Dynamic balancing wheels or flywheels via the web

How to dynamically balance a wheel or flywheel via the internet.

Safety first: Be sure to observe all normal safety precautions. Operate at safe speeds. Do not allow weights to fly off of the wheel. No loose clothing. Check the integrity of the wheel. Etc. 

1) Mark 3 approximately equally spaced locations for weights on the rim of the flywheel. Label the counterweight locations 1, 2 and 3 (in any order). Prepare ~20 counter weights of approximately equal weight.

2) Click the button above and attach counterweights with the quantities shown in the first line in the dialog. Count carefully and make sure the weights go in the proper locations. Do not use more than 10 weights at any one of the three locations.

3) Spin the flywheel. Each time you spin during balancing, spin at approximately the same speed.

4) Rate the wobble on a scale of 0 (none) to 9 or more (much). The unit of your scale of wobble is not important but consistency between each test is important. Make sure you estimate the amount of wobble as accurately as possible.

5) Enter your wobble rating in the blue box and click the Balance button. Repeat from step 2 until you find the minimum wobble. It usually takes about 10 to 15 cycles thru the steps to complete the balancing. If the changes in weights are more than one after 15 cycles, stop, re-read these instructions carefully and then continue where you left off (or start over).

Dynamic Balancing Flywheel Tips

You can also dynamically balance using the  honeycomb map. Try random counterweight configurations - the 3 digits correspond to the number of weights at locations 1, 2, and 3. Print the map and mark the amount of wobble for each combination on paper. Gradually zero in on the best area of the map to explore for the least wobble.

If you don't feel you can assess wobble accurately enough by feel or listening, affix a small mirror to the center of the flywheel or wheel and bounce a laser pointer onto a wall. Go by the size of the circle. Follow the precautions that come with the laser. Or use any other means of measuring the amount of wobble.
