Stephen Nuding writing for Fine Homebuilding prefers a butt joint for
joining pieces on a wall longer than the stock. He says it looks better
IF the pieces shrink, as opposed to a scarf joint. Can someone explain
why a glued scarf joint wouldn't stay together better? I just installed
baseboard today, and as usual, made scarf joints using nails and glue.
Seems to work fine on baseboard. So is there something a bit different
about crown that the joint would look better as a butt joint?
