WOW - just plain WOW ! Malc your contributions are gold for all of us.

By chance were you an F-1 team member at those times??

Haha, no, don't think my Dad would have let his 12 year old loose on a 312T in 1975! Much as I would have liked to...... Hence a career as a powertrain engineer.

Good to help out fellow F1ers, its a small corner of a niche hobby!

Haha, yes I had forgotten, nice little project for vacforming/plunge moulding.

Don't have access to vac or plunge...although...strangely enough...I was a specialist vac former for three years...made all the signs for Burger King and Sainsburys across the UK in that time!

Hi Chris

just had a look and now only direct from Shapeways (whom I have used a number of times)...and not a bad price...thanks for that :)

 

 

Vac former I operated took a sheet of material 3 mtrs x 2 mtrs...so yes...big boys stuff.

All those pictures talk about a very different formula one race cars world than today...
It smells hot oil, too hot brakes. Makeshift mechanic seat, another way of life, far from today clinical atmosphere!
I do love that, thanks for sharing.
Ron, your work is admirable, congratulations.

@Malc2 beat me with the photo's! And I agree with @PROPELLER about them depicting another age, can you imagine Lewis's chief mechanic working on an engine balanced on a wooden pallet?

I think the only one I can add is again from Long Beach 1976

When I built my model I considered the Shapeways items but they seemed a bit insipid to me and pictures seem to show the ducts in quite opaque colours so I went for this

So I'm sure with your painting techniques Ron you can do something MUCH better.

Glad you like the work so far Dan.

With the help from Malc...Dave and Chris...I now feel more confident in my approach to this build...indeed...all the input this evening has given me a better all around focus...and the drive to push myself a bit harder.

Regards intake shroud...not included in kit

 

I was very surprised by this as well Ron but I could find no way of reproducing this to my satisfaction so it remains missing on my model. If you come up with a solution I would happily pay for a pair as it's one thing that bugs me about the model! Although I now realise I too missed the roll over hoop - my car depicts the 1976 Long Beach race - how did I not put 2 and 2 together?

Thanks for great pic Dave...huge atmosphere in a simple picture from a time gone by...when racing meant man against man...and not technology.

 

Your brake ducts are stunning...if mine are half that good I will be very pleased indeed.

I have pondered this from day one Dave...and have been playing with some ali sheet (easy to form)...but that again raises the question of how to make it look like fibreglass...one idea being the old trick of tumble dryer sheets...although...I could send them to you...to repeat the finish on your brake ducts LOL

After tonight's input from you guys I am glad I made it...and will fit it...along with the ali one I am making for the rear...to replace the kit plastic parts.

If there's one person I know who can create the required texture and colour of these parts it's you Ron, you'll nail this Ron no problem.......nice work so far by the way 👍

No pressure for you Ron.....why?.....because you would have seen this problem weeks ago and planned accordingly 😉

Ron, 

When I did the brake ducts I textured them by giving them a good coat of liquid poly, leaving it for a minute or so then stippling with an old cut down paint brush.

I used this method on the Porsche 935 fibreglass parts as well, it seems to work well and is not as uniform a texture as using a paper overlay. Any large lumps can be gently sanded down and it holds washes and highlights well.

But I'm sure you know all this!!

Ok...so you know me too well now...it is something I have thought long and hard about how to achieve...and...having now got some airbrush primer...I hope I will be getting to grips with in the coming week.

Appreciate the insight Dave...and not a technique I had in mind...but then again.......

Thing is...in several of my ref pics...they are actually very smooth on the outside...

Your idea would work on the inside tho mate...nice one for planting the seed :)

There is an old figure painters trick to giving the illusion of translucency...which I will try and...if it still works...I will post how it is done.

 

Much appreciated for the input fellas.

Ron, your paint techniques plus a heavy coat of clear will work. I might stipple color on with sponge then clear to near gloss. The originals were only glass cloth (not too heavy weight) bonded with resin and gel-coat.

+1 although i'd go semi gloss max, with matt areas from dirt/grinding smooth etc

Made in 2 half moulds, so outside is smooth, inside is rough: old glassfiber strand not always laid down perfectly in difficult areas, so after resin was set, little smooting with sandpaper/angle grinder was normal & necessary: one could easily get hurt on the sharp edges & spikes of fibre/resin. 
You can see the two halfs being joined top & bottom and then joint got smoothed out. I think the 2 outer dimensions of part A & B to be the same because easy to force into each other, the inner structure would have bigger size on 1 part for easy assembling. I think .

It might be nice to reproduce inner rough surface using some clear & real fibreglass strands (easily unrafled into individual 'wires') added into wet paint. If fibreglass wire too thin, one might even try real hair. How nice would that be: the only time you don't need to worry there's a hair in your clear 😉

It looks like middle one in pictures is differs compared to others. Much thinner side wall, & less wide traveling area for steering rack
