Articles, Lessons, and How-to Guides on Lewis-Riggs Guitars GUITAR SHOP 101 c2006 Barry Lewis FRET LEVELING HOW-TO A common request of a repair person is a setup with "low action, no buzz". However, as the action goes lower on any guitar, the buzz increases, so the standard reply could be "which do you want more?". There is a tradeoff for low action, and it is increased buzz. The action goes lower, the buzz increases, and at some point, you cross a line where the buzz becomes problematic, and this line varies from player to player. The ultimate determiner of how low the action can get before buzz becomes a problem is the degree to which the frets are level. By this we mean level relative to each other, so if you put a straightedge on the neck (positioning it so that it in the "lie" of one of the strings), it would make contact with the top of every fret. (Don't be confused with the issue of forward bow, or relief, here. When leveling, we want no relief, we want level. Relief comes into play subsequently, during setup.) When the frets are perfectly level, as a string is fretted, it barely clears the adjacent fret. When the frets are not level, as a string is fretted against a fret that is lower than its neighbor, the string no longer clears the neighboring fret, and so it buzzes against it. The buzz may be fairly minimal, so that you can still clearly hear the note, or it may be so severe that the note is completely choked, or it could be anywhere in between. These are often referred to as dead spots. So it becomes clear that a guitar that has uneven frets will buzz more in some areas of the fretboard than others. On the other hand, on a guitar with level frets, if you lower the action enough so that the guitar becomes buzzy, the buzz will be pretty consistent across all the frets. If your guitar has dead spots, or areas where the buzz is noticeably worse in some areas than others, then you will benefit from a fret level, assuming you have enough height left in the frets to accommodate leveling (more below). Fret unevenness is caused by poor installation/leveling to begin with, wear, movement of the frets due to dimensional instability of the fretboard (which changes with fluctuations in humidity, assuming you have a wood fretboard), and other reasons. Fret leveling involves abrading the tops of the frets until they are all level with each other. The idea is to take down all of the high spots until they are even with the lowest spots. This can be done with abrasives or files, but as mentioned, there must be enough fret material left to allow you to remove some and still have enough left after leveling for the guitar to feel good. If there's not enough material for this, then a refret is required. New frets can usually be leveled once or twice, depending on their height. Some wire, such as Dunlop 6100 or 6105, is very tall, and will accommodate more levelings than shorter wire, such as Dunlop 6130 and 6230. At Acme, we level frets with a 24" long piece of 1" x 2" box-section steel that has had the 1" edges surface ground (a very precise method for flattening a surface). One of the edges was then coated with industrial diamond abrasive. Because the bar is long enough to contact all the frets simultaneously, and because the two skinny edges (one plain, one diamond-coated) are extremely flat, leveling is simply a process of marking the tops of all the frets with a marker, and then hogging away with the diamond-coated edge until the marker is removed from the tops of all the frets, indicating that the bar is making contact with every fret. This is an over-simplification, but is basically accurate. There are additional steps, such as adjusting the truss rod where we want it first (varies depending on the situation), and locking the neck in place to minimize deflection as we are hogging off the fret tops (a crucial step). One key point in our minds is the use of an abrasive device that is long enough to contact all the frets simultaneously, as opposed to using something shorter like a 10" mill file. The long bar is effectively surface grinding the tops of the frets, a proven technique for getting something flat (like some of the internals in your car's engine). Anyway, this removal of the high spots results in a neck where the tops of all the frets are level, flat (no longer rounded), and have big scratches on them (a problem); but we are going to talk about the next steps: crowning and polishing in the next article: “Fret Crowning How-to“. c2006 Barry Lewis FRET CROWNING HOW-TO When we left off last month, we had a neck where the tops of all the frets are level, flat (no longer rounded), and had big scratches on them (yikes!). If you played the guitar at this point, it would feel like the frets were made of sandpaper, so obviously this situation needs to be addressed. The fact that the frets are flat on top isn't good either. Assuming the frets are .050" - .100" wide, having them flat on top could alter the string length by .025" - .050", which is enough to throw off your intonation. Hmmm... does this require additional explanation? Yes? Okay, let's discuss scale length. Scale length is the length of the "vibrating portion" of your strings (from the fretboard-side of the nut to the saddle). On a Strat, this is 25.5 inches before intonation compensation. The width of each interval on the fingerboard is calculated based on this measurement, to 3 or 4 decimal places, using a logarithmic formula: 25.5 / 17.817 = 1.431" (width of first interval, or fret) 25.5 - 1.431 = 24.069 (remainder of scale) 24.069 / 17.817 = 1.351" (width of second interval, or fret) 24.069 - 1.351 = 22.718 (remainder of scale) 22.718 / 17.817 = 1.275" (width of third interval, or fret) 22.718 - 1.275 = 21.443 (remainder of scale) etc etc etc. Sleeping yet? The reason the fret placement is calculated so precisely (and the fret slots cut correspondingly precisely, at least on good guitars) is because you would hear if they weren't. The guitar would be out of tune to the degree that the fret placement was off. Even a small amount, like .025" (25 thousandths of an inch) would be noticeable, you would hear the notes beating against each other. Beating is that "throbbing" you sometimes hear between two notes, especially with distortion. The accurate fret placement is only effective if the top of the fret corresponds to the position of the slot itself. If the fret is round on top, the string makes contact in the middle of the fret, in line with the middle of the slot. Hog off the top of the fret so it is flat on top, and now the edge of the fret where the string "breaks" is off from the centerline by up to .050". As you move up the fretboard, this error is compounded because the .050" or whatever becomes a larger and larger percentage of the remaining string length. So it's important that the frets remain round on top. But our frets are flat on top. So we need to round them. We can do this with abrasives or files. The idea is to round the shoulders of each fret WITHOUT REMOVING ANY MATERIAL FROM THE TOP. Let's qualify this by saying that we are only concerned with the section down the middle of the top (where the strings will ultimately make contact), because we spent so much time leveling the tops last month. The last thing we want to do at this point is remove material from this section. The easiest way to do this consistently is with markers and crowning files. If we mark the tops of the frets with a marker, we can see at a glance if any material gets removed from them. Then we can use a crowning file to remove the shoulders (the square edges) while monitoring the marked tops to make sure that the marker is not removed down the center of the tops. A crowning file is one who's narrow edges have a groove milled or formed in them. This groove has teeth cut in it (or is coated with industrial diamond), so that it will leave a convex edge on a surface as it cuts. As the file is passed over a fret, this groove begins to knock off the corners, turning the top from a flat surface back to a rounded surface. Careful monitoring of the marked tops and an experienced hand will result in frets that have the merest sliver of marker remaining down the center of each fret, ensuring that they are nearly perfectly rounded, but that the tops are still level. c2006 Barry Lewis FRET POLISHING When we left off last time, we had finished leveling and crowning the frets. At this point, the tops of the frets would all be level with each other, and the tops would also be rounded (crowned). However, you'll recall that the initial leveling left the frets with scratches in their tops, and this would make the guitar uncomfortable to play, especially if you bend the strings. The guitar would feel all "scratchy". So at this point, we need to get the scratches out, and this step is typically called polishing. Here's how abrasives work: As you sand something, the abrasive particles scratch the surface you’re sanding. The sanding may make the surface "flat" (a relative term, as we shall see), but it also scratches it. If you sanded with 120 grit sandpaper, you would have relatively large scratches, and if you looked at a photomicrograph of the surface, you would see that it didn't look flat at all. The scratches would look like huge valleys. You would then follow up with the next grit, like maybe 220, and this would also scratch the surface, but because the abrasive particles are smaller, the scratches would be smaller than the 120 grit scratches. The idea with sanding is to obliterate the larger scratches from the previous grit with smaller scratches from the current grit. As you move up through the grits, each time completely obliterating the larger scratches from the previous grit, the scratches will get smaller and smaller with each successive grit until you can no longer see them with the naked eye. 2.
