      Hi all, having been asked to load my fotki site up on the gallery for reference, I thought I'd basically redo it on here as a build log, because some people have problems with the fotki site.
      This is the real car at Scott Racing, at the time of Brandon, Suffolk.
      The monocoque has to be rebuilt each year, because the power and vibration loosens the rivets AND the glue!

    Measurements and photos over a couple of days and a book full of sketches and notes to self later, I start the drawings to 1/12th scale.

    All you need to start. The sort of stuff you'd have even to build a simple kit.

    The materials to start with. K&S M8F, step-by-step 1/12th build Metal Centre tubes and sections and the outside thin spare metal from photo-etch frets. This kind of brass is crisp and easy to cut. No need for wax to lubricate the piercing saw blade as it is known as half hard, silicon, leaded, or free cutting brass...CZ120 is the techy nomenclature for half hard. The extrusions are in CZ121.
    These materials are cheap as chips or even free.

    These are the first frames to be made. They fit inside the aluminium monocoque and give it shape and strength. K&S M8F, step-by-step 1/12th build sections soft soldered using a modern solder which allegedly has a little silver in it. It used to come from what i called the Chinese junk shop. Now Poundstores. I use a flux called Superflux and a 65W stick iron. Make sure it's clean and HOT M8F, step-by-step 1/12th build . Be bold and quick.
    Holes are done with a pin chuck. Very manageable. I use a smaller drill then open it up with a series of tapered broaches, available from any good tool suppliers.

    The frames shown in position on the first piece of aluminium. This is cut from one piece of K&S M8F, step-by-step 1/12th build aluminium, almost as it comes from the bag.

    Here, the first side pan is made from printers' litho plate. Free from the local print shop.
    The rivets are pencilled on the underside from the photos and then impressed with a slightly blunt scriber onto an Edding cutting mat.

    This is how I do rivets on flanges and odd bits of brass. This is the folded up steering column bracket, being "rivetted" over a piece of pear, a grainless hard wood.

    Tother side done just like the first. The bottom of the side ponds is joggled into the bottom plate, then glued with Evo-Stik, an impact adhesive.

    Looking great, I'll keep this short so as not to effect the build log but I did want to say thank you for posting it.

    The first wee brass brackets, made from thin brass sheet. They are the front suspension pick-up points.

    Many lightening holes appear in racing cars and they usually have been bellmouthed. This makes them less dangerous and a lot stronger, like putting a swage in a panel.
    I make them by making a dished dip in a piece of hard wood (pear or box) Then turn the end of a piece of ally rod so it's just bigger than the hole diameter and then push onto the holes and wiggle it about a bit into the hardwood dip.

    Daniel, thanks for that. It will take a while to get everything loaded up.

    The finished front frame. This takes suspension and brake/clutch master cylinders, so has to be very accurate.

    The finished tub with front frame installed temporarily. It must be removed for painting.

    Time so far to finished tub...38 hours including research and drawing.

    Brackets can be done two ways. Either make them by hewing them from metal sections or mark them out flat and fold. I prefer the latter because it means much thinner M8F, step-by-step 1/12th build metal can be used, but I still use sections for where I need some thickness as a bearing surface for pivots. These were used on the main back frame.
