Brilliant thanks for the reply. Do I drill it out much bigger than the existing holes? I guess the size of the dowel available
Cheers

When you buy dowels, buy a drill bit to match the dowel diameter.
In my experience, the dowels should be a close fit; close enough that they won't fall out if you put them in "dry" (without glue) and shake the neck.
When you glue them in, allow enough time for the glue to set. Do not be tempted to work on them until they are properly set.
