As promised in the previous posting a short video of the water pump in operation. The pump works quite well and is self-priming. It would probably work a little better if the pump ram went into the space between the two valves. Possibly at a later date a new longer ram might be tried. (P.073)

With the water pump finished a means of getting the water into and out of the engines wooden base was needed. A mild steel jig was made to drill the holes in the wooden base. Photograph shows the jig being used to drill holes through the wooden base. (P.074).

Photograph, using the same jig as a filing jig for the brass plates that will hold the copper tubes that will go through the wooden base. (P.075).
