Hi All.
I was exhibiting my latest completed project at the Furness Model Railway Show last weekend 12th and 13th. This was another of my real water models, Hirstwood Lock No 19. Also showing it at the Blackpool Model Boat Show next weekend. This a model of a narrow canal lock..It is one of those models I had to have a go at to see if it could be done. I had originally looked at a broad canal but at the planning stage realised it would have to be narrow canal. I came up with an optimum length of around four feet, In the end the length was decided by the longest garden tray I could find which was 44 and 1/2 inches long. The model is 43 and 1/2 inches long. The scale is 1/8 inch to the foot. The garden tray was to act, in cricketing terms, as a long stop if there should be any leaks while at a show! A simple drawing was made re the main dimensions but it was built on the sort it as you go along method. Plasticard is the material used as it is waterproof. I'm not going into in depth construction as I'm sure it would descend into being incoherent, Most narrow canal locks have a single top gate and double bottom gates. In such a small scale this poses a problem However as part of my research I had gone on the Huddersfield Narrow Canal site and there are eight locks between Wool Road and Diggle that have a single bottom gate. Problem solved. As with real locks my gates do dribble but so do most real locks. Waterproofing of the gate is helped with a thin smear of Vaseline round the edges of the gates. On the real thing water runs in a continuous flow from the summit pool. On the model I have a plastic container in which a small pump feeds the upper pool and as per the real thing.excess water goes down the by wash to the lower pool. When the water level in the lower pool is full water runs back by gravity to the plastic container. Not prototipical but it gives a continuous flow of water There are three narrow boats, once again all plasticard except for a lead strip "keel". They are not motorised as they are too small to fit motors and batteries. Propulsion is by means means of a hand held twizzle stick. It performed very well over the weekend at it's first show. Further model shows are Kendal , Narrow Gauge North and York..
Cheers. Derek
