drawing esp-style headstock

define the string spacing (1.5") & define the upper and lower overhangs (5/32", 5/32")
starting from the line defining the nut which is considered (5/32 + 1.5 + 5/32) x 0.25" thick locate the point/position of the first tuner by drawing from the center a line of the nut a perpendicular line 1.75" then a line to the orientation/position of the tuner (left side) 1.125" or 1 1/8" which is the location of the tuner .. from this point at angle (63.25 degrees) draw a line (15/16)x5 there will be the rest 5 tuners and thus the 6th tuner is located .. from the 1st and 6th tuner draw the upper part of the head stock by drawing a line from the two point at 90 degrees of length (15/32") and there for we get two points over the 1st & 6th tuners (edge of headstock) and from the 1st point (at the left bottom of the headstock) draw a line 9/16" and from the 6th tuner (at the upper left of the headstock) a line 1.75" and from the last line drawn draw a line of 1.75" at angle 75.5 degrees so the head of the head stock is draw .. then tere are two 3-point curves one starting from the left point of the line of the nut to where the line at the left-down of the headstock ends and the other curve is at the right side of the headstock from the right point of the line defining the overhang at the nut to the end of the line having angle 75.5 degrees

to complete the neck (single scale, not multi-scale), define the scale example 26.5" and for that value from the center of the nut draw downwards a line at 90 degrees 26.5" at that point the bridge is defined .. define the string spacing at the bridge (example 2.125" or 2 1/8") and define the overhang at the lower and highest strings - for example (7/32", 7/32") connect the lines (the overhang of nut to that of the bridge) 
locate the position of the last fret from the nut example the 24th fret (19 7/8"), for wheel-nut truss rode (nut at the heel) add 3/8" so the size of the neck and the fretboard is determined

to draw the right big curve in this example, from the center of the line representing the nut draw a perpendicular to it a line of length 3" and then toward the right a line 1.218750" or (1 7/32") so the points of the 3-point cure tool are available and located .. draw the curve from the point at the right end of the nut to the point at the 1.75" line at the most right of the headstock then define the curve by the 3rd point lastly located (3",1.218750") .. as an option, instead of (1 7/32") take it as ((1 7/32") - 1/64" = 13/64") .. it's about decision as one would like or prefer

to draw the left small curve in this example, from the center of the line representing the nut draw a perpendicular to it a line of length 1" and then toward the right a line 1.218750" or (1 7/32") so the points of the 3-point cure tool are available and located .. draw the curve from the point at the right end of the nut to the point at the 1.75" line at the most right of the headstock then define the curve by the 3rd point lastly located (1",1.218750") but to avoid line/curve interference start the curve not at the nut but add 1/8" above it 'on the y-axis' to be the first point of the 3-point curve .. as an option, instead of (1 7/32") take it as ((1 7/32") + 1/64" = 15/64") .. it's about decision as one would like or prefer .. in case of taking it as ((1 7/32") + 1/64" = 15/64") there would be no need to start the point of the curve above the nut by 1/8"; however start it from the left point of the nut 

in this example the headstock is almost centered sits within the margins of (7 7/8" x 3 5/8") there's a gap between the most right point of the headstock and the margin at right of 0.020410" less than 1/32" and there's a gap between the most left point of the headstock and the margin at the left of 0.015736" a little more than 1/64"
