![]() ![]() Here is a closer view of the part that got badly damage. The milling speed was a bit fast so the milling bit ripped of some wood that I fixed by gluing. The guitar body is stuck to the wood with four taps which I hammered off to separate from the leftover. I had to put a 2.7 mm End Mill for the bridge screw holes. This is how the body looks like when we had finished the first tool path with 1/4 inches End Mill. I am using the pin method to move the guitar body when I need to mill the back.Īll the lengths can be seen in the Fusion 360 file which can be downloaded on the bottom of this page in Download Files. This is how it looks like in V-Carver Pro before the milling. I did the same for the fretboard which I was going to laser cut and then mill in the ShopBot. ![]() I saved the guitar as a STL file from Fusion360 and opened it in Inkscape and prepared it for VCarve Pro. The pine is not a good wood for a neck because it will probable bend, but I have ebony fingerboard that will keep it from bending as much. The adler is for the body and the pine for the neck. This is the wood I was going to use for the guitar, adler and pine. I didn't measure it I just assumed it would be enough. I made big space behind the guitar for all the electronic system. This is how the guitar should look like, without the bridge, pickups, strap buttons, tuning machines and the strings. I made five holes for the screw which are 2 mm each. This is how the plexiglass looks like when it's ready. Those are the holes for the LED light on the pickup holes on the plexiglass. Because the LED lights go through the holes and the cable also. The image below is of the pockets for the bridge which I extruded threw the guitar body. Each LED is 5x5 mm so the pocket is 5 mm and the board itself is 15x15 mm, so the bigger pocket is 15 mm. Those are the pockets for the LED lights in the plexiglass. I designed a pocket for the truss rod adjustment. I measured the trussrod and made a hole and extruded it. It should fit correctly on the sides but I had to add 2 mm on the top. Then I made a thin hole for the trussrod. This is how the guitar would look like with the bridge, pickup, pickup riser fret board and the plexiglass. I made the nut by creating a box and extrude it down and cut it. Here I'm making the bone, to see the distance between the guitar itself and the strings. On the image to the right I lowered the body down to 3 mm so the plexiglass wouldn't be too close the strings. Those are the measurements for the pickuphole and the bridge location for the screws, compare to the center of the neck. On Stewmac they explain the scale length as: I made holes for the tuning machines, but the ShopBot was not going to mill them because the headstock had 6 degree incline, it was more just to measure the lengths that I would later drill manually. Then I made a neck pocket by difference the neck from the guitar shape. I rotated the the headstock about 6 degrees and joined the neck and the headstock with a loft command. I used loft command to join the lower part of the neck to the upper part. Then I extruded the body up to 42 mm which is the thickness. Then I drew the neck in 2D and made curves on selected places and used loft command to make a 3D body. I changed some lines so the guitar would look better and center the neck and the body. I had to unlock the lines or else I couldn't move them. Then I saved the file as SVG and opened it in Fusion 360. You can see the scale length above the guitar, 635 mm. ![]() I also designed a guitar body and headstock in Inkscape and put them together to get some idea what I was going to do. I wrote the numbers I got from the fret position calculator and set the guidelines where each fret is located. Then I used Inkscape to draw the frets in right proportions. Then I used the Fret Calculator on Stewmac to calculate the fret position, which is the image to the right. On Stewmac they explain the scale lenght as:Ī guitar's scale length is calculated by measuring the distance from the front edge of the nut, where it butts against the end of the fingerboard, to the center of the 12th (octave) fret, then doubling that measurement. I decided to go with the Paul Reed Smith, 24 frets and scale length 635 mm (25"), which you can see on the bottom of the image below. I went to and found a list of common scale lengths. I wanted to make an electric guitar, so the first thing I did was to find a scale length.
