Pump it up!

Meanwhile, Ned and Pat have been doing an awesome job figuring out the positive displacement pump. The photos below show final construction of the pump. Unfortunately, we are yet to successfully get the pump to work using the step motor to rotate the axel. We were able to use the pump with a drill connected to the axel, so we came to the conclusion that the step motor just isn’t powerful enough. We will continue to try and make the pump have less friction so it can pump more freely.
