Hi,
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).
The jig being used as a guide for the holes being drilled through the brass plates made. (P.076).
A photograph of the finished brass plates ready for tubes to be fitted. (P. 077).
The thread tube for connecting a union to and a copper pipe ready for hard soldering to the brass plate. (P.078).
The tubes and brass plate hard soldered together. (P.079).
The two finished plates and fittings. (P.080).
The pump water pipes connected using silicon tubes. Note a start has been made on fitting the reversing valve; this will be covered in the next exciting instalment of the Biscuit Tin Engine. (P.081)
To be continued….
