Tighten the screws and do not forget to set the tracking force and anti-skating back to the weight specified for your stylus. Repeat until the cartridge is correctly aligned on both grids. If the cartridge is at an angle here, adjust the overhang according to the following illustrations: Lift the tonearm and move the protractor to place the stylus on the inner grid’s center point. Then check the cartridge alignment on the inner grid. If the front is flat, taping a pencil lead to it will help to make a more precise adjustment. Lift the tonearm and adjust the cartridge’s angle until its front is parallel with the grid. Set the stylus precisely onto the outer grid’s center point. Loosen the screws that hold the cartridge in place just enough so it can be moved, but cannot move by itself. Place the alignment protractor on your turntable, set anti skating to zero and the vertical tracking force to a lower weight than you would normally use with your stylus. If it is not, scale the template by changing the printer correction factor.Ĭut out the protractor and make sure to punch or cut the hole as precisely as possible. Measure the outer rectangle to be sure it is exactly 190 mm long. Please make sure to print out the alignment template at 100 % scale (to be set in the printing dialogue of your browser or operating system). You may also laminate the cartridge alignment protractor. Alternatively, a piece of clear packing tape stuck onto the target points will do the trick as well. It is recommended to print the 2-point protractor onto glossy photo paper to protect your stylus. The pre-set values should be fine for most users. If you have no idea about the technical intricacies of turntable geometry, do not worry. Please note that the resulting overhang and offset angle may be different from the stock specification chosen by the record player manufacturer. The measurement worksheet will produce two problems per. The 2-point protractor will still allow you to set the overhang precisely for your turntable, according to the chosen alignment geometry. This Measurement Worksheet is great for practicing reading and using a protractor to measure angles. They are not as easy to use as arc protractors, but knowing the exact pivot to spindle distance of your turntable will not be necessary.
Flip the folded paper over and place the edge of the paper on the 90 degree angle of your protractor.2-point protractors are universal protractors for turntable cartridge alignment that can be used with any record player (as long as the slots in the headshell are long enough for the alignment geometry you choose).The corner of the triangle will be slightly to the right of the center of the paper and an imaginary line extends from the corner of the paper to the bottom center of the paper.
