Bob,
As others have said, you can nail wood onto the joists to bring your
spacing back to 16" centers, but there is another problem that needs to
be dealt with. 1/4" plywood will sag when nailed on 16" centers\ over
time, leaving you with a wavy ceiling.
I would consider:
- Nail 1x4's on 12" centers across the joists and block the joints where
the bead board seams land.
- Cover the ceiling with 1/2" plywood and glue/nail the bead board to
the plywood.
- If the existing drywall is not sagging, strip off as much paint as
possible and nail/glue the bead board to it.
These are in no particular order.
Let us know what you decide on.
Peace,
Pat
