Starting in November, I've got a fairly large hardwood thinning job to do (circa 400 tonnes), comprising of mostly ash and beech. The owners of the woodland would like a very tidy finish and have asked for all branchwood to be chipped.    I don't own a chipper, and I don't really want to own one if possible. However, I've always liked the idea of branch loggers as a means of producing a low grade, cheap wood fuel. I realise that the product is quite bitty and not favoured by everyone,
