The teeth should face so that the cut is on the pull stroke, not the
push. The blade is pulled tight during pulling, whereas it can all go
floppy during push. And any man knows thats a bad thing, and leads
only to frustration.

I assume you are talking about pad saws etc., with full frame hacksaws there
is not possibility of the blade going all 'floppy' on the forwards stroke,
assuming that the operator knows how to tension the blade correctly....

Whilst you are finding a clue about hacksaws you might also like to find a
clue about using Usenet correctly by getting yourself a proper news account
and stop using a archiving medium - http://www.individual.net/ might be a
good place to start on your search for a clue or two.

Depends on the job, normally forwards and outwards makes sawing easiest
as you're pushing forward and down, though yesterday I restored the
hacksaw back to this from the teeth pointing inside and forwards from
the previous job which was cutting pipes above head height, and have in
the past used them facing backwards if that was the easiest way to saw
in a particular location.

I've done it with a junior hacksaw, when I wanted to cut out from the back
of a fixed pipe. Space restrictions meant that holding the bow of the frame
and pulling out as I cut was about the only way to do it.

Nay, nay and thrice nay! Hacksaw teeth face away, so the cut is on the push
stroke. not the pull stroke. I think the only saws that might cut on the
pull stroke are some of those very expensive Japanese hand saws.

Alternatively, wander off to your workshop or garage, try cutting through a
piece of ¼ MS bar with a blade put in to cut on the pull stroke - you might
just be back in time for Christmas day.....

The opposite way to those of a wood saw.
That's about all I remember from O-Level Metalwork.

I'm pretty sure it's facing backwards, so cutting on the pull rather
than the push.

You didn't learn much then, nothing to be exact !..

Correct for a pad saw were pushing and cutting would result in the blade
bending.

You're probably thinking of a power hacksaw, which would probably cut
equally well either way round, but is traditionally arranged to cut
"backwards".

If I remember,
The reason for the teetth facing BACKWARDS is for the starting of the
cut. That is to say, you can not accurately start a cut on steel by
pushing the saw and definately cant start the cut pulling if the teeth
are forward facing, so, rear facing teeth enable an accurate start to
the cut, and the cutting is performed on the draw with cutting
efficiency increased by downward pressure of the fore-hand.

Now be a good fellow and find some refrences by saw blade manufacturers
that contradict the above and I'll let you off.

Makro do Japanese Shark pull saws for about 10/14 for the small/large
ones. Very nice when you get the hang of it, cuts fast and you can take
of very thin sections much more easily than with a conventional saw.

It's all in the wrist action ;-)

Is it your intention to answer every question with an insult? of just a
natural gift?

Perhaps it should be obvious that neither forward or backward is
"right", each have advantages in different situations, with different
materials.

Wrong so please return to your desk on the 9th floor and stop trying to tell
people who cut metal almost daily how to use a hacksaw !...

so, rear facing teeth enable an accurate start to
the cut, and the cutting is performed on the draw with cutting

Wrong, and if your O-level teacher told you that then he wasn't fit to sweep
the floor let alone teach !

No, you read the thread and then come up with a reference to prove everyone
else is wrong !

O - top of saw

It's just the way of things. The server I use is usually pretty good, but
things get held up sometimes and form a backlog.

I read off line and it is often the case that by time I log back on to

In normal use the teeth always point forwards

Well, tiz the time of the year foir this :-)

Bin a hands on engineer for nigh on forty years and I have never had a
floppy one 8-)
If you get a floppy when using a hacksaw, then you have not set up the job
correctly.

Just my 2 pennies worth.
