Looks like you're off to a good start. Keep us posted.

I am not shy about cutting, adding and subtracting parts to build something unique.

Great math work!
Kind Regards,

I have scratch-built an alternator to replace the poorly-molded one that came with the kit. The parts are drilled and threaded from the rear side for assembly. This series of images shows the washes used on the metal parts to give a corroded and oily finish. This is my first time with washes ...I am using thinned oil paint over Krylon Dull Silver.

A few other images of engine parts...

Could you outline the wash your using, products and how?

[Tage]

Oh jeeze, now we are all gonna have to wash....

[Dougritt]

Here is the technique I am using for the washes ; I am attempting to give a very oily appearance which often is seen on older cars which have not been restored. This technique replicates the corroded grey finish seen on the prototype castings. I have retained the mold sprue marks which are often in sand -cast parts (the embossed circles on the cylinder castings).

1. Prime the plastic surface with Duplicolor filling primer .
2. Sand with #400 grit... sand marks okay.
3. Dust spray with Krylon Matte Silver spray and let dry.
4. Even spray coat of Krylon Matte Silver and let dry.
5. Mix Reeve's Dark Gray Oil Color Paint (artist tube paint)into linseed oil. Try to get an oily look and a consistency of coffee.
6. Using a 3/4" brush, liberally brush all painted surfaces and dab lightly with a lint-free cloth. When you get an appearance you like, stop and let the part dry. The Krylon paint takes on a gray appearance of oxidation with a hint of metallic accent. If you want more metallics, just dust the surface with Krylon until the appearance is correct.
7. Let the parts dry for 24 hours...oil paints take a while to dry.
8. If you prefer a glossier finish, spray with gloss coat. This will also allow more handling without damage.

I have not been able to find a wiring diagram or suitable images to know where tubing and wires attach on the original Alfa Romeo engine and terminate on the chassis. Can anybody help?

Thanks-
Doug

[Dougritt]

The attached images of an original Alfa 8C engine block show the finish I am attempting.

[Dougritt]

Some updated images of the engine systems as they go onto the engine block...

[Dougritt]

The engine block halves are shown here.

[Andym]

Which tubes and wires are you working on Doug? I may have some schematics.

Andy.

[Dougritt]

Thanks Andy-

I am looking for the electrical connections of the starter and alternator/magneto (I am doing a magneto racing version) and linkages of the carburator.

I coped this over to the SMC Library for all to easily find. Heres the link...
