1/12 scale Alfa Romeo 8c 2300 roadster build log [COMPLETED BUILD]

some more work done

The kit's leaf spring mounting brackets are split in 2 (probably for ease of moulding). I modified them so that they are now 1 piece which permits me to incorporate a small hex head bolt as a grease point.20230102_161820.jpgAlfa-Romeo-8C-2300-Monza-1932-asta-35-768x576 crop.jpg

All 4 spring sets are done and painted20230103_221541.jpg

Predrilled the frame and body parts for the lockwire bolts20230103_123038.jpg

Modified the fenders to look a bit more like the ref car (still needs some sanding)

Well ok, the fender thing isn't really working. The real fender has a stamped aluminium rivet plate (last photo in previous post) , that's what I was trying to do with the white plastic but I didn't like it so It was back to the drawing board. I decided to make my own stamped alum rivet plate, just like on the ref car but 12 times smaller.
I first made a stamping die20230104_101044.jpg
I then roll formed a .005in alum sheet 20230104_101126.jpg20230104_115713.jpg
and voila, 8 stamped alum rivet plates20230104_120542.jpg20230104_100936 (1).jpg
The lock wire will be installed once the paint is done.

I aslo did the seat back in red leather, still needs some fitting but it should look good20230104_143911.jpg
 
Started a new build today. As stated somewhere in another post, I was awaiting for my birthday gift which I got last saturday. It's an Italeri 1/12 scale Alfa Romeo. A very nice kit that, from the get go, is pretty well detailled. I could build it straight out of the box and it would look real fine. But me being me, that's not what I want to do. I'll try to super detail it till the sun don't shine. Once again, the operative word being 'try'. Here are some mods that I would like to do.
1- replace plastic spokes with metal spokes
2- replace plastic leaf springs with brass
3- upholster seat in leather
4- add missing nuts and bolts
5- create a fuel tank (the kit doesn't have one)
6- super detail engine by replacing certain plastic parts with metal ones and adding as much details as possible
7- ....

So I decide to start with what will probably be the toughest part of the build, the respoking of the wheels.

My first impression of the taskView attachment 344163
After a few minutes of pondering, I set out to make a jig that will locale and index the different parts of the wheel (the hub and the rims) once the plastic spokes are cut off. I will then have to drill 80 0.5mm dia holes per wheel while respecting a determined pattern and insert 40 metal spokes while respecting the lacing pattern. There are 5 wheels. Yeah, right...View attachment 344164View attachment 344165

More to come...
Very well done model,
The Alfa 8C-2300 Monza is the car I would purchase if I ever win the Lotto. I have several close up photos 8C 2300 that show parts of the suspension, wheels, Interior and the timing advance on the car. I also have some photos of the factory drawings for the car. if you send me your email address via the forums message system I would be happy to send them to you.

Thank you Jim. I totally agree with you. I restored a Triumph TR6 back in 2006 and said at the time, "never again". But I definitely would restore an 8c 2300. I sent you my email.
 
Finished the seat today, very pleased with the result.

The kit seat


François

The seat is stunning.
What did you use to cover the seat, bookbinding Leather?
 
Thanks
An old pair of leather gloves my wife didn't une anymore. For the piping I used a 0.05in dia styrene rod that I color matcher.

Did a bit more work today.

1- The seat on my ref car has a divider in the middle and, since it's a race car, it also has racing belts. So I made the divider but I'm not sure if I'll but it on yet. As for the belts, I'll see if I want them or not later on.

2- I also decided to redo the floor pan. The kit's pan is a not so good with wierd checker texture of some sort. The idea is to replace the front portion of the pan along with the 2 side stiffening rails which will be made as 2 separarte parts. I'll keep the plastic rear portion where the seat sits.

I'm still at it!! Doing a lot of prep work before priming. The kit uses a lot of slotted head screws that I really don't like. They are manly used to assemble the different suspension components, both to the front and rear axels and to the frame. The real car did not use slotted screws for this. It was mostly threaded studs sticking out of the frame or hex head bolts and nuts. I'm replacing these screw either with brass studs that are threaded into the frame or with hex head bolts. I aslo added grease points on the leaf spring pivot bracket and replaced many small plastic blobs that are supposed to represent bolts by nicer 3d printed bolt heads and nuts. Here are a few pics.

Still a lot more do do and still having lots of fun doing it!!

Great detailing, François. Loved to see your pictures.

I noticed one of your reference photos showed seat belts. A race car from the '30s would definitely NOT have seat belts. Of course, a restored one driving around today would have them installed just to keep the valuable windscreen protected if you rear-ended someone...

I'm also dubious of all of the bolt safety-wiring of your reference as well as the dead-flat ("frozen") paint finish, but it's your choice.
