on one side.  Then it was off to the bandsaw to create the rough outline shown below.

After the clamps came off, the boxy plane body was sawn to rough shape
Next steps are to refine the body shape, hone the blade and fit the blade and the wedge to the plane body.

Day 2--Scott Meek Plane Class

We made great progress in constructing our planes today. Those blanks, like the Osage orange shown, that were glued with epoxy, came out of the clamps this morning.  We jointed the bottom and one reference edge, then planed the blanks to rough width.

The Osage orange blank viewed from the end on; doesn't look like much does it?
 Then we cut the cheeks from the edges, leaving behind a center block to be further cut to accommodate a blade. 
The center sections of two planes marked and partially bandsawn, awaiting further work
We marked up the center blocks for a plane blade bed angle of 45 degrees, except for my Osage orange smoother, which will have a 50 degree bed angle.  We also marked the reverse slope, the shape of which is less critical, needing mainly enough room to get the fingers into the opening to remove stubborn shavings.  These cuts were made freehand (following a line) on the bandsaw.  The bedding angle cut was made on the table saw.

The forward slope was sanded on a belt sander, the bedding slope on a strip of sandpaper attached to a slab of marble.  We filed slight 90 degree bevels on the bottom of the bedding slope.

We measured and made crosspins (not shown) and rounded their tops.

Tomorrow we will drill the locations for the crosspins, install dowels in the front and back corners and glue the cheeks back onto the center blocks.  After allowing time for the glue to set up, we will begin the process of shaping the blanks into something more closely resembling the planes we will take home with us.

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 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.
