Developping a new Bagheera Bonnet pannel III

So, let's look to a standard serie II pannel
(2 types of pannels have been used)

This picture is coming from my black X 1979

As you can see pointed in red, there is a gap between the outside skin and the panel.
Only the external profile (all the surrounding) is glued.
Left like this, the strenght will not be there.
The fiberglass panel is too flexible

If we position the mold on a skin and hold the surrounding with grips, we will find the same gap .
I mesured the gap with a micrometer and wrote the size in red on the panel.

As you can see, even a screwdriver will enter that gap :

There is also another issue.
Actually the side of the steel pannel was displaying a small crease.
The goal is to quide the glue.

Now if from this mould I made a new panel. At best the outside of the pannel will display this. But not the inside. µ
That won't be a big issue except that in order to reproduce it the fibers needs to bent and fill a very small kind of wave patern. Not easy at all !
So, I might decide to cancel this crease.

Now, time to modify the original shape.
I know that by doing this I can destroy the mold but I took the risk.

I started to cut the side of the panel with a dremmel and the thinnest disk possible
Let's say that we have a square opening. µ
Then, I'll cut 3 sides so that the middle one can be pressed on the outside skin

Then I'll glue it again in that position.
After that, I cut the remaining side, press it and I can glue all the side with the new extension.

Here on the side also

I'm currently finishing this. On the first internal losange, I already refilled the gap with fiberglass loaded mastic.

New pictures soon
