I take a moment to do the grunt work…
Well I now have everything situated, but I want to get the pickguard correct, so while it’s unfinished, I mist a piece of craft paper with spray adhesive… give it a good while to dry to a semi tacky state and stick it down..
Using “Landmarks” from the photo, I note the angles of various points in the photos, and make corresponding reference marks on the craft paper.
Then I will sketch, and erase, and re draw… I’ll step away for a break so I come back with another perspective, sketch and erase and re draw, until I’m pretty happy that it looks pretty close.
I now have to locate the control knobs, using the photo; I can determine that a line drawn through the three knobs centers will intersect the neck at about the 17th fret…
Therefore I locate my straightedge on the 17th fret, and estimate the location relative to the F hole and make a line…
