Tried out my new toy today - a hand-held jigsaw (as at
http://s7ondemand4.scene7.com/is/servlet/izoom/BandQ/5397007003154_001c_v001_zp?&$230x230_generic$
). Trouble is, it doesn't cut straight. I find that I have to hold it
at about 20degrees off the marked line (in a clockwise direction) in
order to get it to cut in the right place. I've tried loosening my grip
and also ensured that the sole plate was properly down on the work piece
(which was laminate-faced chipboard about 15mm thick).
Is it a technique thing? If so, what am I doing wrong? If not, is the
thing defective, and how would I confirm that?

Fresh blade. First circular cut dulls the blade on one side, making
it lead.

Henry, congrats on your new toy. These aren't the sturdiest machines,
and it could be the machine is at fault. But a couple of things to
consider. As pointed out above, make sure you have a quality blade
on the machine. Those little stamped gizmo blades are almost of no
value at all. I use this rule for a wood cutting blade: you should
be able to easily prick your finger on the blade. If you can't, buy a
better blade.
Try the "swiss filed" type of blades for the saw. The laminated chip
board can be tough on blades since the resin in the laminate will get
soft and clog up your blades if it starts to get hot (which cheap
blades do).
Also, the hotter the blade gets, the more it will wander.
Worse, some of those blades are of such low quality they flex in the
saw, and then you are totally screwed.
For something like that (oatmeal grade chipboard laminated with
plastic) I use the 5-6 tooth swiss file Bosch blades. These cute
quite well, last a reasonable amount of time, and won't give you a
rough cut.
This evening I cut five poker table tops (36" X 95") out of 3/4 birch
ply and10 build up trim rings of mdf with my Bosch using these blades,
and only used three!
Don't push the saw. Lower powered saws overload easily, and make good
cutting almost impossible.
To see if it is you or the saw, try this:
Get a good, sharp blade. (See above). Put a straight line on a piece
of your laminate board, and try cutting just a straight line, no
curves. If it cuts at ninety degrees in a straight line, then you are
set as you know it was probably the blade. If it is still at 20
degrees, take the saw back and let go of some more dough.
If it does cut straight along the line, try a gentle curve. Still
straight? Looking more like the blade all the time. a few degrees of
slant? Probably technique. You may need to slow down with the saw,
or speed up the blade.
Like anything else, it take some practice.
Good luck!
Oh yeah, don't get discouraged when someone trashes your tools or
ideas around here. Like any other group, sometimes the peckerheads
are the loudest. There are plenty of good folks and plenty of great
info here.

... and numerous others wrote good stuff too. Thank you all (with the
possible exception of Andy Dingley, whose contribution wasn't worth a
lot). I'll make sure the blades are good, and the right ones for the
job, and practice. But I'm getting the message that a jig saw isn't
good for long straight cuts; I guess I'll still be using my hand saws
for a while yet!

Why is that? As an empirical observation, few would disagree with
it. But _why_ ?
What's so special about jigsaws? Is there a particular component
that's not doing its bit? How do you tell a good one from a bad one?
I'm assuming it's the blade guides more than anything (as a total
guess). So what's a good design of guide that works, and what doesn't?
I think this is a pretty subjective statement - as someone who got
scared away from cheap equipment by my craftsman router and a now
twisted bit, I would've said the same thing about routers.

So, you bought a crap jigsaw. Most of them are.
That's why every time there's a jigsaw thread hee or in uk.d-i-y,
there's a chorus of people saying to spend the money and get a Bosch
barrel body or maybe a Makita.
You buy crap tools - they work badly. QED.

Seconded, I would love a decent jigsaw. I use my crappy B&D for stuff I
don't care about or I cut to leave the line and expect to have to clean
up afterwards. I also bought a coping saw and taught myself how to use
it, and a bearing guided straight cutter for the router so I can make
ONE pattern in something like hardboard, use the jigsaw to leave the
line then the router to make exact copies.
For straight cuts I generally use a decent handsaw then clean up with a
plane. Good for the arm muscles.

I suspect it is partly how robust the units are, which can at base
reduce vibration which in a jigsaw will make it wander. I have almost
given up using my B&D circular saw as the motor is so heavy wrt the
baseplate with most of that weight lateral that it almost never cuts
square as the join between the baseplate and the motor flexes. It is
actually worse if you set the depth of cut apropriately. Of course at
the time I bought it....

Agreed, the way to go with routers on a budget is to put your money into
good bits. A crap bit in an expensive router will still give crap
results.

*snip*
It's one of the few common tools that relies on the motor to produce an
up and down motion rather than just spinning a bit or a blade. More
parts = less tolerance.
That's my guess anyway. Anyone here familiar with scroll saws enough to
say if this may hold true?

FWIW, I do all of my rough outs of sheet stock with a straight edge
and a Bosch jigsaw. With good tools and decent technique, it can work
out quite well!

Because it is flawed empiricism ... a trip to any Harbor Freight will

Henry,
First order of business, does the blade you are using match the
material being cut. Just like any saw, there is a correct blade for the
material. If that is ok, then see if there is a stroke adjustment for the
blade. This alters the amount of forward stroke of the blade each time a cut
is made. This can be affected by blade used and the material being cut.
Sometime you just have to play with the amount of stroke to get a better
cut. And, yes ALL jig saws wander. They are really made for following odds
shaped cuts rather than straight cuts. I have used my circular saw to cut
the straight sections, leaving the odd shapes to the jigsaw. However I have
found after trying several others, the Bosch does seems to cut straighter
than the other yellow jigsaw I have. Lastly if you do choose to use the
jigsaw to make straight cuts, use a fence to guide the saw and the slower
the you move the saw forward the better your control. Good Luck

Well, Andrew me lad, you consistently show that your awareness of issues is
insufficient to make judgments based on observation and experience, and the

If it is, it's a commony held one.
I'd never advocate spending big money on a cordless drill, rarely for
circular saws or sanders, but always for jigsaws. A cheap jigsaw --
every cheap jigsaw -- is tirign to use and performs poorly compared to a
good one.

Cheap routers are often unpleasant to use and sometimes downright

Yes it was.
I'm not aware of any tool where the difference in quality

Well, if you've gotten a good inexpensive jigsaw at HF, then good for you.
The way to be useful and helpful to other woodworkers would be, for example,

And you might want to find out what "empiricism" means before you use it.

I have never opened one up but I would say that the difference is
counterbalancing. Converting a rotary motion to linear motion is common.
Think about an engine crankshaft. The crank has counterbalance lobes to
smooth vibration. Same principal would apply to a jigsaw.

Do you have a router?
Before I had access to a table saw, made proud cuts with a saber (jig)
saw, then cleaned them up with a router and a straight edge.

I'm not saying it's not possible, it's just not made for it. You can
do all of your cuts with a scrollsaw too if you're really slow and
careful but that's really not what a scrollsaw is for.

No, jigsaws are for short cuts, usually curved or oddly shaped. If
you want long, straight cuts and don't have a tablesaw, get a circular
saw and a straight-edge. You just can't get that very well from a
jigsaw.
