Stupid question time. Why didn't you make the wing in one whole panel? - ie from your join on the rear lamp housing and one long seam where you are welding at the top? It would seem (to me - never having done it) that it would be easier to it that way? No not a stupid question. You are quite right and someone with more skill would have done it that way. But as truckdoctor rightly points out smaller pieces are easier to handle without the risk of losing control of the shape. I'll definitely try it as one panel on the other side. Following on from the above, I've just realised that in this case, the panels do have to be two separate ones because of the wheel arch which if I'd tried to make it in one would have caused a lot of trouble. It might have been best to have had the vertical join in the centre of the arch but I stopped where I did to line up with the piece above. |

Just catching up on this. Great work, as so many have already said.
What are you going to use for a rear window? Do you have a donor in mind?

I made the aperture for the front screen to accept a Fiesta screen but on the rear I cut it out of a Fiesta tailgate so a standard Fiesta window will fit. The rubber seal will allow the aluminium bodywork to slide under its lip which will hide the steel to aluminium interface and should be quite neat. |

This panel has given me a lot of grief all down the line, the biggest problem being unwanted bulbous shape in the centre where very little shape is needed. Even with the lightest of wheel pressure for smoothing it was difficult to avoid raising the area. I've read about heat shrinking but never tried it so this was a good opportunity to give it a try and it worked very well. These photos show the "Egg" that I needed to lose.   And these after shrinking.   I think it has turned out as well as I could expect and I could do no better which is always my yardstick. If I've done my best I cannot beat myself up for not doing a better job even though other people could achieve a higher standard. |

Well today has gone well more by luck than anything else and the adjoining panel is now formed and ready to weld together.  The section going into the quarter light aperture will be formed separately because it may have to be welded to the main panels when the aluminium body is in place. I'm not sure but am keeping the options open. |

Well, yet another day when all has gone very well and the rear three quarter panel is very nearly there with just a bit of planishing needed on the front piece to tidy it up. Here is how I prepared the panels for welding and welded them together. If this is boring or too basic please let me know. When two panels have to be welded together they are overlapped and a scribe used to mark the cutting line and one or two transverse lines to ensure that when the two pieces are clamped together for welding they line up perfectly.  The piece underneath is trimmed and filed carefully onto the line so that ideally there are no gaps when the two panels are brought together. Each piece is wire brushed to remove any oxide and wiped over with acetone. Once clamped tacks are put in every inch or so which have two purposes. One to hold the two bits together and the second as bridges to transfer heat from one to the other.   A bit of sinking occurs either side of the welds which is rectified using a hammer and dolly. The panel was then fully welded.  The penetration was quite good but using no filler a fusion weld was carried out on the underside.   More planishing to raise the welded area and a body file used to take off the high spots.   |

I've just found Lazze's video which shows how to make the clamping jig that I call the Octopus. I just thought this might be helpful for anyone who wants to build one. I'm finding it enormously helpful for holding odd shaped panels while leaving two hands free for planishing.

wow, this is really superb, but I keep thinking you could have built someone a ferrari special by now and make yourself a few hundred thousand

Intrigued if your wizard friend can sort out the extra bow. When I was making the infill panel for the Jag sunroof I put too much of a curve into the first one I made and couldn't for the life of me get it out. Although I didn't have a wizard friend to point me in the right direction  |

Intrigued if your wizard friend can sort out the extra bow. When I was making the infill panel for the Jag sunroof I put too much of a curve into the first one I made and couldn't for the life of me get it out. Although I didn't have a wizard friend to point me in the right direction The problem is that four years ago when I wheeled up the panels for the lightweight I became quite reasonable at it but over time I've forgotten the little dodges that get you out of trouble. Trev reminded me and Wray Shelin's great video backs him up that it's an easy fix. Just place the panel on its side on a low bench and with you body put some bend in. Wray calls it a belly fold or something like that. The transverse curve can be checked by holding the panel on the buck and pressing down. This shows if there is too much or too little shape. If it needs more shape more wheeling is needed which will put more bow in but that removed by the belly fold. If there is too much shape the edges of the panel can be stretched by wheeling to remove some of the CROWN. So there's the theory. I've just got to do it now PS He also covered how to remove any wavy edges from the panel which I have never known how to tackle. |

Wow- what a fantastic thread!!! I have not been on RR for while and have somehow missed this. These are the sort of builds and write ups I love the most. Hard to stop reading until finished. My wife Hannah is now enjoying reading it through. Its of particular interest to us both because my dream build for the future is to build my own car styled as a LMP type race car, but not as ridiculously wide. It will be started with a Lancia Stratos screen and built out from there and a mix of steel frame with alloy cladding. Hence your thread is gold for us! Question time. I'd be tig welding too and wondered if you can anneal the welds afterwards to make the shaping/filing and smoothing easier without cracking? Link time- there is this outfit in NZ that build stunning replicas from the confines of an old chicken farm. All way above my pay grade .... www.rodtempero.com/Thanks so much for the time you are taking to share your project with us. Alex |

Oh also- I admire your sensible thinking when you decide enough is enough and to move on rather then strive for perfection because it can be very easy to get carried away and muck it all up............

Say hello to Hannah please, no I'll do it myself. Hello Hannah. now I know you are reading my drivel I promise to keep to the subject and avoid any blokey humour, honestly I don't know if you have come across this YouTube channel but the car they are building reminds me of an LMP. I like their banter and the work they're doing. I had hoped to report that after a couple of tweeks my roof panel fitted perfectly, but sadly it isn't the case and it is becoming a war of attrition. I didn't spend long on it yesterday but by the time I packed up it didn't fit any better than it did when I started so not the best of days. I may have to enlist the help of my long suffering wife to do a bit of wheeling but I'll persevere today on my own and then see where we are. Re annealing the welds I haven't tried it but it should work I would have thought. Many thanks for the link to Rod Tempero. I have come across him on one of the Facebook groups. He produces really stunning work. |
