I'm making some basic boxes out of 4/4 walnut (16"X20"X8") as floating night
tables. I have to join them now. I was considering dovetailing, but I'm
running short on time. So now I'm thinking screws and plugs or biscuits.
I've never used biscuits before. Is it ok to use them on solid wood instead
of plywood? Or would they split the wood when they expand. If ok, what size
biscuit would be recommended. Thx.
There is absolutely no problem doing this. I've done it
dozens...nay...hundreds of times. In fact I often have wondered how
well it would work in plywood<G>.
There are tales of folks gluing up table tops with biscuits and
seeing a ghost-outline of the biscuit but I've never seen it.
If you're going to look at b-joiners, take a look at one that can cut
for the FF biscuits. My neighbor has one and uses it on small face
frames and such where a 10 would be too big. He has a porter-cable and
I assume it was pricey since it requires a second blade for the FF

I remember a thread about that a long time ago. Maybe even a whole year.
The explanation that made the most sense to me was that the biscuit swells
from the glue, and doesn't completely shrink back till about 24 hours
after. If you sand the panel before that, you're sanding swollen wood above
the biscuits. When they finish drying it leaves a biscuit-shaped depression
on one or both faces. All of this dependent on how much the biscuit swells,
how much the wood bends out of shape, the weather, the temperature, and
wierd stuff going on at Edwards Air Force Base.
If you're in a hurry, do you really want to be chasing down and learning a
new tool? Dovetails or biscuits will work fine, but for 'quick and looks
just fine', screws and plugs can get you to the finishing stage more
quickly. And the finishing process, especially with walnut, always seems
to take longer than I have budgeted for it.
Now, if you happen to have a good neighbor with the tools and know how
already, go with the biscuits. But it won't be any stronger than the other
two methods you mentioned, (assuming a biscuited butt joint.)
Of course, if what you want is to buy a new tool, I assume I speak for the
group: "Go ahead! Buy that sucker!" (My yellow one works just fine,
who believes that walnut was made for a good oil & wax finish....
