the hardware store cut the plywood into pieces about 1/8 too short.

I can still use them but not quite as planned.

The steel supplier delivers steel oversize all of the time. I just
learned to have more scrap. Getting less is a problem.

Last time that happened, I had only the guy in the mirror to blame.
Fortunately, I don't have a mirror in my shop so he didn't have to endure
my wrath. :-)

If it's important that a piece not be under a specific size, there's two
ways to handle it: Have the piece cut oversize and recut it yourself, or
tell the guy doing the cutting about the requirement. I usually use the
first method, but have occasionally used the second method.

Sounds like they cut to the wrong side of the marks so you lost the width of
the kerf... or the end of their tape measure was buggered up!

Some years ago, I seem to remember being told up-front at a lumber yard
that, while they'd do a pretty good job of cutting, it wouldn't be with
the precision of a cabinet shop.

If there was no line, they probably used a different measuring tool. No

My guess-- he marked the measurement, then cut on the "keep" side of the
mark instead of the waste side. I usually put an X on the side of the
measurement I want the blade to cut to avoid such brain-farts.

I see hardware store saws as rough cutters for convenience. I would
never use them for final cuts because I would never trust their
accuracy, straightness, or for a clean cut.

When I worked at the Depot, the guys in lumber told customers they could
only be accurate to 1/8". I never understood that. If you can make a mark
at one tick on a tape measure, why can't you make a mark at another tick -
the right one? It's not because the saws were innacurate - they were not.
I used to get called over to make cuts from time to time when lumber needed
help, and I never found the saws to be anything less than accurate. I used
to marvel at the way guys would talk between themselves after a customer
left who had insisted on precise cuts. Just never did get that.

I mark my cuts with a pencil like this:

|- or -|

to show that the blade goes right, or left, respectively, of the line.

Probably a store policy to keep people from bringing stuff back because
the store's tape didn't match theirs. Heck, I can take three different
tapes that I own and they're be an eighth difference between them all.

In any case, I cringe every time I hear the saws at my local HD. They
sound so dull, it makes your teeth hurt. :-) I'm guessing they've
gone through their fair share of metal and never got replaced.

Actually I believe you end up with just shy of 60" for each piece, not
48". ;~) To end up with two, 48" long pieces the sheet would have to
be 96" + the width of your saw blade kerf.

When building base cabinets that are traditionally 24" deep, I minimize
waste (IOW, getting two, correctly grain oriented, end panels for the
cabinet sides out of one 48" width sheet) by cutting the end panels 23
15/16" wide, then cut the dadoes in the FF's to receive the end panels
3/16" deep, instead of 1/4".

That way I end up with an assembled base cabinet that is precisely 24" deep.

Sounds a bit anal, but we often build for spaces that don't yet exist,
so religiously maintaining that type of precision throughout a project
keeps cumulative errors from causing problems during installation.

How thick is the face frame? Assume it's 3/4:

23-15/16 panel
12/16 face frame
3/16 dado

23-15/16 + 12/16 - 3/16 = 23-24/16 or 24-1/4

If the face frame is 1/2, then it works out to 24 exactly.

John

Check the thickness. See if it is a real 3/4" or 1/2".

So much is metric that is close. Trimmed down and that is it.

If you have a local ply mill then the buyers might buy from it.

Depends on where the forest they use is. If in South America then
the ply comes from there. Lower cost to ship.

If from a local forest and mill structure - it might be metric or Imperial.

And cutting a 96" board in half won't give you 48" x 48".

Check the manufactuer's website spec's given earlier...they're in
English units, 48x96 at thicknesses 1/32" under the nominal historical
dimensions.

Nobody's claiming you can take a length and remove a kerf thickness and
have the initial total length and my only comment was that US
manufacturers are still using English nominal measurements for at least
construction ply; some furniture/cabinet-grade products are otherwise.

I could be wrong here but I don't think any "normal" cabinet face frames
are 1/2" thick.
