The other day I went out and bought several sheets of 3/4" plywood for my
bookcases that I was building. I know that the actual thickness of the
plywood should be 23/32" (or just a little under 3/4"). However, when I got
the plywood home and was cutting and testing my dadoes for the shelves, the
pieces didn't fit quite correctly. I got out my calipers and the plywood
was actually a couple fractions THICKER than 3/4". Has anyone else ran into
this problem? I guess I learned a lesson the hard way to never assume
anything!

Did you measure in several places? I frequently get plywood that is thicker
on one end than on the opposite end.

Made the mistake of buying some oak plywood from Lowes. Stuff was made
in china, 18mm thick. Edges were slightly bevelled. Never seen that
before, either...junk stuff.

Yeah, I checked in alot of different places and on different sheets. I even
went back to HD and ALL the boards were consistently this size.

I bought some meranti ply at my local hardwood supplier that, unfortunately,
was of inconsistent thickness. That will really put a damper on your
dadoing. I've learned since to bring a caliper to do a double-check.

Very common circumstance, no matter where you buy your plywood.

To the point that I carry around a short stile cutoff in the truck as a
gauge, with a "project" dado cut in it, for whenever I need more plywood for
a cabinet project that is already in progress.

Well, then that's good news! All you need to do is make your dado a
little wider.

Meaure and cut test pieces for plywood always! The very nature of the
construction method of ply guarantees that there will not be uniformity in
thicknesses.

As for Home Depot, I have recently decided that I will never, ever, under
any circumstance spend any more money on the absolute crap that they peddle
there as hardwood faced plywood. The last purchase I made there ****ed me
off so bad that it was reloaded on the truck and returned.

Did you buy that plywood for abput $24 a sheet?

Yep, I think you run into this with the cheaper
grades of plywood. I never had any problem before
1976 or so using 3/4 fir plywood. My first
experience with uneven thickness was with 3/4 oak
while making a desk for my son. I measure the
ends of shelves for thickness then dadoed the case
sides for the shelves. Sure enough the ends fit
but the shelves wouldn't fit in the dadoes. One
of the shelves had a huge bump (probably an extra
3/16" and the cut edge showed that a piece of had
been shoved a little too far and overlapped
another piece in the same layer. All of my
experience has been with 5 or 7 ply plywood. A
friend across the street gives me scraps and he
normally uses a 9 ply plywood in 3/4". He has
much less trouble with uneven thicknesses that I do.

Something like that. It was labelled "cabinet grade" and looked fine on the
outside. One cut quickly revealed it was not. I have also noticed a
decline in the quality of birch faced ply which normally is about $40 a
sheet. I am done with this place, although I am sure some will say that I
shouldn't have bothered with them in the first place.

Scott, that's an inexpensive lesson. Widen the dados, and finish the
project, and remember next time to measure ANY material before cutting
another piece into which it will fit.

I like that idea.

I happened to talk to the guy that sold this to shipment to HD
yesterday. It was sold nation wide to them. He told me it was 13 ply
Birch with Poplar core. I bought 10 sheets about a month ago, and yes
its not as nice to work with as other types. But for Garage cabinets I
am not going to complain.

Yep. But tightening them up isn't that hard.
just rip a piece that fits in the dado, glue, and
then cut the dado again.

Did he claim that it was "cabinet grade" as the sign said? If so, he is a
liar. Cabinet grade has a specific meaning and this clearly was not. If it
is HD making this claim, then they are probably just idiots. In any case,
there are much better places to buy plywood.

If you happen to talk to him again, let him know that his product cost HD
the business of one woodworker.

I hate to tell you this Frank, but they are thinking of stocking it for
ever. He never claimed it was cabinet grade, that was HD.

Neat. Which makes me think it would also be a good idea to carry
around a chunk about a foot long, with several cuts, all properly
labeled.
