As long as epoxy resin doesn't run into supply issues , I'll be there. Thanks Stefan.

I made the mould for the front end today, and sat the thing outside in the sun.
This is ride height.

It came with those shoes. You didn't know I had been at Stretton did you? I heard what you said about me :)

Is it just the photograph that makes it look long? Add the tail and what will be the overall length when finished?

It should have a long tail, more than I'm initially planning. Right now it's at 8 feet which was the initial guideline way back when. To be  more in keeping with the  look it needs to be a foot longer. Right now the extension is a lower priority!

Well, what a last few days. I painted the Jelutong radiator surround with 2K paint, carefully waxed etc and laid up the mould.  I did work in the fibreglass industry so I don't usually have issues, BUT the polyester interacted with the 2 K. I've never had crocodile like this no matter how badly catalysed resin has been. A huge amount of  work that I didn't need. Now I'll just have to wait and see how the first (and only I hope) shell from the mould comes out.
On a positive note I have the bonnet top ready for the final 200 gm/m2 glass cloth. The "hump" is now shaped, and one layer of cloth done. Inside it has pieces of biaxial cloth to stiffen the 1.6 mm ply wood. When the next delivery from East Coast Fibreglass arrives I'll be doing that. Then the tail, and I'm not looking forward to this. The mechanical bits won't fit, so there are some compromises I'm not entirely happy with. So be it.

Crocodile, or alligator is a wrinkling of the item being either made into a mould, or later on taken from the mould. It's usually created when the  gelcoat is not properly cured before laminating. That can be avoided by;
1 mixing catalyst and gelcoat very well, usually a higher rate of catalyst in gel ,compared to laminating
2 Leaving the gelled surface to cure well (ie don't rush leave longer)
3 Make sure the gelcoat is cured, nothing on your finger tip, white gelcoat try writing with a ballpoint pen

In this case rule 2 above wasn't totally done BUT the gelcoat reacted with the 2K paint I used. I suspect both factors are involved. Plan ahead!

Sounds simple enough to avoid now that I know how to :)

After over 20 years in the industry if I can make basic errors, I am sure you might find some too :) In the case of the 2K interaction I found something I hadn't come across before.
 I'll find a decent link for you Marek. IMHO there is a lot of rubbish stuff promulgated on Youtube on 'glassing, and a reasonable amount of good advice too. Despite being an Australian :) this guy makes sense.

There has actually been some progress, despite my having lost some of the will.
As I have said before, compromises are needed, t's a stupid build being so confined in the rear. As a result, and also due to not ever likely to be used in the manner of a cyclekart which I espouse the drive is going back to a centrifugal clutch (horses for courses). I'm using 219 chain to get the sprocket size down so it will fit more closely in the rear.
The final moulding for the front has  come out OK, bump on the cowl nearly ready, bonnet fitted.
I'm waiting for UK customs/UPS/Royal mail to deliver the steering wheel which I used on my Voisin C6 at Tieton to arrive back so I can finalise the steering column mounting. The rear cowl/headrest fairing is a (very) rough shape. Final shaping wil depend on the lump going under it being sorted.
As can be seen  I spent money at the local Barnados, £3 for the two bonnet straps. Useless fact, bonnet straps were compulsory at  Brooklands before the can and fishtail were mandated!

It looks great so far. £3 for 2 bonnet straps sounds like the deal of the century!!!

Charity shops  are good. Wait till you see the Edwardian and "acquired" bits!
Skips and damaged materials from building sites are  good too. Keep those costs under control :)
As a side line I purchased some of the foam insulation board from Wickes (cheap because a damaged corner) hacked to shape for the rear cover and polyester does not stick to it so easy extraction of the shape! No need for foil, or any of the other things folks suggest! It shapes very well too.
