Leeds and Northrup Galvanometer (Mad Max, Doof Warrior)

thingiverse

Part of Coma's (Doof Warrior's aka flamethrower guitar guy's) guitar. These are Leeds and Northrup galvanometers, modeled from high-resolution pictures found online. Coma has 2 of these on his guitar. I kept some parts separate for ease of finishing/painting. You can also print the combined version in one shot. I provide a sheet of dial graphics as SVG. There are 100%, 98%, and 102% scale dials in multiple copies so you can easily find one that fits (paper printers can be inaccurate). I also provide plain white background and brown background versions. I used the plain white background and just dribbled some coffee on it to make it look old. There is also a calibration bar, 3" by 0.25" so you can see how accurate your paper printer is. The dial pointer can be left out, but I just glued a random piece of discarded print skirt in there because it was a thin piece of plastic already. Painted the tip red. Remember the pivot point is close to the big knob in the real version. I didn't bother modeling the text on the knob. I finished this in plain black spray paint and antique gold rub'n'buff on the little nub thing. Plain acrylic wash and abuse with a file for weathering. I also cut out a piece of acrylic for the window. To do this I spray glued (elmer's) one of the dial templates onto a piece of acrylic and shaped to fit on the belt sander. WD-40 easily removes the adhesive afterwards.
