We continued with the task of slicing up the wider rolls (four of them) into a little bit narrower width (380mm because we are using narrower slates than we envisaged months ago when we bought the rubber), using our dispenser with the razor blade as the cutting tool. But we discovered that the rubber material had too much flex in it to keep it straight and it wobbled side to side and made a ragged edge, especially after pulling out longer pieces. So we had a think .. and decided to replace the razor blade attachment with a battery powered scissors instead.

It worked much better but it was still awkward in trying to handle the rubber material and we ended up getting a third pair of hands to help to help roll up the cut rubber – we needed 1 person to unroll (the rubber is firmly ‘stuck’ on the roll) and 2 to re-roll (1 for each strip).
We now have a trug full of 15 lengths of rubber strips, for the hips and ridges, alongside another 2 trugs of similar pieces but for the guttering.

So that’s that job done so everything was dismantled and we started making the next dispenser, this time for the roll of the metal mesh. This metal mesh is for covering the gutters to keep out large items like leaves, moss and other rubbish blown on the wind.
The mesh is a grid with 5mm spacings and the roll (being 920mm wide) will be chopped up into 300mm lengths and we are planning to use a guillotine like mechanism to cut the mesh. We will find out later on whether it will work or not .. time will tell!

Today, we made a dispenser to hold a roll of rubber membrane (20m long strips 500mm wide wrapped on a cardboard tube) so we could easily unroll each roll of rubber and cut them to the required lengths. We had a list of 16 numbers, optimised to minimise wastage off these 20m rolls.

We now have a pile of cut pieces ranging from 1.4m to 10.2m long, ready to be inserted into the guttering when we get to assemble each section around the house.
We then modified the dispenser by adding a cutting module, positioned at 380mm from one edge so we can produce a narrower strip of rubber for protecting the hip and ridge lines. The cutting module was made by sandwiching a classic razor blade in between two strip of battens and then screwed down to the upper layer of the cement board.

Even a razor blade struggled to cut the rubber membrane when we tried to slide it through the thin slot. But we realised that if one manually cut a short distance first, it started slicing fairly easily afterwards.
On Monday, we will slice the remaining four rolls and cut a further 15 lengths (10 hips, 5 ridges).

We took the opportunity yesterday and this morning, to install two LED flood lights up inside our house. Each 300W unit was fixed right in the roof, just under our skylight on each narrow end section, pointing towards each other and downwards. We put a waterproof switch beside the Side Door entrance and ran the […]

Whilst planning the slating of the roof we found we needed to attach the guttering to each roof section before anything else because it is the lowest part of the roof and everything else ‘flows’ into it. But if we install the gutter we need somewhere for the water to go so we have to […]

Today, we took the opportunity of the fine sunny but cold weather to take our Lift Shaft outside and install it against the walkway platform running around the back of the building. It was positioned against the start of the “I” section of the roof, mounted on a 8feet by 4feet sheet plywood. We also […]

Today, we created the Lift Shaft to take our box on wire up and down. It measures 730mm by 760mm (internal measurement of 680mm square, the size of the cargo cage) and it is nearly 5metres (16feet) long, or rather tall when it is standing up. We also created the support framework to hold the […]
