Lack of accuracy of cuts performed by B&Q on their panel saws

Doing a shelving job in an alcove for a relative well off my usual
turf. I called into a local B&Q (an act of desperation I know) and
had some plywood cut into strips so I could easily transport it to
site where I could cut it into rectangular/ trapezoidal pieces on a
sliding compound mitre saw.

I wanted one strip 300 wide and four strips 200 wide running the full
length of the sheet.

Seeing them actually cut the stuff they only made two set ups. I left
my tape in the car so couldn't check the accuracy of the cuts in the
store.

The 300 cut was a couple of mm over, probably a basic misunderstanding
of kerf, but the 200 strips were even more out - I had two strips at
205mm and two at **225mm**

How the hell can they cut 25mm oversize while keeping the same bloody
setup? That's the best part of an afternoon wasted.

Useless f*ckers. I could cut more accurately with a blunt axe.

Practice!

Never tried there board cutting it has to be said. However with the
snazzy panel saws they usually have, its surprising they can get it that
wrong.

(small cordless circular saw and a couple of folding trestles would
probably do a better job, not only that you can leave the sawdust in
their car park ;-)

I'd guess they didn't clamp the stop/fence firmly. Slide up the board
first time, knock the stop over a little. Second time, knock it even
further.

I've used the board cutting before though not for ages since we moved
house, and I've always found them pretty accurate.

They must have mess up the clamping or something so something could
move?

But you didn't notice that two of the four that should have been the
same width were significantly different?

or 20mm different to previous cuts. That sort of size has the feel of
being on top of a stop/clamp rather than behind it or somthing like
that

Until the stop breaks and can no longer be locked at all.

I think it depends who is on the machine that day. Our local Homebase
offers a cutting service, and if the old deaf guy is doing it, it's
spot on. Even accounts for the 5mm the machine eats.

Cheers,
David.

That's good service.

I don't usually assume that will happen in my place, but I do tell them I
want certain cuts to be repeated exactly sometimes and they do manage that.

I either just get it cut a little oversized, for transport then trim it down
a bit myself, or I'm doing a project where +/- 5mm doesn't matter as long as
they are all the same.

The sheds here scatter them on racks all over the place - I often grab
one on the way in to use and return it on the way out.

Having said that, the shed that I normally go to for lumber *always*
measure after cutting to make sure you're getting what you asked for.

Yeh, I just use it to reduce in size for fitting in the car. I always
ask for it oversize and trim at home, since I'd not trust them to get
it right. Shame really - those vertical panel saws they have are
amazing.

They're the reason I buy my sheet materials there, saves me ages on
getting nice clean cuts. I am always clear that I want dims x, y & z
_finished_ size and rarely have problems once I make it clear that is
what I want. I've only had to say, "hold on, I'll get another sheet and
you can try it again" once ;-).

I always check them as they come off the saw.

Our local B&Q don't offer a cutting service - any clues to those that
do? (eg "warehouse and above", or " the ones North of Watford" or
whatever). The 'local' proper DIY shop with a panel saw shut a year or
two ago, unfortunately.

Thanks

And if you get a trade card, you get free cutting and the sheets are at
a more reasonable price too.

It's virtually free cuts for everyone now, used to be 5 free cuts per
sheet but it's jumped to <a much bigger number[1]> 'per visit'.

What's the ballpark discount for sheets on a trade card?

[1] I want to say 10 but I'm sure it was more, no, 25 is too high, let's
say 15.

Yup, 15 cuts at ours. That said, I have on occasion had more than that
done for free - helped partially I am sure by going in armed with a
neat clear diagram of what I need rather giving ambiguous verbal
orders like I've seen many do. An excellent service in my view, and a
significant reason for me to keep going back.

I'm bemused. I've never had sheet materials cut to size. Buy the panels,
take them home, cut to size using circular saw or hand saw.

That way I can buy them for a fraction of B&Q rip-off prices.

I do not have facilities to transport full size sheets. I do however
have a very professional wood yard not too far away.

If you can transport an 8 x 4 sheet...

At least one of our builders merchants has a panel saw so you can buy
there and still get it cut.

Yep - you do have to check with a tape measure before leaving and always hand them a piece of paper with the measurements, make them write it down and keep an eye on their piece of paper as well as pocketing yours! A staff member will always lend you a tape measure. I've had the above experience more than once and am now extra cautious! If you require very accurate measurements and you're calculating out how many lengths you can get from a sheet, it's worth remembering the saw itself takes a few mm off each cut. I can't remember how many???
