I don't know if it's clear from the picture but six bricks above the arch have slipped down a bit - don't know if it was when I unblocked the thing or what. I'm now thinking I should put a lintel in instead of the arch. Pity - it looks kind-of nice like that, but I suppose it will be all plastered over anyhow when I'm done.
Can someone tell me how I work out the required size of the lintel? Width is 1230mm and there is only one brick skin at the front of the chimney. I've seen 1200mm lintels at wickes: http://www.wickes.co.uk/invt/244003, but how do I calculate the loading? There seems to be virtually no info with the lintels apart from a bunch of british standards, most of which seem to cost money! Am I supposed to just 'know' the details from those numbers?
thanks for any help,
