There is a old thread about structural repairs, which makes some good points, but I thought I would start another one, as I have a question.

Basically I understand that trying to recreate the laminate, with a scarf joint, like the board lady suggests, is a pretty good effort to recreate the original structure, but it doesn't actually recreate the structure, it's a compromise.
i.e. the bottom layer of glass, joins the existing bottom layer, for perhaps a few mm, before creating another mini layer of glass/pvc/glass. Then the same is repeated for the top layer. I am guessing a lot of the strength comes from the very small overlaps of glass/pvc/glass, rather a glass to glass connection, which is a few mm at the most.

So my question is why not do a step, reomoving as much of pvc, so that more of the existing glass is exposed, providing a greater bond area for glass to glass? even if there is a thin layer of pvc still attached to the glass.

Can this be achieved with a dremel, mini router etc, set to the depth of the pvc?
