E Whatever that surface is going to be — the top of a table or desk or jewelry box — it will also be a hallmark of the ultimate piece, and of your woodworking. You probably chose this piece of wood because of its figure, and now it’s your job to flatten it, and to make it smooth and touch-worthy. Sanding would be easy. But, if you sand that lovely, figured slice of tab- letop, either by hand or with a sand- er, you may create an unappealing muddiness. Sanding grinds wood in- to dust, and mashes that dust into, or between, any open fiber or fila- ment left standing upright. Yes, it is true that a heavy film finish hides all sorts of surface textures, and is a good glossy remedy to the effects of Above: a Stanley Cabinet Scraper #80. sanding. Even though sanding, and The #80 gives you more control than even then applying a glossy finish, may a card scraper.

Pat- table or desktop. rick’s Blood & Gore at Supertool gives an excellent description of the Stanley #80. A scraper plane, on the other hand, creates a much more enticing surface because instead of grinding them, it neatly shears the wood fibers. Furthermore, depending on how you sharpen your scraper plane blade, you can get either a matte surface or a surface similar to the satiny one left behind by hand planing. Regular hand planing produces the most sumptuous surface. In general, highly figured woods tend toward the ever dreaded tear-out when being planed, making it even more difficult to obtain a flat and smooth surface. But, using a scraper plane mini- mizes tear out because these planes offer a radical geometrical attack to wood fibers. The plane holds the blade — that’s what the plane is all about, after all — but, unlike other planes, the scraper blade is secured almost Above: a Stanley #12. Note that the blade is perpendicular to the surface of the set at close to a 95° angle, typical of scraper plane blades. Patrick’s Blood & Gore at Su- wood. pertool gives an excellent description of the Stanley #12. Also, a tip: what’s important about a scraper plane blade is how sharp it is. Unlike sharpening to ex- cess — sharpening with a bit of wood- working on the side — in the case of scrapers, sharp is as sharp does. So, the question remains, do you real- ly want to take a belt-sander and grind that surface into dust? Much of the beauty of this piece of woodwork with the beautifully figured wood has come from your relationship with it, your decisions, the wood’s ob- Above: a Stanley #112, which is basical- stinance, your coaxing, the wood’s ly the progeny of a Stanley #12 and #4. compliance, the dance you and that And what a perfect mating!

And, you know that no belt-sander in the world will keep this piece in your arms. The moment you put on those ear phones, you know the embrace is over. Scraper planes and blades carry the feel of the wood to your hands, allow- ing you and your choice of wood to continue as partners. It’s a scraper, not a sander, that will keep you on the dance floor, where smooth is every- thing. And, wouldn’t you know Hock Tools sells scraper plane blades! We also sell a high quality burnisher to form your burr, and otherwise keep your scraper blades in fine, sharp shape. Left: Made for the Stanley #12, 12½ and 112 Scraper Planes, these blades are 3/32" thick (less flexible, most popular) or 1/16" thick (more flexible) by 2-7/8" wide and 5" long with a 45° bevel on the cutting edge. Hardened for a balance of long edge life and burr "rollability" (you do have one of our burnishers, don't you?) you finally have a source of blades for these classic planes. And for the #80 (1/16" X 2-3/4" X 3" long) and the #81 (1/16" X 2-1/2" x 3- 7/8" long) Scraper Planes, too! High Burnishers are essential to scraper carbon steel. blades. You prepare the blade by honing the 45° bevel just as you would a bench plane blade. Flatten and polish the back, hone the bevel sharp. Then, with the blade in a vise, burnish the edge at 15° to produce the necessary hook, or burr. While most others are not hard enough for this demanding application, Hock Tools burnishers are high carbon steel hardened (Rc64) and polished tool- steel rods that stand up well to constant use on scraper edges.

  • Woodworking Glossary, a Comprehensive List of Woodworking Terms and Their Definitions That Will Help You Understand More About Woodworking
    Welcome to the Woodworking Glossary, a comprehensive list of woodworking terms and their definitions that will help you understand more about woodworking. Each word has a complete definition, and several have links to other pages that further explain the term. Enjoy. Woodworking Glossary A | B | C | D | E | F | G | H | I | J | K | L | M | N | O | P | Q | R | S | T | U | V | W | X | Y | Z | #'s | A | A-Frame This is a common and strong building and construction shape where you place two side pieces in the orientation of the legs of a letter "A" shape, and then cross brace the middle. This is useful on project ends, and bases where strength is needed. Abrasive Abrasive is a term use to describe sandpaper typically. This is a material that grinds or abrades material, most commonly wood, to change the surface texture. Using Abrasive papers means using sandpaper in most cases, and you can use it on wood, or on a finish in between coats or for leveling. Absolute Humidity The absolute humidity of the air is a measurement of the amount of water that is in the air. This is without regard to the temperature, and is a measure of how much water vapor is being held in the surrounding air. Acetone Acetone is a solvent that you can use to clean parts, or remove grease. Acetone is useful for removing and cutting grease on a wooden bench top that has become contaminated with oil.

  • PLYWOOD MALLET.Pdf
    PLYWOOD MALLET Slick method of making a mallet - never need to worry about the handle loosening. See my earlier post re ergonomic parameters, apparently you should determine the bevel angle on the striking face based on mallet handle length and the length of your arm from elbow to wrist. Who knew. With three layers of 3/4" plywood, it's 2-1/4" wide, maybe just add a 1/2" layer on each side if you need something a little beefier - or maybe build in a cavity and fill it with lead shot?. The handle winds up only 3/4" thick, thinking that maybe an additional 1/4" layer on either side would let you get a little more rounded profile to the grip area - easy enough to do though (maybe make patterns to use on the router table) and Baltic Birch plywood would be the way to go. Mallet Head Angle By swirt on March 30, 2011 at 6:30 am in techniques, tools I’ve seen this issue come up and get discussed on several forums. A joiners mallet is pretty simple to make, so it is a quick and satisfying shop project to get one constructed, but then the question arises, “what angle should be put on the head?” This is an important question with advice ranging from “we don’t need no stinking angle” to use the angle that allows it to sit flat on a bench. I discovered the answer to this question in a few old Timber Framing books. It makes sense that a Timber Framer would have the answer, as they do more chiseling than most woodworkers, and certainly heavier chiseling than all.

    est. 1978 Sharpening #80 Cabinet Scrapers #80 scrapers are wonderfully useful for smoothing large surfaces and doing vigorous work. Their side handles are easier on your fingers than plain card scrapers, both ergonomically Tools for Woodworking and thermally. Though it's not exactly the same as sharpening a hand scraper, preparing a #80 for use is quite straightforward. You'll start with a different blade shape, sharpen it differently & use the burnisher differently—but all that aside, the process will look very familiar. You're going to sharpen the blade, then use a burnisher to shape the edge into a tiny, high-angle cutting tool. The most visible difference between a card scraper and the blade in your #80 is that while card scrapers' edges are square, the handled scraper's working edge is beveled like a chisel or plane iron. Every- thing in print says the bevel angle should be 45°, but Tage Frid taught that a standard chisel 1. Sharpen @ 30° - 45° angle (around 30°) works just fine—and as usual, he was right. It does work, and if you've already trained yourself to sharpen at 25° or 30°, you won't have to learn to do it at an unfamiliar angle. On a well-used blade, start by filing away the remains of the old worn-out burr. (Scraper blades are tempered softer than plane irons, and can be cut readily with a file.) Next, sharpen the scraper exactly as you would a chisel, right up to your finest stone. You want the edge to be razor sharp to get the most out your scraper.
