Grind the points separately, in a horizontal position, by rubbing them on a whetstone Hold the points vertically together and grind them lightly by drawing them back and forth against  a  whetstone Grind  the  points  separately,  in  a horizontal position, by twirling them  against  a  whetstone Replace  the  needlepoints 2-38. 2-39. In what way, if any, should the needles of compasses and dividers compare  in  point  size? 1. Those of the compass should be slightly  larger 2. Those of the compass should be slightly  smaller 3. They should be the same size 4. None; the size does not matter Which of the following methods . should you use to protect drawing instruments  against  corrosion? 1. Clean them with a soft cloth and coat them with a light film of oil 2. Polish them occasionally with metal polish 3. Clean them often with a chemical provided by the manufacturer of the  instrument 4. Rub them lightly with emery paper and apply a light film of oil IN  ANSWERING  QUESTIONS  2-40  THROUGH  2-44, SELECT THE DRAFTING INSTRUMENT FROM THE FOLLOWING LIST THAT SHOULD BE USED TO PERFORM THE DRAWING TASK LISTED. 2-40. 2-41. 2-42. 2-43.
