Re: MFH 911 Carrera RSR Turbo
super nuts model. Love it.
But... too many copper nuts/bolts to reflect reality. I understand choice if going for color contrasts, but appart from temp sensors, i never found any bolts in copper/bronze on cars. Must admit: don't know anything about race cars, but i'd be surprised if.

You find yellow anodized or nickel plated screws and parts on a lot of Porsche cars, even the older ones had them, to me it looks very realistic.
Take a stand!

Re: MFH 911 Carrera RSR Turbo
agree with Guido ! I've double checked this at the RSR exhibited in the Porsche Museum. The bolts have a brass/silver look alike color, which is according to the Museums staff periodically correct. The bolts on my model have been painted with a Alclad Brass/Silver blend to imitade this look

Ah, yes, i know these, but i remember them to have more yellowish/golden/silver/areas mix.gp-models wrote:You find yellow anodized or nickel plated screws and parts on a lot of Porsche cars, even the older ones had them, to me it looks very realistic.
You could buy them per kg, low value & low strength bolts & nuts. Maybe they 're also available 8.8 & up, ok.

Re: MFH 911 Carrera RSR Turbo
great so to see things come together Uli. And thanks for the insight considering Etching all.
The screws and bolts Wim mentioned look to me as passivated(sometimes translated als passivised). It is a similar process to galvanising(grey flocking as a surface finish) but with electric current instead of heat. Also called 'electric galvanising'. The quality and thickness of the steel have an influence on the colour, as well as the current and duration of the exposure to electric current. This whole process leaves a goldish, greenish, purple tone as an almost natural protective layer. Hence the colour differentiation. As far as i know electric galvanised steel can be passivated yellow but also in other colours as a result of the substance in which they are submersed.
The whole process is a relative cheap method to protect/seal steel with a minuscule layer-thickness. Chrome-6 used to be used for this here in the Netherlands, but thats banned because of health issues. downside of electric galvanising is that the quality of the protective layer deteriorates quite quickly in relation to thermal galvanising for example. One of the reasons they where used on temporary structures/objects(?) I think.
Anodizing is a process of activating the surface to transform into a natural protective layer, but as far as i know, only applicable on aluminium/aluminum. Here pretty much al colours known to man can be created, If pockets are deep enough.
Sorry for the text and likely flaws; only have basic knowledge of materials my job requires me to have. Great to see different techniques to mimic or even recreate 1:1 materials.

Re: MFH 911 Carrera RSR Turbo
Hi everyone and thx for your continuous interest !
Jesse, thanks a lot for your detailed explanation of the process on how to passivate/galvanize parts made of steel. I remember when I was a student and working during semester break in a company who run a galvanic operation doing exactly this.
On the RSR project, I could in the meantime install the fuel tank, which is covered by etched parts to replicate the sheet metal of the real car. Likewise, the "cage" is fully assembled and test fittet with the chassis and bodywork. Fit so far is looking good ... no rework required
Test fit of "passenger" seat. The seat is covered with a lady sock and hand painted with a brush to replicate the GFK texture
Spark boxes installed and wired
Next update will be when I've finished the Dashboard.
BR, Uli

Re: MFH 911 Carrera RSR Turbo
Awesome work Uli, the seat looks perfect, color and texture looking great!
It`s coming together slowly, feels like watching a restoration of this car, like that!

Re: MFH 911 Carrera RSR Turbo
Hi there, it's time for an update about building the dashboard.
Before switching to content, thanks for your nice comment Guido ! Indeed, in these kind of "monster" projects, you basically reverse engineer the original car (provided you have good reference data and pictures) ... personally speaking, the research and design part is the cherry on the cake for me when conducting this beautiful hobby.
The MFH kit parts for the Dashboard are nicely done but are also lacking some details. At the end, I've decided to only use a few of the kit supplied parts and fortunately, Michael of MWT was thinking the same and has provided me with some of his own designed and 3D printed RSR parts along with his new decals. Complemented with my self designed/manufactured parts, the dashboard assembly become basically a model by it's own.
This is the main dashboard part as supplied by MFH:
First step was to sand off the raised switches and instrument rings and to cut off the areas, which will be replaced later with new etched parts:
This picture provides an overview about the individual parts (w/o decals) to build up the refined dashboard assembly:
During the build process, the partially assembled dashboard had to be test fitted to ensure that there will be collision later with the cage:
The final result temporarily installed in the car:
Thanks for watching ! Next update will be about finishing the interior.
