a shelve to fit into, is just a tiny bit larger than expected. I
think the UHMW plastics I used deflected a bit. I should have used

Although it's probably overkill, what I've done in the past is to glue
a thin strip of wood at the bottom edge of the loose shelf and then
plane the strip with a handplane until the shelf fits just right.
This way you effectively make a perfect-fitting shim.

See the post from Upscale regarding Lee Valley's Chair Doctor Glue.
It sounds like it would be perfect for this task. er ah, problem..

How loose? Two thicknesses of 80# paper? That's easily within the
expansion range of any water-base glue, not to mention the hold is at the
end of one board and bottom of dado. Gravity would suggest that you
assemble with the bottom down, so if there is a gap, it's at the
inconsequential upper part of the joint. Cover with tape, solid stock, or
just fill and paint as required the front as required. Won't affect the
overall. If the gap is visible, stuff it with dust before you finish.
Now, someone should have reminded you that modern ply is almost always
undersize. They even sell undersize bits to cater to it.
Next time.

Even there you're in some strange territory, unless you plane your own. At
$8/ft I assume you bought it done somewhere else. Might even have been
sanded, thus undersizing. I think the chair joint stuff is overkill,
personally, but it will probably work fine.
Answer to precision is the router jig, no doubt. I use the guide and plunge
with parallel strips for adjustment like the Router Workshop types, though
doing my own planing helps the fit a lot. On small stuff I'm as likely to
dovetail as dado. Same jig, better hold.

... or glue in a thin strip at the bottom edge of the dado and re-route the dado to the proper
size.

Cut a slot in the end of the shelf board about as deep as the dado.
Then cut a strip the same width as the depth of the slot. The thick
edge of the strip should be "a couple of folded sheets of paper" or so
thicker than the slot you cut and tapered to a little thinner than the
slot at the thin edge (a couple passes with a block plane will
accomplish this tapering). Then when installing the shelf put a little
glue in the slot, set the strip, thin edge first, into the slot -
don't force in in at all, it should set proud of the shelf edge. Then
put the shelf into the dado and whack it in (rubber mallet, etc. not
to mar the wood) this will set the wedge and widen the edge of the
shelf in the dado. This is NOT a good thing to do if the issue is more
than a couple sheets of paper as it could split the shelf board but
sounds like it would work in your described situation and be
invisable.
Of course, the shim at the top as you described seems easier and also
won't be seen.

You might try some of Lee Valley Tools' chair glue. It's designed for
swelling loose tenons of chairs and it dries in the swelled state.

WHERE are you buying your material? That's over twice what I spend on s3s
FAS 8" & wider red oak, even after allowing for the differences in the
value of the US vs CDN dollars. And I live in a classic 'high cost'
area...
Oh, well. The price we pay for the hobby to which we are addicted.

cut a single long shaving with a plane. use that for a shim.
Hi Dave,
First your response to "Need Psychiatric Advice" was absolutely
excellent. I must keep a copy of that post.
As for my problem. "Upscale" suggested I try Glue Doctor available
from LV. On end grain it causes the fibres to swell and then set's
in the swelled position, thus fixing poor joints in chairs etc. And
frankly, I have one wobbly chair kicking around as well, so it might
be a very workable fix.
As for psychiatric advice - I might be being a bit too picky as well.
But I wanted a nice tight joint for the shelves. Even though there
will be a face frame over the actual joints.
I also tried my router jig "a second time". Darn thing was 99.9%
perfect on the second dado. I guess it gets better with age.

Up here - That's what Home Despot calls S4S Red Oak.
It's $44.64 for a eight foot long 1 x 8 board. (3/4 x 7 1/4 x 96)
Then add 15% in taxes. Total $51.34 $9.65 bd ft.
That doesn't include the planing or sanding you have to do afterwards
to actually make it look like S4S board.
Unfortunately in my area, there's only a few places kicking around to
buy wood.
There is one "true" supplier, a mill. The prices aren't much
different than Home Depot, and in their case, Cherry is $15 a bd ft,
and you still have to add 15% to that for the taxes.
Yes, this is an expensive hobby.
Like I wrote previously - this oak ain't getting painted. {Smile}

Paint Red Oak "God Forbid" a 1" x 8" x 96" board cost me $50 CDN
"Upscale" suggested Glue Doctor from LV, which is made to swell the
fibres of the end grain and sets in the swelled position. I think
that's a better alternative to try.
As for the rest. I was using solid stock, not veneer ply. I had
even built an adjustable dado jig for my router, which was made
specifically for the bit and router I'm using. What went wrong and
caused this little problem is beyond me. The second dado, which I
routed at a later point, after double checking the jig and getting
everything clamped in place, was 99.9% perfect.
