Another universal protractor, this time using the Stevenson alignment method with null points at This is especially useful for arms which have limited room in the headshell slots and can't be aligned satisfactorily with a Baerwald type.

Sorry about this stupid question. Where do I need to measure the nul points from, if I want to make my own protractor? Is it from the spindle or somewhere else? So if I make a allignment protractor, I need to measure the nulpoints and then draw line between these points, after this I need to draw lines perpendicular from this line outwards? Did I get it right?

Then measure from this centre line the two null point distances and draw two lines at 90 degrees - these will be the two points at which you will place the stylus to check tangency.

If you have Illustrator or a CAD program it's easier as you can more accurately draw the lines and maybe add a grid. Alternatively you could download the Chpratz Protractor above but it is only accurate to 1mm so you would be looking for alignment at the 69 and mm lines. Obviously using 15mm overhang and Linear Offset technique with only one 66mm nul point gave me a right cartridge allignment.
