To understand how to make guitars and guitar-type instruments, you only need to grasp a few basic facts. Taking a look at things simply to start with, how to make a guitar all can be logically understood by dissecting the instrument into three major parts; you have the body, which can be hollow, or solid in the matter of an electric guitar; there is the neck, which both supports the strings taught in addition to provides a place for fingers to press the strings against (at different places, effectively shortening the length of the vibrations thereof, to varying degrees), for creating different notes; and there are also the strings themselves. Let's take a closer look at the first 2... - Jadakiss Type Beat 2016
Before we get into the math involved in fret placement, if you're searching to know how to make guitar necks like those we see on guitars in instrument shops, particularly with those electric types who use steel strings, you may invariably need to route a channel (usually within the fret board, before attaching it) centrally around the length of it for a truss rod to be saved in place. A truss rod is employed to correct any natural bowing that may occur in the wood from the neck, or which can also be due to the stresses of stretching steel strings upon it, by adjusting the strain thereof.
Understanding how to make a guitar neck for acoustic types and the ones using nylon or another material for strings, we find that this may not be necessary. Having a slight arc to the fret board through the cross section of the neck might be desired, based upon the player's specific needs - with this aspect of how to make guitar necks, you will find that these can be of different radii, like with the Gibson type guitar fret boards, which may be of a 12" radius arc.
Making guitar fret placements over the length of the neck become known takes a wee bit of math - somewhat trick known as the "18 rule". The 18 rule is often a means of finding precisely where you can place each fret about the fret board, which is a must-have bit of information, in the event you really want to know how to come up with a guitar. It goes like this; you measure the distance in the "effective length" of the string... this means, the part of the string that lies freely between your "nut" at the head stock end from the neck (also called the "zero fret"), as well as the "bridge" at the body end from the strings.
You then take this measurement and divide by 18 - or far more precisely, 17.8167942... consider the answer to that math problem, and you have the precise distance through the nut to place the initial fret. Now measure from that unprecedented first fret placement along with the bridge, divide that by 17.8167942, and you then have precisely where you should put the next fret, and so on. The number 17.8167942 is pretty close to 18, thus the particular rule.
There are other factors in learning how to make guitar type instruments, but none of them that are quite as mathematically involved as finding fret placements a lot. Now that you know the 18 rule, you have got the hardest mathematical part in your memory. So as you can see, finding out how to make a guitar and putting one together doesn't have to be very difficult. The rest is a matter of how well you work with your hands and what tools you've at your disposal. With strings, fret wire, machine heads and wood clamps and the like, readily available and easily enough bought, it's all regulated easy enough to put together when you're conscious of how. - Jadakiss Type Beat 2016
