935 turbo Martini (hundreds of machined parts)

http://img80.imageshack.us/img80/1153/dscn1609ce4.jpgMy

Hallo to all,my intention is to build this model adding all the missing details in the Tamiya kit ,in this I will help me with the lathe and other machines , I will also use other simple materials without using aftermarket parts, the reference pictures I have are from the SMS cd,but many particulars of the real car are missed,a great help comes from the Jacky Ickx fans site and the Gunnar Racing site,the only problem is the really small size of the pictures .


The bodywork was washed,sanded,glued filled and painted with matt white professional spray over 2 coat of flat white primer.

Wooohooo, bring it on fella - I'm looking forward to this one already!:popcorn:

I've always thought this model lends itself to scratchbuild detailing rather than going the SMS route (lovely though their parts are)

If I can make a suggestion on the body for starters please? Cut the oversized rear side window rubber moulding out as the original ran perspex bonded in place with a thin black siicone bead - it also gives you a chance to sand the kink out of the corner shape which is just plain ugly (and wrong)!

Good luck with the build!

After few days I applied the masking using Tamiya tape and Parafilm to realize the front stripe,than painted in flat red.http://img106.imageshack.us/img106/1886/dscn1611tv8.jpg

And this is the result after decaled and 2 layers of Lechler 1K automotive clear.http://img106.imageshack.us/img106/2342/dscn1612ty4.jpg

Wooohooo, bring it on fella - I'm looking forward to this one already!:popcorn:
:iagree:

Welcome! The more crazy maching Italians here the better ;)

Yeah, welcome. Show us what you got. Awesome project. I always envy you guys tackling this one!

I'm confused, you did an excellent job on the body, but if your adding hundreds of machined details, why did you paint the body and leave the molded in hood pins? Do you have more body work to do?

Thank you for the comments,I answer with order ,first in some photos the back side glass has the rubber gasket in others no ,like the wheel covers occasionally used, the continuous changes are normal in a racing car.
The hood pins are aftermarket parts photoetched for the precision, and if I'm not able to draw them in Adobe Illustrator I can't start the P.E. process what I cannot do from myself remains untouched in the original kit.

One of the rear wheels machined,the centers are the inner part of the original wheel machined at the lathe ;the crome has been eliminated with a mixture of water and ammoniac.http://img69.imageshack.us/img69/6010/dscn1738gs5.jpg

And the particular of a inflating valve also machined from a 2 mm TIG welding bar.

the 4 wheels finished ,now is difficult to find a color that perfectly simulates the aluminum to paint the centers of the rear wheels

That looks awesome so far, I will follow closely :smooch:

Excellant work so far!!:)

The shock absorber all machined at the lathe,they are 4 pieces each one,the fillets are M2, the springs have the edges flattned by hand at the grinding machine . Thank you for the comments .

Nice start to one of the best cars in the world.

Excellent, looking forward to more.

Superb start. This is going to be another one of those "must see" WIPs! I can't wait.

Thanks for sharing,
Bill

Wow. Nino, did you thread the ends of those shocks? Did you use a small tap/die?

Murray

Yes,to have a better ride heigth of the finished model all 4 shocks are adjustable
(small adjustments), the rod of each shock must definitely be assembled with
thread locking chemical product (Loctite).The bottom part of the rear shocks is
the original kit shock modified at the lathe as follows in the picture.

One of the disc brakes comletely drilled ,new wheels hub machined at the lathe,
they has a filleted hole of M2 millimeters at the bottom and can be fitted easily
with the M2 screw in the kit

http://img146.imageshack.us/img146/3895/dscn1822hi0.jpg

This is so cool! I would love to have these machines and make these parts. You really went all out on the shocks. I have never seen scale adjustable shocks. This is going to be phenomenal.

this is gonna be one amazing build in such a big scale,

Thank you for the comments,I hope that my ideas will be useful also for you.
In the picture: the brakes with the wheel hubs,a new exagonal nut for the wheel locking completely
machined at the lathe made from aluminum exagonal bar (really hard to find
item in Italy,this one in particular is obtained from a old pen).The hexagonal
nuts that I have used before didn't convince a lot me but now is ok.

Now is time to start with the engine:new exhaust pipes has been machined.
http://img155.imageshack.us/img155/8987/dscn1643ak9.jpg

The motor has received a treatment of painting similar to what is used with
Alclad II, but as final color I have used silver acrylic Vallejo and finally a layer
of automotive clear 1K to seal the color underlying, the washings will be done
at the end. A new pulley set was machined at the lathe,the holes of lightening
are passing through and have been done on the divisor built by me,the pulley
belts are made with a special tape called Letraline made by Letraset.

Nino, you got a PM.

Hi Nino, i take a chair and i look and learn. Thanks a lot. gerard.

Awesome work on making all those parts this is really going to be something special.

Adding me to the devoted followers of this thread.
Fantastic!

Thanks guys, I hope that all this can be of inspiration for your projects.
The pieces for the new starter compared with te one offered in the kit, the small bended rod is a 2 mm TIG welding rod filed and adjusted at hand.

And this is the result after the parts are glued together.
http://img114.imageshack.us/img114/821/dscn1882sd4.jpg

this is awesome work. maybe it's because of lathe, but anyway, this is amazing

The starter almost finished, I turned at the lathe 3 new bolts made out from small brass exagonal bar . Notice the 90° fitting machined in 3 different parts ;I need help to know as the pipelines are connected in entry /exit of the engine and gearbox, thanks in advance to whom can help me.

This is a very special wip. I love the idea that you made the shocks adjustable. The last pic of the starter with the wires is amazing, very realistic.

I enjoy seeing your machining work as well as the level of details on this car! Fantastic progress!

I totally agree with Les, great job on this model.

Wow, those fittings (from the hex bar) look great. I have to say that I've been trying to make something like that on my own lathe (from small hex bar), and am really struggling. The thin/small brass just isn't strong enough to handle the machining (at least the way I'm doing it....). I have it really close in to the chuck, but still struggle.

Is there any chance you might do a mini-how-to on machining those? Tools/bits you use, pics of your setup, etc, etc? How big is the hex bar across the flats?

Very nice work. Thanks for the pics and updated. Checking in everyday hoping for more updates!!!

Murray

:eek2: I'm just speechless. Amazing how much fine and great detail you're putting in this build. Keep it comin'. I'm a devoted follower of this thread.

Shovel a.k.a. Mark

I just dont know where to start, to say Im speechless is an understatement!

I WANT A LATHE NOW! oh and for about £50 too, anyone got one they dont want? :iceslolan

Seriously though, beautiful work, this is definately going to be 'one of those threads'

Very nice work but I also like teh color you have achieved on the engine block :thumbsup:

anyone got one they dont want? :iceslolan
...or two? :)

----------------------------------
Hallo the exagonal brass bar is 2 mm for the fittings and 1,5 mm for the stud bolts/nuts but other size are available in Italy at this page:http://http://www.utensilirevelli.com/profili-di-ottone-profilo-esagonale-pieno-c-98_109.html
Murray I have sent you an e mail regarding your needs.
Thank's to everyone for the comments.

Another kind of fitting (3 pieces) and one of the pulleys for the injection pump.

This is Sick!!!! I love the detail you put into this!!!! I will watch until it's complete!!!

I'm back... with a handful of new pieces to detail the injection pump.
http://img162.imageshack.us/img162/4518/dscn1985lp5.jpg
Someone can help me with the passages of the pipes in the engine area?

This will be an amazing engine once finished !
Great machining !

New stud bolts and nuts has been machined,and glued in place,each arrow indicate the position on the engine

Scroll through the photos, in the mid-section there are several shots from 935 engines, behind the pics of the green 911.
Hope it is useful!:grinyes:

Thank you, I have almost downloaded the available , I have to study the pictures with calm.

The first handful ..of fittings glued in place: every arrow indicate a different piece machined from thin hexagonal bar

Man those little fittings are sweet. Nice work. I've been trying to make some of these on my lathe, and it's not as easy as it seems.... (at least for me...)

Murray

For me it is very simple let me think.. 5 minutes every piece. Being all equal pieces, once done the first one the other ones are so easy to turn; I recommend for this kind of machining a good pair of glasses as those used in philately: I use a 2X magnification lenses and my eyesight has appreciated.
If you want send me images of your set up and I can tell you what to do.

The second ..handful of small fittings glued in place, I'm not sure of the correct name of the 2 intakes,Tamiya instructions speaks of " inter cooler" but I don't understand how they can exchange the heat in the boosted air from the turbo to the engine.
I need help,I have lost the copy of the 2 instuction book included in every SMS superkit,the most important for me is the 8 page full color, for the schematic diagrams that are inside: can someone help me?

I don't understand, you don't understand how the intercooler functions to cool the air or you don't understand how it would work in this application?

Hi Nino,

Everthing you ever wanted to know about the detail kit and some diagrams.

Uli

Very nice work, Nino :thumbsup:

Those fittings you are making are perfectly suited to this model. They add so much life to the engine not to mention realism. They look completely functional.

Great work, those little fittings are excellent.

Thank you for the comments; If I had the schematic diagrams everything would be easier and without incomprehensions: in base to my deductions this engine didn't have an intercooler, I made reference to the name in English language that Tamiya brings in the instructions of the kit, and what they call inter- cooler are the 2 intake manifold ,if I am wrong please correct me.

This 935 features two water-to-air intercoolers (the two big boxshaped thing on top of the intake trumpets). The water of the intercoolers is cooled by radiators in front of the rear wheels. Top notch work by the way!
