Today, we continued with the task of building our two water filters. The long flat one’s frame is now constructed with a heavy thick metal bar around the perimeter and the metal mesh is welded on to it.

The second filter, the box shaped one, was tidied up, removing excess mesh material and it is now ready for the cloth geotextile fabric to be folded and inserted in.

Hopefully, tomorrow, we will get our new piece of the geotextile fabric (coming in the post) and we can wrap these two skeleton frameworks and then paint the metalwork in protective resin to stop rusting and also seal and hold the cloth in place.

We constructed a small test rig, to reflect the design and placement of the two layers of the wooden battens to be on our roof and then played with a dozen slate tiles.

The first row of any roof has to have two tiles (the lower tile is cut down in height) to ensure that the rainwater will be directed down the slate and not drip through onto the battens and the breathable membrane. We tested using the copper nails (through two holes) to see how they work, and tested using the hook nails (a bent rod of metal running underneath and hooks on the bottom edge)

It is quite obvious that there is a need for a “filler” to be inserted on the first batten, to take the place of the missing third tile, so we will fold up our gutter metal mesh guard several times to the required thickness and when that is nailed on the first batten row, that will provide the extra height needed.
The overhang distance of the bottom edge of the slate tiles will be about 55mm so we will position the first line of battens so that the tiles will hang over the gutters by 25mm, and the rainwater drips nicely in.

Sometime during the afternoon, we had the delivery of the remaining four pallets of our slates and they were unloaded alongside our Loke, following the line as we intended, but alas, one of the pallets was dumped on top of two others! We did not want this, as we wanted to be able to take […]

We continued to apply the Resin and Fibreglass layers to the Filter Parts. We completed all of the insides with their two layers as well as the two layers on the insides of the lids and side panel. The outsides of the filter will have a single layer of resin and fibre-glass as they will […]

We started today with the mammoth task of applying the protective waterproof layer and to provide the high strength structural element for our rain filter module. This is achieved by using layers of glass-fibre, coated in polyester resin, on all surfaces. The inside surfaces will have two layers of 450g glass matting (per square metre) […]
