Cutting a notching-out of straw bales
You will often have occasion to cut a piece out of a bale, as is the case when straw bales
are fitted around posts in infill construction. It will often be necessary to cut a hole in a
wall for plumbing and electrical work. For some time I was frustrated by the lack of
