score it with a marking knife. Cut it shy of the line and then chisel to the line.?

Which way to present your work to the cutter?? I like your image
below because it? doesn't "Feel" as if it would? result in the
work being caught and hurled back at the operator but only?
experimentation can prove the theory. Different? species of lumber
may react differently too.
Which direction is the safest and/or best (regarding tear out) to
cut mitered bridal joints on the shaper? I will cut it in one go
with a tenon cutter. If I'd have to do this in two steps,, I'd
probably mess up some cuts due to the flipping and angle change
for the back side.
I need to cut this:

Should I angle the fence forward or backward 45 degrees? The image
below is what I mean with "forward". Feeding direction is down in
the image. The pieces are 400 mm long, so I'll have no problem
clamping them safely to the fence with a backer board. This is
probably the best way to minimise tear out, but I'd like to know
if this is an "unsafe on a shaper scenario". I realise that the
piece being sucked into the cutter is a potential danger. Clamping
is essential, and I'll also try to fit one of the Aigner fingers
between the cutters.
