Fiat 806: research and scratchbuilds


Recommended Posts

not ready yet, but I promised to show my floor...

Without the tanks and unfinished foot board...

806-007_zpsuvb85h0w.jpg

Looks terrible without the tanks, but it shows the cradle I made for them.

I shortened the floor, because I think it serves no purpose behind the seat. Will make the frame tube/rod there from aluminium or brass tube.

I'll also make a support frame for the fuel tank (something like that is visible on drawing 2)

To do before painting: Make the holes in the footboard, rivets and bolts, tidy the hole in the floor and seat attachment beams.

 

More soon,

Dear Robin , this looks very convincing ! Regarding the support frames : This frame seems to be connected with another one right before the tank.As we know and also can see

  ( photo 2 for

instance ) there was also  a support frame at the beginning of the bodywork. ( U-shaped imho ). Maybe this other rear  frame was extended and connected with the rear bodywork so the rivets would make sense we can see on the rear of the car ( photo 3 ) Another frame was situated before the steering wheel to hold the steering column imho .

Many greetings !  Hannes

Sorry guys, I had no time to read your posts. I will this week-end. Waiting for that, a little topic about my stands for leaf springs. I had just cemented my 2mm alu tubes (see above) but it was too fragile. So, I have used another method, first drilling a hole (0,9 mm)...

... then introducing 1 mm brass tubes in that hole (lenght 15 mm). After check, the tube is cemented in the hole:

... and then cementing my 2 mm alu tube on the 1 mm brass tube. This is the base for my stand scratch construction:

Olivier - looks like it is really starting to come together.

 

Hannes - That looks like a very convincing way to represent the slots if that's what they are. It's a still a bit of a puzzle to me. Just looking at photo 2 again. At the front the tabs look like they have been cut as part of the same sheet as the triangular lower fairing and then folded. A bit like the top of the walls of a castle that are then folded out. Why would they do that? To me it almost looks like they hold fasteners - there is a shadow on the front tabs. Maybe they are just used to screw the panel on. I guess they could not rivet it because they needed access. Same with welding. Would have been a pain to remove though! If this is the case it does not look to me that the slots are the full width of the frame so would not have been much use for drainage.

 

What do you reckon?

Dear Nick , you are right , that´s confusing . We don´t even know  if a bottom panel of the size like shown in the kit´s solution existed or not.  A great panel  also means more weight.If there was a pinnacle -like folding of the sheet around tabs  the alu could rip apart at these places imho .

The best I can do to solve this problem : I´m going to visit Mr. Laube again next week  , a specialist regarding alu bodywork for vintage racing cars in my hometown and ask him for his opinion about  this construction. Maybe he can help us ! Photo 9 in hi-res shows these parts as a cramp-like construction. Look at our chat-sides !

Many greetings !  Hannes

It doesn't bother me at all, but I'm afraid it will start to bother you at some point.

Dear Robin,

you are right! I have decided finally to remove any trace of wood. It was not a good idea to keep that, but I think I just needed to grieve my floor :(!  (and I don't say that for you to feel guilty! ;))

Dear Olivier how to represent the bottom sheet ?  It´s not easy but I thought about a solution with the thinnest  brass sheet you can buy ( about 0.1 mm ) On this sheet small strips will be glued and this construction must get cut out exactly according the frame´s profile . (make a pattern first with cardboard or similar )

The main difficulty is the fact that the openings in front of this sheet are situated too high too !

My solution : I will add plates  on the downside of these openings so they are on the same level as the rest of the bottom panel .

The panel must get painted first before glued to the downside of the car so the openings cannot get filled with paint .The rear end of the bottom sheet will be where this cramp construction is situated ( part 3 A ) so the transition will be invisible .

Many greetings !  Hannes

Dear Hannes,

your solution to represent these slots, that are indeed probably for water drainage, is very clever and impressive. I did not think going so far myself, and you are definitely the first to imagine such a construction. There, we are million miles away from the original kit. Will I follow you on such a construction, will I make a compromise or even not represent at all these slots, I don't know yet. My bottom panel was supposed to be over.... But I admit your solution is very tempting...

In order the reader understands well your idea, Hannes, I have thought it would be useful to show the strips you want to reproduce. They are so thin that you can't see them on photo 28, which is a LD photo (I hope we will get one day an HD one...). I don't know where you saw this construction begins from the part 3A, but it is indeed very probable and logic if it is for water evacuation, as we can think. In my case, I would have to cut the front part of 1G (bottom panel) one more time, to introduce the strips between the frame and this part. A lot of work...

Your suggestion to use 0,1 mm brass foil is certainly very good, I am gonna order it.

To make the strips between the spaces, I would suggest the ref. 123 (0,2 x 0,6) from Evergreen.

When I will go to the Centro Storico at Torino, I will try to make a photo of the Mef's underside (I hope they will allow me to do that!). Of course, both cars are different, but it will give an idea, and will be useful anyway for my Mef build later...

Dear Olivier , the Mef had closed body panels from the beginning imho so unfortunately this won´t help us regarding or research  . I was studying pics of the Mef for months and _ as Sam said _ there are not much correspondences . Btw : I found a new photo of the Mef with a stream-line bodywork . If you are interested in that photo , look at my link in Sam´s thread !

Many greetings !  Hannes

Dear Hannes,

Ok for the Mef. I will definitely return and see Sam excellent thread when I will build the Mef. For now, the few free time I have for model making does not allow me to do anything else than focusing on the 806.

All the best

Olivier

Dear Olivier , I found this photo when searching for more informations regarding our 806 .There´s always the possibility you can find out more if you search in  the Alberto Massimino , Carlo Salamano or other sides. Pity, they already died in 1975 and 1969 because especially Massimino could have answered a lot of our questions.Maybe Massimino  wrote private remarks regarding our car which never were published for legality reasons. Rogliatti wrote  in his article , that Massimino handed him over all his notes . What happened to them ?  Hannes

I don´t know if you already noticed : On drawing 2 no seat fairing exists anymore and the seat cushion for the driver´s back ends with the bodywork..

And regarding the frame : In my opinion the center part is the same but it was altered and shortened at both ends of the rails . If I had known that before , a lot of alterings which I have to do now could have been avoided . But I guess ,thats a necessary part of the learning process.

Many greetings !  Hannes

1) Now, no more trace of wood on my floor.

2) I am working on my rear leaf spring stands: maybe I will have to step back of 2 mm my front stand on the frame, in order it to fall exactly on the front part of the leaf spring.

3) To make the stand, I first get 2 holes spaced of 6 mm with a 1,5 mm die, ten I cut a rectangle and I get small and small the goos shape for my part:

I did some research regarding the protection screen of the steering wheel . Salamano said in his 1960 interview , this screen was made out of Plexi-glass.

That´s impossible , because .Plexi-glass was invented at the end of the 20´s and the patent was given 1933 . !928  safety -glass with several layers of glass was produced for the first time .

I wonder why Salamano  made wrong remarks about a car he was driving personally and with this screen right before his nose !

Maybe the Fiat engineers developed a predecessor of safety glass or this screen was made out of fine metal-mesh according other sources .

Many greetings !  Hannes

Today I wanted to show you some pics of my altered bodywork. The fairing was made flatter and now a Bordino tip is estalished .  After some alterings on my radiator case I will post some pics of the car on the cradle.Alterings of the frame are necessary too :

Many greetings !  Hannes
