Compass Inlay Shop cut veneer and hot sand are all you need to add a nautical decoration to any project. by Glen D. Huey We all occasionally need a little direction – it’s easy to get off course. As man first began to sail across oceans, maps were drawn to help give direction and guide ships. The “compass rose” came to life, but for most woodworkers, the compass rose is purely decorative. I’ve been aware of it for many years, first seeing the inlay associated with boxes and trunks in areas of New England that have strong nautical ties. But it was a Pennsylvania desk-on-frame – the inlay was centered on the desk’s lid – that prompted me to research the design. The compass rose, on a map, indicates direction, although the points represent winds. The four major winds – today, as it was in the pre-1500s – are North, South, East and West. The first letter of each direction is transcribed just beyond its point. These are the cardinal directions. Around the time of Christopher Columbus, Portuguese mapmakers used a fleur-de-lys to signify the north wind and a cross for the east, which indicated the Holy Land. A set of four half-winds, the ordinal directions, was added along the way. Those points are shorter 360woodworking.com 1 in length on many maps, as they are in my inlay. To provide more precise bearings, 16 more points were added to the design. This is where the term “rose” was introduced because on a map, all 32 points have the appearance of a rose with all its petals intact. A four-point compass is only the major winds – I seldom see this design used on furniture. The inclusion of the four ordinal winds makes the design an eight-point compass, which is the topic of this presentation. All 32 points is technically a compass rose. The North Atlantic Treaty Organization uses a four-point compass for its While you may think that the decline in printmaking and sailing has lessened the notoriety of these symbols, many are still in use today as the symbol of well-known organizations, such as the North Atlantic Treaty Organization (NATO) and the Seattle Mariners major league baseball team. (Would you expect anything different from Mariners?) After you've four-squared your stock – make a fresh cut, use a blade tooth to set the thickness of cut, then mark the edge to help set the stock for a second pass. Shop-cut Veneer For me, working with commercial veneers is a real pain. With veneer thicknesses at 1/64” and shrinking, it’s way too easy to scrape or sand through the veneer as you work. Because of this, I’ve elected to cut my own veneer, especially when the need for small amounts arise. This eight-pointed compass inlay meets that standard. I chose maple for the compass because I have scads of scraps lying about my shop. Due to the overall width of each inlay piece, a scrap of 8/4 material worked out great – each strip was split into 4-1/2"-long pieces, then each piece was cut in half lengthwise to make two pieces for inlay. To slice off my pieces, I ran one edge of the stock over the jointer, then made a rip cut at my table saw to bring the two edges parallel. Using the tooth of the saw blade, I adjusted the fence to provide a near 1/16" offcut, which would be my working stock. Before ripping the first piece from the blank, I used a sharp pencil to mark the board’s edge. After each slice, the blank is moved to the line to reset for another slice. (Some woodworkers clamp a stop in place and bump the blank against the stop with each slice. Using this technique, I find variations in thickness are common due to the unequal amounts of pressure set against the stop.) In all, I needed two strips for the compass inlay, or about a dozen 4-1/2"-long pieces. I’d begin with 24 individual pieces. Yes, there are extras included. It’s rather simple to hit the layout line as you adjust the fence for the second cut. With each pass a usable thickness of veneer is made in the shop. 360woodworking.com 2 Visual Depth I’ve always admired how scorching thin pieces of wood – know as shading – significantly adds to the overall look of inlay. This inlay is no different. Each “petal” is made up of two pieces that have one edge each toasted in hot sand. When the married sections group together with the other seven similarly shaded pieces, the design appears to bend inward or outward, depending on your perspective. What you need to shade your veneer is sand, a vessel to hold and heat the sand and a good heat source. Each of these components influences the operation in some manner. How much, though, I don’t know. stove. (Thank you Rob Millard.) Today, a camp stove is my heat source. A side benefit is that a camp stove elevates the pan and sand off your bench to hold it at a good working position, and the sand heats in no time do to the direct flame of the gas burner. It’s easy to regulate the heat, too. Work Begins in Earnest When the sand is hot, position a piece of veneer so that it’s sticking into the sand while standing on edge. Leave the piece in the sand until the edge begins to shade. Notice I wrote shade, not char. Wood that is charred is like charcoal or ash and that needs to be removed. If your sand is at its full temperature, you can gauge the time that each piece needs to be toasted. If you’re like me, shading is a moving target, because my patience wears thin and I begin the process too quickly. Pieces that are near a 1/16" thick should shade in about 20 - 45 seconds. Again, it depends on the heat and on the thickness of your veneer pieces. Check the veneer often until you get a handle on the time needed to darken the edge. Shade all the pieces, trying to keep the edges lightly colored – I have a tendency to allow my sand How deep in the sand you position your veneer pieces influences the overall shading – some woodworkers feel that finer sands shade in a different way. There are woodworkers who feel that the type and grain of sand can change the shading on the workpiece. If that means traveling to the far reaches of the world to gather sands off foreign beaches, count me in. Somehow, I don’t think that’s the case. In fact, burning is burning in my book. The sand I use is simply play sand purchased from a hardware store. It does the job, so I stick with it. I will take a stand on the vessel needed to heat your sand. While you can get by using almost any pan, a cast iron pan is best. Not because it effects the sand in any way, but for the same reasons seasoned cooks prefer cast iron for frying chicken – it’s an ideal heat conductor, and it heats evenly and holds a consistent temperature. Plus, it’s inexpensive and lasts forever. For years I used a portable electric burner to heat my sand, but that’s before I was turned on to a camp Sand, a good, reliable cast-iron pan and a strong heat source helps transform plain veneer into works of art. 360woodworking.com 3 Stay close as you shade your veneer. It’s easy to overtoast the thin wood pieces. Those pieces (as seen in the right-hand pair) are tossed out. Shop-made veneer can be worked using the same hand tools as regular-thickness lumber. The working methods are similar. With the edges trimmed and straightened, join the two pieces using blue tape – veneer tape is OK too, if you have it available. Too much stretching of the tape as it's applied can cause the pieces to flip up as if it were butterfly wings. A single piece along the length adds support. shading to get too dark, yet usable without a lot of planing. In the photo at top left, it’s rather obvious as to which set of inlay pieces are charred beyond use or not quit shaded enough, and which set is OK. The too-heavily shaded piece would be trashed, the lightly shaded piece is OK to use and the other two pieces are what I look for in shading. After you’ve decided what’s good and what needs to be thrown out, make sure you have enough pieces. Pair the pieces to a pleasing match. If you need to trim the shading or straighten an edge, use a plane with a light stroke. Position the two halves together and check the fit. Matching the edges of inlay is similar to that of gluing boards into panels. When you’ve got a tight fit and the shading is where you want it, tape the two pieces as one. I prefer using blue tape. I don’t see the need to use veneer tape, unless you have it lying about. With blue tape you can stretch it a bit to help drag the two pieces tighter. But if you stretch too much, your inlay pieces begin to spring up like a butterfly. Begin by placing tape across the two inlay pieces – this is where you can pull too tight. Before setting the pair aside, place a section of tape along the length of the inlay. 360woodworking.com 4 A Pattern Helps Because there are a number of these pairs and each needs to be marked and cut to layout lines. I find it best to make a pattern even though there are actually two different designs being used – the shorter design is simply a pair that’s been adjusted. I made my pattern from thin, hard plastic – an old cassette tape box – knowing that it would be used many times. To make the lines easy to mark and cut, I placed a layer of blue tape over an area on my plastic sheet and drew the design. That makes it easy to cut the design using a band saw. It’s also easy to shape the pattern to final size using sanders or files to exactly hit your layout lines. Due to the number of individual pieces needed to make the compass-point inlay, a durable pattern is a smart idea. With your pattern complete and shaped, lay one of your pairs out and transfer the design from your pattern onto the pair. Easy peasy. The trick is to use a sharp pencil or marking knife to trace the pattern. Do one at a time, or do them all. It’s your call. Using a band saw to cut the points is quick, but there's more clean-up involved with the process, so the overal amount of time is longer. If you use your band saw to trim the pieces, plan to use your plane to straighten the cuts and bring the pieces to the exact layout lines. Decisions to Make As I began trimming away the waste to produce my completed compass points, I began at my band saw. This technique works, but it causes a bit more work due to the fact that you need to better trim to the layout lines – unless you’re astute at band saw work. Cleaning up to the lines is easily done because you can treat these pieces as regular boards – a sharp handplane makes quick work of any additional trimming. Plus you need to take a quick look now and again to make sure you’re not moving past the lines. A second method that I used and found to work OK, is a sharp knife. It’s easy to do, but there is a chance that you’ll undercut the pieces leaving a bevel at the edges. You’ll need, of course, a firm If you use a knife to trim the points, the potential of the knife's point to follow the grain and stray from the layout line is strong at times. straightedge against which you run your knife. And it’s a bit of a challenge to hold the straightedge secure without it moving slightly as you cut. Also you need to pay attention to your backer material. A knifepoint tends to follow grain lines if allowed to. 360woodworking.com 5 Far and away, the best technique I used during this process was to clamp a straightedge scrap (plywood in my case) exactly at my line, then use a saw to trim away the waste. This is akin to using a veneer saw, but there’s no need to run out and purchase a new saw if you don’t already own the saw. My Dozuki worked just fine. 21/2" 37/8" 13/8" 19/64" 15/8" I found that using my Dozuki was the best method to trim the points for my compass inlay. The clamped straightedge acts as a guide for the saw. Each method works. Give them all a try, or use the one that you think would be best suited for you given your set of tools and abilities. Trim the waste from each of your pairs. 3" 13/8" 19/64" new lines before working the next pair. Also, make sure you join a shorter point to a longer point then continue that pattern until you’ve made up the entire inlay. Move to the next point and join it to the two just completed. Each step is the same. Before long, you’re fitting the last piece to the puzzle. You should be able to slip the last pair into place and be done, but that’s only if the angles are dead on. My guess is that they won’t be perfect, so you’ll need to trim a bit more of the angle – increase the angle or decrease it, depending on your opening. It’s a “work in small steps” process. Or, if you have plenty of extras, go big or go home. I worked small. What’s In, What’s Out? Before moving forward, select the best eight inlay pairs in your collection. These become the compass points you’ll use in your inlay. Separate the eight pieces into two groups of four. Make this decision based on the amount of shading, how tight the pieces fit together or some other qualifier that stands out in your mind. Place the group of four better pieces (your cardinal points) aside. Take the second best four pieces, which will be your ordinal points, and make the necessary layout changes to the design to bring the lengths down to 3" – in other words, take 7/8" off the long-tail ends of the four without changing the width at the 1-3/8" mark. This requires two additional cuts. Assembly of the points is simple. If you’ve hit the lines of your layout just right, the shorter-length edges align nicely. If you’ve missed the lines some way, don’t despair. Align the two points with the shorter-length edges touching, then mark the shorter of the two edges onto the longer. Trim to the It’s important to alternate the two different lengths of points as you assemble the inlay. With the points trimmed and sized (four long and four short), the inlay begins to take shape. 360woodworking.com 6 Inlay Insertion When you’ve wrapped up the assembly stage, you’re looking at the face of your eight-point compass. Before you can inlay the piece into your project, you need to reverse your tape. After assembling the inlay, you need to flip the design and cover the face with tape. The haphazard tape job on the back is removed. As you install your inlay, you'll want to make sure you orient it in the same direction each time. Mark the top, bottom, left and right points. With the perimeter sketched, carefully incise the lines with your knife. This allows you to easily register your chisels as you trim to the layout lines. Lay the inlay face up on your bench or some other surface – I used my table saw table so it was easy to peel away the tape – then cover the inlay with strips of tape. A sharp utility knife is perfect to slice the tape at the edge of your inlay. After all the points are trimmed, peel the tape from the back face – hint: it’s the side with the tape running in all directions. The work to layout the piece that’s to receive the inlay begins with two lines set at right angles to one another. This is used to position the inlay. (Also, it’s a good idea to label the inlay with directional guidance, such as T for top, B for bottom and so on. This allows you to correctly position the inlay any number of times.) Position the inlay at the layout lines, then stick in a couple of pushpins to hold things secure as you work. (Holes from the push pins show at the end, so exercise restraint. Using a sharp pencil, mark the outside of the inlay onto the work-surface. With the pencil work done, use a straightedge and knife to run over the lines to provide a bite for your chisels. All that’s left is to excavate the waste area. In comes your router. The easiest technique that I’ve found to remove the waste is to use a router with a small bit; I suggest a 1/8" up-cut router bit – you can do this work using a regular router, but a plunge router is better. Set the router’s depth of cut to match the thickness of your inlay. Slowly work around the inlay design wasting away the interior. The small-diameter router bit allows you to easily reach into the point’s tip. Remove the waste working back and forth or up and down inside the design. Work up to the layout lines, but do not hit the lines when routing – it’s not the end of the world, but it’s also not a good thing. The majority of the excavation work to lower the inlay area is quickly accomplished using a router and small-diameter router bit. 360woodworking.com 7 Preparation is key to installing the inlay, especially if you’re using hot hide glue. Have your glue heated and clamps handy. If you watch close, you can see the location of the router bit as it cuts through the stock. Finally, work around the circumference of the inlay using your chisel to deepen the lines, and to remove the remaining waste left at the edge. The chisel edge fits directly into the knifed lines, which act as a guide. Time to get prepared to inlay your piece. Assemble any clamps you’ll need – I used three handscrews – along with a piece of wax paper large enough to completely cover your inlay, a scrap of wood also as large as your inlay and your glue. I’m not big on hide glue, but in this case I’m looking for something to help fill any over-cut lines so hide glue works great. You could easily hammer veneer the inlay in place, but the process I describe can be used with any type of glue. Also, you’ll need to elevate your project so you can get the clamps positioned to get a nice hold, unless you plan to clamps everything tight to your bench top. Spread the glue into the recess, and set the inlay in place. Toss a piece of wax paper over the inlay followed by the board, then add your clamps. Move quickly so you can get everything aligned before the glue begins to set. When your glue is dry, remove the wax paper – it peels away easily. To clean up the inlay, grab a card scraper and have at it. All you should be doing is scraping off the excess glue. If, by chance, your inlay protrudes from the project, it’s OK to bring it down to level – the shading is completely through the Online Feedback: Ask a question or leave your comment about this article on our website. ©2014 4 Square Media LLC. You could hammer veneer the inlay if you're using hot hide glue. If you work with other glues, however, pressing the inlay in place is best. inlay pieces, so while you may remove some of the shading, you’re more apt to lighten it than you are to make it disappear. From this point on, treat your inlay as you would any board in your project. Many eight-point inlays you find use a light and dark wood, but I followed the pattern found on the piece I was copying, but there’s no reason why you shouldn’t let your imagination fly when designing your inlay. Have fun with it, but make sure you stay on course. Wax paper is the key to pressing the inlay into position without any worry of unwanted adhesion problems.
