Hi,

 

First of all, sorry for the (very!) poor quality pics...
I will try to make some better.

 

Brake calipers and the stub axle (?) were chemically burnished.

dsc08515.jpg

dsc08516.jpg

dsc08517.jpg

dsc08518.jpg

dsc08519.jpg

Brake calipers were "stolen" to the M19 in order to replace those supplied in the kit.

rear axle parts are prepared and drilled... too much drilled!
I had to play with the low temp solder in order to fill the hole in the lower part, then sand, but now it's ok.

dsc08521.jpg

dsc08520.jpg

dsc08522.jpg

dsc08523.jpg

Brass knobs for the dampers.
Same method than those done for the Ferrari 312F1.
They will be burnished.

dsc08524.jpg

Primer and paint for everybody:

Hi,

Thanks Chris.
This is just a light chemical treatment that can be done by everyone ;)
You can use Blacken'it to oxidize the parts.
If Blacken'it is not available, you can use the product provided by Uschi Van Der Rosten or Master.
You just have to dip parts into it, wait, rince and brush them. 

Few progress.
As usual, radiator is filled.

dsc08530.jpg

dsc08531.jpg

Better pics than those from yesterday:

dsc08532.jpg

dsc08533.jpg

Weld lines added.
It's a bit rude for now, but with primer and flat black it should be ok.
If not... I'll undo it and will make the weld lines with the iron as it was tested initially.

dsc08534.jpg

dsc08535.jpg

Dampers almost finished.
A Koni sticker was added...
Just now need a light oil wash.

dsc08536.jpg

Primer and paint session .

dsc08538.jpg

dsc08610.jpg

dsc08611.jpg

dsc08612.jpg

dsc08613.jpg

Front dampers clear coated:

dsc08614.jpg

Not that happy with the weld lines I find pretty rude and out of scale...
I will decide what to do after "weathering" job on this side exhaust.

 

Update on the Gearbox/Engine assembly and test fit: cooool!

Time for pictures:

dsc08615.jpg

dsc08617.jpg

Maybe I will do something like that for the weld lines:

Those dampers look good! Just like the øhlins I put on my Miata.  I really like the hardware on the suspensioon joints. I look forward to the completed car.
