Mechanical Drawing Activity

Now that you know how to make a mechanical drawing that the machine shop can read, it is time to practice. You will be provided (or need to find) a simple part and reverse engineer it into a mechanical drawing for the shop. This is a common practice when you need to make a copy of a part to replace a broken part or to create a slightly modified design of some part on a piece of equipment. Use the necessary measuring tools to create a fully dimensioned drawing of your part, on a one-to-one scale if possible. Don’t forget to use any necessary center lines and to use good dimensioning style. Do not pick a difficult to draw cast part unless you really want a challenge! Brackets and simple lab jigs/fixtures are a good idea for your first try.
