The launder is coming on nicely now, after Richard and others put in an extra day last Friday. You can see in the picture how far they had got, and more progress was made today. You can also see George in the background replacing the rail on the fence over the pit near the wheelhouse.
Peter and I continued preparing the larch boards for the launder, and brushing and painting the control lever for the gate valve.
The way the launder is being constructed can be seen here. The side beams are 50mm thick oak, with the joining pieces made of the same and bolted on. The bottom boards are 40mm thick larch, 40 inches long by about 10 inches wide (sorry about the mixed units, but those are the measurements that work!), rebated 20mm x 20mm along each long edge to give a stepped joint. The joints between boards and under the side beams are sealed with Roofer's Mate, which dries to a nice, inert, rubbery gasket. The boards are screwed from underneath using Screwfix M8 x 70mm Turbo Coach Screws. As you can also see in the picture, we have protected the core of the stone piers from any leakage water by reusing squares of the old plastic pond liner.
