Removal resistance. The dowel does just fine in shear, but pullout is
about nil.

That depends on grain orientation -- if it isn't cross grain, there's a
pretty good area for glue joint which isn't 'nil'. Although I've never
done a calibrated test, in end grain which where the dowel would have the
most long-long grain, the screw might not have any more holding power, if
as much, knowing that they'll tend to pull out of end grain...

Would be an interesting test just out of curiousity...


It's been done. See Hoadly on differential wood movement along the grain of
the dowel and the wood which encloses it. Unless you've got the perfect
grain match, it'll work loose from the glue as time passes, the wood cycles
and the glue becomes more brittle.
