Als Ik Kan: As Best I Can#

No matter how long you have been working at the craft, you sometimes flirt with the idea that you can buy your way to better craftsmanship.

I first picked up a crosscut saw at age 8, so I should know better than to fall for this false hope. But occasionally as I page through a catalog or look over someone’s tool collection I think: If I only had that Felder/Lie-Nielsen/Ultimatum thingy. Then it would be easy to be fast/skilled/way sexy to other British brace collectors.

And so now you think I’m going to lecture you on how “it’s not the arrows; it’s the Indian,” or that skill is something independent of our personal pile of brass, rosewood and high-carbon steel.

Actually, I’m not.

I’d like to share with you the tool that has improved my craftsmanship every day I’ve owned it for the last nine years. And I expect it to continue doing this astounding feat for another 30 years.

The tool is a maker’s stamp that my wife purchased for me for my 30th birthday from Mazzaglia Tools in Salem, N.H. It’s a simple piece of steel that’s 3/16” thick, 1-1/4” wide and 2-1/2” long. And cut into reverse on one end is “C. SCHWARZ.”

This is always the last tool to touch my work – if it touches it at all. You see, this stamp is the tool that determines if my work is up to snuff. If I won’t sign the piece with this permanent stamp, then I probably need to throw the project on the burn pile (which I’ve done – right after a satisfying hatchet session). Or perhaps I need to go back and remake some assembly or part of the project, try to bring the finish up to a higher level or find some better hardware.

As an added bonus, the project has to be sturdy enough to receive the beating necessary to leave my name in crisp letters. That beating is necessary because the name stamp has the letters incised in the steel block. As a result, you have to hit the stamp very hard with a hammer into the end grain of your project to make it work.

When done correctly, the letters stand proud of a recessed background that is surrounded by a decorative border. Very nice.

I usually pick someplace inconspicuous to apply the stamp, such as the lower edge of a door stile or the bottom of a leg. Then I place the project on the concrete floor of my shop and pinch the stamp between the thumb and forefinger of my left hand. I rest my hammer head on the end of the stamp (which is now mushroomed over from the beatings from my 16 oz. hammer).

I pause for a few moments to make sure I am ready to bring the hammer down in one fell stroke. You get only one change to do it right. It's just like building a piece of furniture for someone else; there are no do-overs.

I’m just about ready to sign the blanket chest I finished for the next issue of Woodworking Magazine’s summer 2009 issue. But there’s just one little bit of roughness on the chest's lid. Maybe it needs a little wetsanding first.

If you’d like more information about the stamps from Mazzaglia Tools, write for a brochure: 12 Palmer St., Salem, NH 03079. There are several other companies out there that make fancier stamps as well, such as Engraving Arts and Microstamp.

And if you don’t have the coin for a stamp, you can always use a Sharpie marker to do the same job.

Free Construction Drawings for the 2008 Sawbench#

Thanks to expert mousing and clicking of two readers, you can download free construction drawings of the 2008 version of the sawbench featured here last week.

Louis Bois, the draughtsman who prepared the construction drawings for the “Workbenches” book, and woodworker Mike Lingenfelter have both submitted electronic files that will allow you to easily build this sawbench. Plus, Louis’s file also has plans for a mate for the sawbench – I call it “Little Buddy” – that will nest under the “Skipper.”

Louis’s file is a pdf and can be printed out by a wide variety of free programs, most notably Adobe Reader. Mike’s version is a SketchUp drawing that is actually a 3D model, which allows you to take the sawbench apart and see how it goes together. SketchUp is a free program from Google and well worth the download.

Today I put a couple coats of finish on the sawbench while I was finishing a blanket chest for the summer 2008 issue of Woodworking Magazine. When I cannot spray lacquer (I use an HVLP and solvent-based lacquer), I like to finish projects with a custom mix that is difficult to mess up.

I don’t know where I got the recipe for this finish. Several years ago finishing expert Bob Flexner mentioned in one of his columns that he makes his own oil/varnish blends and his own wiping varnishes – instead of paying extra for some finishing company to do it.

I tried this finish years ago and is has yet to let me down. I wouldn’t use this on a piece of furniture that requires a lot of moisture protection (such as a bathroom cabinet), but it’s great for most things.

Here it is: One-third satin varnish (any brand, just don’t use polyurethane varnish), one-third boiled linseed oil and one-third low-odor mineral spirits. Just pour them all into a mason jar and you are ready to go.

I rag it on and then wipe off the excess. Thin coats work best. If I want to make the surface really tactile, I apply it with a 3M gray pad. Either way, it takes only three or four coats to create a nice warm-colored finish that has a nice sheen. The linseed oil helps bring out the figure in the wood. The varnish gives the wood a little protection. And the mineral spirits makes it easy to apply with a rag.

I sand the finish between the second and third coats with lubricated sandpaper or a sanding sponge – something around #300 grit. Sure, it takes longer than lacquer. But in February, it sure is faster than waiting for a warm, sunny day in Northern Kentucky.

Speaking of warm days, next weekend I’ll be at the Lie-Nielsen Toolworks show in Oakland, Calif. If you want to stop by, I’ll be there only on Saturday (my flight leaves Sunday morning). I’ll be selling books and will give a lecture at 2 p.m. Saturday on workbench design.

As a bonus, you can meet my wife, Lucy, who will be helping me at the booth and offering counseling to any members of the “Wives Against Schwarz” who happen to attend the free (repeat free) event.

This Year’s Model: The 2008 Sawbench#

I end up giving away all of the sawbenches I build to woodworkers who give me those wet, doe-eye looks that say, “I don’t think I can build one.” That’s ridiculous, of course, because these things are as easy to make as a box of brownies. But I’m soft, I suppose, like the resulting brownies (always undercooked, natch).

The downside to my sawbench charity is that sometimes I end up without any sawbenches in my shops, which makes me nuttier than squirrel poo. The upside, is that I get to make more sawbenches, and each generation gets a little better.

This weekend I built the sawbench that me and my students will be building during my handsawing classes in 2008. This example can be built from one 2 x 8 x 10’, and it took me about four hours to do – I machined all the stock flat and cut all the joints by hand.

This sawbench is a little different than the others because it’s designed to be a hand-sawing exercise. All the joints are entirely saw-cut. No boring. No mortising. No chopping.

Now if you’ve gotten to this point in the blog entry and are wondering “What in Moxon’s name is a sawbench?” then check out this old entry on my blog at Woodworking Magazine. Sawbenches are magical devices that make full-size handsaws really work (handsaws stink at bench-height, except for overhand ripping). Plus, I assemble carcases on them, use them as stepstools, plane table bases against the sawbench’s bird’s mouth, and eat my lunch while sitting on one.

I don’t have construction drawings drafted for this bench yet, but you don’t really need them. Here are the basics: Make the bench about knee-high. This one is 19-3/4” high. The legs are angled 10° off 90°. The legs are notched at the top at 10° to fit into mating notches in the top. All the stretchers are attached to the legs with half-lap joints. Glue and screws keep everything together.

Here’s my materials list:

1 Top        1-1/4” x 6-3/4” x 32”
4 Legs        1-1/4” x 2-1/2” x 21”
2 Long Stretchers    1-1/4” x 2-1/2” x 26”
2 Short stretchers    1-1/4” x 2-1/2” x 12”


The only slightly tricky thing is cutting the feet so the sawbench sits flat on the floor. This is great fun to do once you know the trick. First put the sawbench on a flat and level surface. Then take small wooden shims and shim under all the feet until the sawbench is level on both its length and width.

Then take a small block of wood and cut an 11° bevel on one edge. Place this on your known flat surface and use the block to mark all around the legs of the sawbench (the beveled end allows you to make the outside angle of the legs).
 
Then clamp the sucker to your bench and saw the feet to your lines. This might seem hard. It’s not.

As always, I plan on keeping this sawbench until I retire. But that’s not likely to happen. Plus, I need to build another version that uses lapped-dovetails for one of the advanced classes I’m teaching in July.

Why I Like My French Bench: Reason Numeral Quatorze#

One of my early workbenches was more than 30" wide. At first, I was thrilled with this width as it allowed me more places to pile junk as I worked on a project.

Then one day I was working on a toy box for a nephew and I wanted to level the finger joints. After fussing and flailing around like a rooster in an empty henhouse I conspired to sleeve the carcase over the end of the bench.

Denied. The bench was too wide. Zut alors!

Lucky for me, however, the bench was a big solid-core door (it had once been the door to our building's cafeteria). So after 10 minutes on the table saw, my benchtop was 24" wide and the carcase fit perfectly over the end.

I like narrow benches for a lot of reasons. I can reach the tools on the wall. They allow me to clamp all around typical carcases right to the benchtop. But I really like a narrow bench when I have to level dovetail joints on a carcase or cabinet.

That is when the Roubo really shines. Today I was leveling some finger joints on a blanket chest and just slapped the thing onto the bench as shown in the above photo and went to work. In the photo I'm knocking down the end grain with a Shinto-rasp (it saves me sharpening time on my block plane when I start with the coarse tool).

Heck, even the 16" overhang on the end of the bench contributes to my bliss. Most carcases are stable with that amount of support, and the legs below the top help brace the work as I flail away on the end grain.

When the carcase is a bit small, like this blanket chest, I have to switch to an outrigger platform (shown below) to work the ends. But I'm still working against the entire benchtop – the top, the right leg and the stretchers. Having them all in the same plane reduces the amount of clamping I have to do to secure my work.

Taming Handplane Tear-out: Two Addendums#

There is something deeply and dangerously engrained in our culture about the expression “going with the grain.”

Not to get philosophical, but I consider that expression to be the embodiment of our civil culture. That is, if we cooperate with the other people around us, then everything will be OK (taxes get paid, kids go to school, wooden boards get smooth). And If you go “against the grain,” then bad things happen (cats and dogs living together, mass hysteria, tear-out).

Here's why this thinking is dangerous: It assumes there are only two ways to accomplish things - either you work with the grain or against it. That's ridiculous.

Some of a handplane's most awesome powers can be unlocked by working across the grain of the board. Working across the grain - what Joesph Moxon calls “traversing” - allows you to easily remove the cup out of a board. Think about that for a second. If you take a cupped cabinet side and plane it “with the grain” all across the board then you will end up with a nicely planed cabinet side that is still cupped.

Working across the grain has another amazing and distinct power: It eliminates tear-out. Working cross-grained means that your cutting edge is not going to lift up the grain, lever it upwards and tear the wood fibers ahead of your cutting edge (that's the long-winded description of how tear-out occurs). Instead, working across the grain simply severs the fibers. They don't get lifted.

Now, the resulting surface isn't ready to finish. It looks wooly and dull. But it isn't torn out. And your board will be flat.

That's an ideal place to be when you are working difficult woods. To understand why, let's look at how I worked the slightly cupped front of a curly maple blanket chest this week. First, let's plane this board “with the grain.”

Working with the grain: First take your jack or fore plane and work the high edges down so the panel is fairly flat. Working with the grain on curly maple will produce some tear-out. Then work the panel with the jointer plane to remove the rough surface left behind by the fore plane. Working with the grain will continue to leave tear-out behind over the entire surface of the board. Then take your smoothing plane and remove the tear-out and tool marks left by the jointer plane. If the tear-out is deep, you will typically need to make 10 to 15 passes over the panel to get most of the tear-out removed. Deep patches will have to be scraped or sanded.

Working across the grain: Flatten the panel with cross-grain strokes of your fore plane. No tear-out will be left behind. Now follow up with cross-grain strokes with your jointer plane. Begin to work diagonally across the grain, but take care not to work at an angle where tear-out appears. Again, done correctly, you will have no tear-out. Then follow up with your smoothing plane and plane “with the grain.” Because there is no tear-out to remove, you only have to remove the hollows and high spots left behind by the jointer plane. With my tools, that typically will be four or five passes over the board.

Working across the grain reduces the amount of work I have to do on a board and it reduces the amount of sharpening I have to do on my smoothing plane. Both are good things.

Now, I would be remiss if I didn't mention the two disadvantages of working across the grain. First, you will splinter the far edge of your board or panel. To remedy this, you can plane a small 45° bevel on the far edge, or leave your board over-wide and rip it to final width after planing. The other disadvantage is that working cross-grain tends to dull your tools faster. But this isn't as big a deal because you are dulling the fore plane and the jointer plane, which don't have to be hair-splitting sharp anyway.
 
In addition to working across the grain, here's the other weapon you should consider: a small high-angled smoothing plane. Tear-out can be localized on a panel. If that occurs, you have several choices: Plane the entire panel some more to remove the tear-out (laborious), scrape or sand the torn-out area (then you'll have to sand the entire panel to make the panel look right), or plane out that small area by working localized.

Short and narrow smoothing planes allow you to sneak into these areas without a lot of extra work. I like to use my little Wayne Anderson high-angle smoothing plane for this job (it's about as big as a block plane). You don't have to invest in a beautiful plane like this one to do the job, however. Any low-angle block plane that has been sharpened with a high angle and a curved cutting edge will work wonders.
