I know that is is possible to add a counter weight system, however I just try to keep KISS in mind. The only point I was making was that it is better to design something right. By knowing that even if you have no counter weight your transmission should still be able to work your arm. I have no say in what the kids want to do, if they want to have a counter weight that is fine it is my job to make sure they know what to do, and to answer their questions. This was just a fun side project based off of criteria that I set.
