Ed, Swifty, Gary, Mac & Scottie - Thanks for all the replies gentlemen.
House Windows - I think I will wait until I have finished the build before sorting them out.
Unfortunately, the ones with the most damage were only fitted in 2009 when the garage was converted.
Welding - I must confess it is good to be making something for a change, rather that butchering fibreglass.
Bonnet Bulge - Just to be clear, I am only looking to flatten the bulge at the back of the bonnet so it matches the scuttle profile.
This only needs to happen at the rear of the bonnet and the main shape between the wheel arches will remain.
I took this photo this morning, it is not great, but you should get the idea.
The Spitfire bulkhead is original height, so everything in the engine bay sits lower than that.

If you build it, hinging will come...
I had two thoughts about
Mister Towed's scissor hinge design...
The first was that this was his second attempt at making some bonnet hinges that would work.
( And similarly
Mac needed more than one attempt to build his hinges too. )
The second was how to make space for the scissor hinge below the chassis line so the section of bonnet below the grille opening wouldn't foul them.
I thought that simply cutting slits out would look terrible, but an "upside down" bonnet bulge would work.
At this stage I don't know if I will need anything, but at least I know that it shouldn't be a problem if I do.
This still might look at bit odd, but then again, quite a bit of my build will not survive close inspection.
Anyway, all this means that I have stopped trying to work out a perfect hinge arrangement in advance.
Instead, I will simply build a MkI version and see how I get on, then adjust and build a MkII version if necessary.
This approach is a big help, as I can't really sort out the bonnet, until I have working hinges.
As the hinges will determine the angle at which the bonnet will meet the lip on the body shell.
So once that is established, I can then adjust everything else to line up properly (
touch wood).
I found the cardboard template for the grille and gave it a light trim for a slightly better fit.
This made it easier for me to mark up a centre line between the two factory fitted hinges.
I also taped some parking cardboard to the radiator cap, to ensure I maintained enough clearance.
It was a bit of a challenge to get the main section of the bonnet into the right position.
But that roughly lines up the bonnet with the centre point of the chassis.
This will be my MkI hinge design.
So I trimmed a bit off the "L" shape I made yesterday.
I am going to use the two thin off cuts as locating "lugs" (more on that later).
I then cut a matching set of pieces for the other hinge.
Next I had to use some spare lengths of the flat bar to allow me to clamp the lugs into position.
Once welded and tidied up they now look like this.
I plan to simply bolt the "L" plate to the factory brackets, which will sit inside these lugs.
After welding the other pieces together, I now had the two "bonnet sides" of the scissor hinge.
The "chassis side" of the hinges will be a simple length of flat bar.
However, I may need to cut them at a slight angle before attaching them to the chassis.
The only other thing I managed to do today was to get some normal body filler on the scuttle.
Before I packed up for the night I gave that an initial sanding down along the top edge.
I plan to re-draw a line for the vertical face, slightly closer than the guide line I used for the fibreglass filler.
This should hopefully give me a nice straight face.
Until next time, take care, Paul.
