Nope, bottom block is fixed, top block is fixed right over it. Wire feed is
just in front of the top block. Board is held at two edges, there is nothing
above or below the board. Via taken to wire insertion, moved slightly to the
back so block corners catch it, knife cuts parallel to board and cuts against
top block. Once cut move back just a bit more to finish the top and bottom
bends, then on to the next via.
You need a diagram more than words, what I have in my head is very simple,
it'll obviously work..
