Ok, this might sound simple to many of you guys, but it is really giving me
some headaches to find out.

What is the difference between Jack Plane and Bench Plane? I know jointer
plane is for smoothing the edge for jointing, but jack and bench???????

Thanks in advance.

Jack plane isn't a precise term, it just means a general purpose plane,
medium sized, normally longer than a smoothing plane but much shorter and
lighter than a jointing plane.

Tim w

lets try this by analogy

plane/automobile == jointer, smoother, molding plane chisel plane/SUV,
pickup, sedan, motorcycle
bench plane/car == (#7(jointer),#5(Jack),#4(Smoother)/station wagon,
sedan,hatchback
jack/mid-sized sedan == (Record #5/honda accord)

A bench plane is your every day basic plane design that comes in various
sizes. Bench planes are specifically not: specialty planes like a molding
plane. A "jack" simply refers to roughly the middle of that size range.

Not much. Both terms pretty much mean "general purpose". Shorter are the
smoothers, longer are the fore, trying and jointer planes.

Anyway, aren't all planes "bench planes" ? (barring a few specialists).
The whole distinction between joinery and carpentry has been described
as, "working pre-squared timber, on a bench, with a plane"

I know jointer

I'd say it was for straightening the edges, more than smoothing them. If
you're lucky a good jointer leaves a smooth edge too, but the important
thing is that it's straight. You can smooth a straight edge, but you
can't straighten a smooth edge without wasting the smoothing work.

A picture is worth a thousand words. Go to Leevalley.com and look up
Veritas bench planes.

my understading was bevel down=bench plane; bevel up=block plane (regardless
of size).

This is the way LN labels them on their site and, frankly, that makes it
good enough for me.
by the way, the block planes on their site include low angle jack, iron
mitre and low angle jointer, so apparently block plane is not just a 'size'
of a plane.

"Bench plane" refers to specific group of planes; For Bailey type planes,
these would be the # 1,2,3,4,5,6,7, & 8, the fractional sizes in this
same range like the 4 1/2 or 5 1/4, and some would say rabbet planes of
the same pattern such as the #10. It does not include other planes even
though they are often used on a bench, such as shoulder planes,
block planes, and other rabbet planes like the #78.

Of course, this is a somewhat informal term and others may have
different definitions, but this is what I have seen in the literature
and in general usage.

Lee Valley broke the rules. They list bevel up smoother planes as a bench
plane. The only general characteristic I see for a bench plane is that it
has a knob style front handle and a pistol grip style rear handle and its a
design derived from Stanley.

That brings up another question. Why do some planes, most notably a
block plane, have a bevel up while others have it down?

Tis a puzzlement !!

I don't know if my way of thinking is right or not. But I guess most
block planes have a low iron to bed bottom angle, in this case, it would
be difficult or taking too much work to hone the blade if the bevel is
down (it would take a lot of iron material to make a sharp edge and a too
thin edge not to damage it easily).

Just my 2 cents.

Anyway, thanks a lot for all the informations shared here. At least I
know the general idea of the plane's naming.

Jo

It shifts the effective angle between the iron and the timber. Putting
the bevel up is equivalent to making the frog 25° steeper. OTOH, bevel
up also gives the opportunity for support from beneath that's closer to
the edge.
