Might have gone overboard on the glass a little bit. This is a pic showing the thickness of all the glass now in my finished transom. The wood in my transom from the factory stopped short of the bottom so I also followed that anti-rot feature.
This meant that every layer of glass added came together at the centre bottom where a bung hole would be in most boats, this is a piece from the drilling of that plug (bung) hole. I dont think my new transom will be falling apart any time soon!
