I just stumbled across this whilst looking whistfully at the Cerbera forum, I miss mine...

Looks like a fantastic machine you're making there, congratulations. What is the foam you're using for your fibreglass plug? I need to make up some wide arches myself and was looking into options.

it is a close cellulor foam made for plug manufacture most good suppliers keep it.

long time since i posted been busy restoring two wedges plus power steering to a griff etc. etc. but now having a concerted effort on the cerb finally finished the power steering column and the mounting for the power unit and lots of work to the n/s plugs for the new wings also laid up the bonnet with the cooling duct for the rad pics on that to follow but pics should give you a flavour of the work.

A fascinating engineering project for us Cerbie pervs. It would make a brilliant TV show.

Love it John, can't wait for your next installment! It's going to need a very spicy engine to do justice to that gorgeous body you're creating..!

Not even just Cerbie pervs - I have to confess I'm not a massive Cerb fan (for me the Tuscan is, and will always remain, the pinnacle of automotive design, although admittedly I'm biased...), but I stumbled across this thread some time ago (>1yr) and am delighted to see that the project is still making progress.

John, I have the utmost admiration for your skills, and can't wait to see the end result. The bodywork alone is an absolute work of art cloud9 This may be a naive question, but out of interest, how do you match up the offside and the nearside given that the contours appear to be hand-sculpted? Do you take measurements at datum points on either side, or is it just a case of judging everything by eye (I suspect not, but would love to know how it's done!?)?

I echo Rob's comments above!!

Well done John....Down here on the S.Coast, we've got some very competent 'hands-on' TVR owners - - But nothing like John!

rob it starts off being done by eye to get a basic shape certainly when on the first stage building up the foam prior to filling and fairing, then we scribe vertical lines at precise distances along the (in this case wing) using a laser level nowadays used to use a plumb bob and use the shadow cast by a lamp, then make a template of that section and form the opposite wing to that shape at that station not easy but with practise not so bad.we will be performing this very soon so will take loads of pics and post on here.

Hello, please excuse my ignorance
To me it looks like you are using car body filler on top of the foam and then you rub both sides down to the perfect shape as you have explained above, I am absolutely clueless as to what happens next.....Do you later make a mould from what you have shaped and then use that mould to make fibreglass panels or whatever, then later rip all your hard work off the vehicle to replace it with those panels
Not that I will ever be attempting this type of work but I am intrigued to know
