Day 111 - scaffolding erected
Friday, 30 July 2010
Today we are starting the next two timber ladder which will be located within the straw bales. We have constructed this jig to make it quicker. The rails of each ladder are fed in each side and the noggins (rungs) span between them. Two gaps in the jig opposite where the rung is located allow a nail to be fired using the nail gun to fix the noggin in place.

Once we have compressed the straw with ratchets we will put on permanent straps, which will go round the timber ladders. These need to be in place before we fix the first timber ladder down to the masonry. The straps are shown here, cut to length & ready to go.
The first straw ladder completed. It was not possible to use a nail gun on these as we needed 150mm fixings (nail gun limited is 90mm), so we decided to screw the timber together. The next ladders will use smaller timber sections, will be fixed with nail gun and do not need to be notched around the straps, so should be much quicker to construct.

The carpenters have moved onto constructing and fixing the rail (shown in red) and the bearers either side of the post under the rail (shown in blue).
The first ladder section completed and laid in situ. The added complication with this ladder is that it has to be cut around the holding down straps.
Next task to prepare for the straw is to start constructing the timber ladders which will go underneath and between the straw bales. The ladder under the straw (shown in red) will be constructed of ex.50x100, while the other ladders (shown in blue) will use 38x50mm. There will also be similar ladders on the first floor.
The ladders will be used to locate the ratchet straps around, in order to compress the bales. They will also be fixed to the timber posts which will tie the bales to the main timber frame.
As well as pointing the hazel using the axe and billhook, we also tried using the table saw. This was very quick!
We are now starting to get ready for putting in the straw. Hazel stakes will be banged into the bales from the third bale upwards to pin the bales together. These hazel sticks need to be halved and then pointed on one end.

Day 106 - the first frames go up
Sunday, 25 July 2010
With a mounting pile of frames at one end of the slab we need to clear some more space on the slab. Probably about 2/3 of the timber already moved out in this photo... we're on the home straight!

... by far the least effective method!
We also tried using an electric planer set up in a workmate - this was very quick but we decided it did not make a very satisfying noise and it was much more fun to employ one of the other methods...
We also started to put points on the end of the hazel stubs today. There are different methods we tried - axe...
Upper and lower levels complete on both sides. Now these need to be backfilled with top soil inbetween, and steps constructed in the centre. The tops also need to be trimmed to the right height.
