Just to clarify, you are lifting a weight with some acceleration a, and dropping it with the acceleration g. The hammer force difference is when g > a?
 And a can be minimized using the flywheel in this case.
This is an interesting idea, if I understood it correctly.

Hi, this is just a basic idea.  I have to measure how much electricity I can generate when the weights fall. Then I can replace the wiper motor with a pulse motor.

Hi, it seems to be working now. It needs improvement.

Are you making any headway with your project. Have been running back and forth offshore past few days. Don't have service 30 miles out, and too busy to post when around the dock.

Hi, it has been raining, waiting for dry weather.

Fabricated another manual PMA.

When you get back to your project you might consider changing wiper motor. It might make life easier to have a more powerful motor for cogwheel. Having the ability to change rpm across a wider range should speed up the tuning process.

I also believe that you will need to draw power from the pma at a constant rate. If you are charging caps and then discharging you will have a constantly changing load. This will make it impossible to maintain the timing of your cogwheel. As you know in order to get the max potential you will need all 5 weights falling while lifting 1. With a changing load you will have to increase and decrease rpm of wiper motor in order to maintain proper timing.

If your not already familiar with the formula this may be of help.
