It was more difficult to load this video then it was to build the tsmo! Anyway, this is an out of tune 360 degree tsmo, and it is very hard to tune. Speed and balance is everything with this.Thinking of trying Chaklis's new design with this.It seems it would be unstoppable.It seems to be that springs of some sort are inevitable in these models, and/are the key item, but they are very hard to figure out . I don't like the wood construction steel seems better, but I really want to experiment around before building a nicer model. Next will be to try to add a similiar escapement like Ben Vandewaals over the top 360 http://www.youtube.com/watch?v=-5INHb5aXLo . I think it will help to make tuning easier and get real measurements.

Electric Motor Option for the GP210

An optional 1hp electric motor is available for the GP210 to allow hands-free operation of the water pump in areas where electricity is available.  In the following video, you'll see this option in action, and you'll also see how to quickly switch the configuration back to hand-operation via the GP210 pendulum.
