The plane is 14 inches long. Should it be bevel up or down?

If you look at the blade (referred to as the 'iron') in the picture
shown in the above reference, you'll see that the ground edge is
horizontal when the blade is installed. That tells you which way round
it has to go.

That's an interesting observation, but I think it's a wrong one.

Why do you think it's wrong?

I haven't got a wooden plane, but I've just had a look at my metal
plane. The ground edge is definitely facing down so as to be
horizontal-ish. It wouldn't work the other way because the cap iron
(chip-breaker) needs to face a flat surface. See
https://en.wikipedia.org/wiki/Plane_...plane_iron.jpg

Only because the iron is set into the plane on my general purpose planes
at something steeper than 45dg so a 30deg honing angle on the downward
facing bevel still leaves 20-30degrees off horizontal.
Here https://en.wikipedia.org/wiki/File:Plane_parts.jpg the smoother at
around 45deg plus but the block plane gets a very low angle of attack by
being bevel up.

Now I think about it I am not sure I understand the difference.
