Congratulations

I'll add my congratulations and admiration to the others. This is a build that will be remembered for a l-o-n-g time.

Hello everyone,

Well, the weather stayed kind to me this morning and I was able to take the 908 outside for a photo session - as promised, I've posted a new thread in the 'Completed Projects' sub-forum:

http://www.automotiveforums.com/vbul....php?t=1074343

I thought it would be a good idea to bring many of my references together in one place - I know I've mentioned this product or that product throughout the build, but here's a summary of what I've used:

styrene tube, etc - Evergreen Scale Models
styrene hex-section - Plastruct
fibreglass cloth - Deluxe Materials laminating fabric
fibreglass resin - Aeropoxy, from Deluxe Materials
Acrylic rod - Clear Plastic Supplies
suspension ball-joints - Radio Active

3M blue Fineline masking tape from Everything Airbrush
spray primer - Humbrol acrylic (grey) and Vallejo acrylic (white)
topcoats (supplied by Express Radiators):
BS 18E50 Ribbon Blue

Thank you all for your comments and feedback throughout the build, and for your compliments now it's finished: much appreciated. The next project will certainly be a challenge - I'm taking on the 935-78 'Moby Dick', again in 1/8 scale, again fully scratch-built...

Have a good week,

SB

You have been a very good teacher for me with this project. Completly amazing!!
Congratulations!!
I will follow your next project, of course!!

[Pascal D]

Stunning absolutely stunning !!! I've followed this thread from day 1 and I still find it amazing how you manage to build so accurately.

You must feel larger than life after completing such a fantastic project.

Can you book me a seat in the front row for your next build ?

Sincerely

Pascal

SB, please forgive me for resurrecting your thread, but I am currently in the process of rebuilding a digital version of the 908/3 doing textures (since I'm no modeller). And I'm stuck with the buttons / labels on the dashboard. Do you have a wiring diagram of the dashboard or can you at least let me know what the switches and warning lights are for? From the reference images I have I could only get the following:

From left to right I have:
switch "???",
switch "???",
switch "???",
switch labeled "(something)..Pumpe",
switch labeled "Ein/Aus",
starter button "Starter",
warning light "???" (yellow),
warning light "Benzin" (amber),
temperature gauge,
rev counter,
oilpressure "Öl-Druck",
warning light "ALT" (green),
warning light "Öl" (red)

Thank you

[ScratchBuilt]

From the reference photos I used for the Targa-winning car, I had the dashboard as follows (driver's left to right)

3 black switches (2 must be ignition switches, not sure about the third)
1 red switch - fuel pumps
starter push-button
yellow lamp - low fuel warning
red lamp - oil temperature warning
oil temperature gauge
rev-counter
oil pressure gauge
green lamp - oil pressure warning
red lamp - alternator warning

I'm sure that other 908-3's have slightly different combinations of lamps and switches - I've seen the green and red warning lights swapped over on other cars, for example. For a lot of the wiring I used the diagram shown in the 'Porsche 917 The Undercover Story' book to try to make sense of what was going on! Having the text in both German and English was useful, too.

I'm struggling to remember what the extra black switch was for - given that the 908-3 didn't have headlights, illuminated numbers, or much else in the way of electrics. It'll probably be something obvious - I'll dig through my notes and have a closer look at the photos, and see what I can find...

Hope this helps,

SB

Thanks for the feedback SB, much appreciated!
I've done something similar for a 917/10 a year or so ago. There were 6 switches in 2 rows of three (left to right, top, bottom):
fuel pumps 1, 2+3 ("Pumpe 1, 2+3"),
ignition circuits H1, H2,
ignition circuits V1, V2 ("Zündkreis H1, H2 and V1, V2")

From your description I can take the labels for the warning lights. As you said, the car I used for reference has a slighty different arrangement - I was missing the obvious oil temperature warning. From what it looks like "my" car has the warning lights flipped inside out, but otherwise the arrangement is similar to yours.

That aside, as you indicate, I have seen several different switch and warning light combinations for 908/3s. Sadly I have yet to see one in the flesh. I've seen a number of 917s but no 908/3. And I was lucky to see the 16cyl 917 prototype engine in Wolfsburg's "Autostadt" exhibition last weekend - what a monster. It looks like 2 8cyl bolted together though - I would have expected to look like one giant block as on the Auto Union Type C engine (also on display there).

I was watching some Porsche 936 videos on Youtube, and it made me think of this kit and if you had ever finished it; and you have! I know I signed in to bump a 2 year old thread, but this sort of work deserves that. A very belated bravo!

Absolutely inspired by this story

Although this thread is a from a while ago was hoping somebody in here would be able to help. I am thinking about a similar project for a porsche 906

Really love this car as it was street legal as well as a great track car. With only 50 made - way above my budget to own one.

Any advice where I could get fairly accurate drawings to get started to build the chassis?
