KIT = Progress

Very busy measuring every single panel and timber spline in preparation for the build of the 9m roundhouse. 

The SIP panels are mostly cut okay though Tim Allan clearly can't cut  panel to reach 1mm accuracy. All the 24 roof panels are more like 4-6mm out in a crucial dimension.

Of the wall panels, we have discovered that one whole wall has the wrong window size opening and are having to work out what to do about that. This is a standard error in kit fabrication - the windows don't fit. Late last night I was checking the tolerances to see that we had enough space around each opening to fit the windows and discovered that we had a major problem. This means three new panels. 

I have had to recut about 50% of the splines for the walls but am now happy that 11/12 ths of the walls are within 2mm - only got to cut the rebate on one SIP panel now which had got missed out and get the new wall panels made up.

The hardest job will be making up the ringbeam that holds up the roof. Am about to get this started so watch this space.

The whole kit design is incredibly elegant in engineering terms. It is original and ground breaking, but the way it has been designed to fit together is so very neat.
