[Public-List] Stern Tube Bedding

[Gordon Laco]

Hello Hernan…

The threads can be restored with complete integrity by filling the holes with epoxy thickened with appropriate fibre…. once cured, drill out the holes a size smaller then run a thread cutting tap in to rethread.

That is quite a secure means of re-establishing your fastenings.
