Dovetail


I made some handcut lapped dovetails to attach some drawer fronts. White
Oak fronts onto Ash sides. They have broad tails - 2 per side. The
results are OK however two of the drawer fronts had cupped and I had to
use clamps to bring them together on glue-up. Now I am wondering
whether in the future, stresses might force the joint apart. I
thought about drilling 2.5mm pilot holes into the corner of each tail
and then hammering in a nail with the head cutoff. I will then punch
the nails below the surface & then fill the holes with a bit of
filler. Now I know it ruins a bit of the appeal of the dovetail and
should be unnecessary for a properly made joint however I reckon it
must make a very strong and stable joint.
Anyone think this is a good idea?

Orienting the grain right helps. Easy to remember

Did a 7 drawer unit for under the drill press - drawers half
blind dovetailed together - front and back. No glue at all
and they've worked fine since late 2002. So far so good.

I suspect that the parts weren't flat to begin with

If you are considering putting the nail in the side of the drawer I would
not bother. If the glue won't hold it the headless nail certainly will not.
Now if you put the nail in through the joints like a hinge pin you might add
strength. If your joints are tight fitting the glue should be enough.
