Treating "Nail Sickness"
Hi, I'm currently in the process of restoring a 45 year old clinker (Lapstrake) Folkboat which has been out of the water for some years.
Whilst the lands of the planking have remained surprisingly tight, nail sickness is showing itself in the paling and softening of the mahogany.
Fixings are copper nails and bronze screws at the transom, stem and all the floors. It is actually the screws which are most affected and I can't remove them because the heads disintegrate and screw removers are ineffective.
The long shot of it is basically can I get round the problem without removing them and any ideas about treatment?
