Ahh makes sense, though maybe consider marine plywood for bits of the floor which contact the ground often.
Seen a few LMP cars using that instead of carbon as it's more resistant to wear and cheap when you need to replace it.

Manta project here might get resurrected finally, new job beacons here and this time no more fixed term contracts.

I'll get a thread going once I've gotten it into a friends workshop and given it a good beating with the MIG.

There is an "engineered" hardwood ply, that uses an epoxy binder, so is pretty waterproof, used for boat flooring, but i can't for the life of me remember the trade name of it at the moment! It's heavy, but get you car under the weight limit, and use a "heavy" floor to bring the CofG down, a-la F1 with their brass sumps etc ;-)

I think you mean jabrock, also machines nicely for bits but it is quite expensive

I'll use the lightest thing I can as there's no minimum weight restriction and any weight added above ground raises the CoG. But I'll use some wooden skids for the corners of the splitter. Can't remember what car I saw that on, but it was a nice idea. smile

So lots of sanding today.. first off sanding the filler..



Then added the first coat of pattern coat..



Then spent about 6,000 years sanding that down. laugh

How heavy is it and are you using it to make a mold for a lightweight fibreglass version or is that the finished item - I may have lost the plot here

This is just the pattern, I'll take a mould off it and use that to make a carbon / kevlar part. smile

Thanks - obviously I had lost the plot - hoping you cover that process in as much detail as the rest of the thread

Here's a brief update of where things are at the mo..

Since the bumper will be made separately to the bumper and wings, I made some return edges on the underside of the bonnet so that there is a bonding surface between the two; it'll also help with mould & part making.





Then started to fill the bonnet / wing panel gaps, and skimming the lamp blanks.



This evening I sanded the 2nd coat of filler on the bonnet & wings..





..And also wet-sanded the 3rd coat of pattern coat.



With any luck the next coat will be the last, and it'll be ready for gloss coat then fine sanding!

Is the whole bonnet/wing/light assembly going to be one single clammshell? Or is it just tacked together like that for the sake of practicality? Probably a silly question but...

Yeah bonnet, wings and grille will be a one-piece part, then bumper / valence will be bonded to it.

Edit - Should probably mention the clam will also be carbon fibre.. what's on the car is just the pattern to take a mould from.

Does you "Track" fit inside the std wheel arches, or have they been widened a bit??


(In 2014, a std 205 track is pretty narrow, despite your low CofG)

Ooooohhh no! laugh

The track is widened by a fair bit at 1.5m, so doesn't fit in the standard arches at all! Once I've got the sheet metal in I'll be rolling some wheel tubs and arch extensions.

The front end is now filled & smoothed and had a coat of high-build over the filler. I'll block that all out once the paint has hardened properly. I fitted the bumper to check how much the panel gap will need filling, so there is still a bit of work to do there.





So turned my attention to the back.. I won't have a filler neck and didn't want to keep the original hole, but blanking it entirely would look rubbish, so have decided to copy the LH side so that there is a recess for symmetrical vinyl badges.



Then put the roof on and welded it in place, then fitted the 1/4 panels.









And finally, squared everything up and welded the boot lid on.

Will you be taking the car to the Nurburgring at some stage?

I'm hoping to get it to the DN11 track day next year, but that depends on whether I get it built and suitably shaken down in time.

If the track is wider, why are you making a one piece front end without wide arches, are you going for some bolt on ones?
