| Auto guys will then make up a bobweight of nuts and bolts equal to the rotating part which they add to the crank throws and that is then spun on a dynamic balance machine. |
| The bobweight we use is usually somewhat heavier than the final bobweight of the finished rotating assembly. |
| A good rule of thumb is to figure a bobweight of 2400 grams for these motors as it will almost always balance out a bit less than that. |
| The program available here is the first part of that project, in that it helps to compute the bobweight masses. |
| A simple cord pendulum with adjustable bobweight is included. |
| Finally, the bobweight is attached to the rod pin and the complete assembly is spun and dynamically balanced. |
