![]() ![]() An angle in geometry is when two lines meet and share the same point. It is easier with a full circle protractor than using a half-circle protractor. You can use a half-circle protractor that has a 180-degree chart or full circle protractor that has a 360-degree chart. It will really help you to draw an angle. People usually use a tool called a protractor to measure and draw an angle.Don't forget to attach pencils to your drawing compass and be careful with the compass needle. With a drawing compass, you can make a nearly perfect circle. Be sure the items you use fit on your paper and have a smooth edge to make it easy to trace. You can use many items like the bottom of a coke can or round glass. Using round shaped items and trace it.There are so many ways to draw a circle like: Tighten the screws and do not forget to set the tracking force and anti-skating back to the weight specified for your stylus.A circle is a figure that has a round shape with no corners and edges. 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 2-point protractor will still allow you to set the overhang precisely for your turntable, according to the chosen alignment geometry. 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. 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). ![]()
