Four Inch Pistons

After our last pump was built and tested and videos had been made, Jim and I put our heads together and after much thought and discussion it was agreed that four comes after three. So, we have built four inch pumps as you can see. Actually, the idea is to see if the forces involved with lifting water to a height of 25 feet with four inch pumps are greater than a 100 pound person can manage. The new pumps will be installed in the treadle frames shortly. We'll see how they work, and how hard it is to pump what we hope will be still larger quantities of water to the top of my rain gutter. I promise another video so you can see as well. The photo also shows the pistons and leather seals. One set has already been formed. The other is still just as it was cut.
