Ex-Racer Spitfire Mk1 Rebuild


Recommended Posts

I often check out race cars for sale ( I know just torturing myself) but ever hopeful that someone doesn’t know what they are selling ( disgruntled ex-wife) and pick up a genuine cobra or gt40 for £20k !!!

but I did think this spitfire was a nice one and made me think of this thread. Spare engine and everything. 
drivers seat is on the wrong side tho.

So I dragged the old blue bonnet back in. 1, 2, 3 ... bonnet overload..

Having one off the car seems to take up most of the garage. Three must be loads of fun

^^ This!

 

That German Spitfire does look nice.  Seems like big bucks, but actually you probably couldn't build it for that.

How plans evolve. Apparently I seemed to think that this next bit would be quite quick. Meh..

The vertical panels above the 'D' sections took quite a bit of fettling to get them both deep enough and level enough to take the transfer moulds off them. Even then I gave up with the curved section at the front to add on later. I did add a bit of correx to make the flange that exists on the metal panel though but didn't bother at this stage with the return on the bottom (top with the bonnet the right way up) that provides rigidity. Trying to hand layup glassfibre upside down is a non-starter. Lots of filler needed along with some primer to seal that.

Made the transfer moulds which were trimmed and more correx added primarily to form the basic shape of the curved section at the front and the stiffening flange, plus an extension forward to mate up with the side of the grille surround.

I was rather pleased with myself over how these turned out. Only thing I did forget to do was to form a large radius wax fillet for the return. So had to bodge it a bit by building this area up with enough gelcoat that I can then sand back down later when I made the patterns from these moulds.

As I said about plans evolvng. I had intended fitting the two final pattern parts of each side together and then take a single mould off that for making the a one piece left and right part. The register being along the added flange. However once I thought about it some more I realised that it would actually be a lot easier to make and get everything to line up on the bonnet and inner arches if I kept them as four bits that get can glued in separately. Main impact there is that the 'D' panels need an extra flange along the curved edge to fix the the return on the bonnet itself.

So after rubbing down the first one was stuck to a bit of glass (using Blutack) and a wax fillet added all round remembering to make it a nice big radius.

And then the GRP layup to make the patterns off these. My head hurts thinking of which way round everything is, negative vs positive. Especially as the 'D' panels need a male mould whereas the vertical panels need a female mould.

Only one bit of glass so the second 'D' panel still to be done. The reason for making the surround so wide should become apparent when I make come to make the moulds themselves off these. I hope. But you know about plans and all that.

That will have to wait for a bit though as I am off to Mallorca for a week with my bike :cool:

What? What is this “wait”? :o

I like Mallorca….. young sir very much likes it for cycling and has been several times. 999km in 8 days on last visit.

Hopefully you are early enough in the year for it not to be ridiculously hot (though had been unseasonably warm in Spain recently). We went as a family in July and it was roasting…… even the locals were moaning about it.

Have a good one :smile:

I don't understand much that is going on, but I understand your head hurting in the context of males and females, negatives and positives.

Enjoy your holiday Colin!
