The chassis from aluminium
Hello. I live in Belarus in the city of Minsk. I always very much was interested in automobiles Super Seven, and at last have decided such to
construct. Unfortunately I live very far from England and to get ready Kit from England - very difficultly, and transport charges come nearer to cost
Kit-car. Now I deliberate above construction of own chassis. Has found on the Internet many drawings. All of them for the chassis from steel. Whether
somebody built the chassis of aluminium? There can be someone has drawings of such chassis?
I shall be glad to any advice(council) and the help?
For it is earlier grateful,
Alexander
PS I Ask the application for my English.....

Doh! 
Do a search, its been covered 100s of times before on here.
A spaceframe isnt suitable for contructing from ali for many reasons. Low strength and fatigue being the 2 main ones. I cant be bothered to go into
lots of detail again!
Make it out of steel, it only weighs about 80kg anyway.
Cheers,
David

The question of aluminuium being used for chassis construction has been well discussed on this forum.
The general consensus is that it is not a good idea as it will not be very long lasting as fatigue in the joints and suspension mounts could be an
issue as the miles rack up.
Steel is generally thought to be the preferred material although Robin Hood have started making the lightweight kit which is an Aluminium chassis
Have a look here http://www.robinhoodengineering.co.uk/Bolteon.htm
Hope that helps

Hello, and welcome!
You are correct: the chassis for seven type vehicles is normally made from steel, as Aluminium suffers fatigue, and can break after time.
As FlakMonkey says: make it out of steel, as the lower strength of Aluminium will mean making it out of thicker material, which will increase the
weight, so the amount of weight you save will be small.
Hope this helps,
Ed.
P.S. For reference, steels are 7800 KG/M^3, pure Aluminium is 2700 KG/M^3.
I-iii-iii-iii-ts ME!
Hurrah.

Looks like we are now covering all 4 corners of the globe now
To answer your question if you do a search on here you will find that this idea and the pro and cons have been covered before.
The general concensus of opinion is that it's really not practical to use alu for a sevens spaceframe.
Who the f**K tightened this up!

Very much, very much, it is very grateful.
Thanks for the answer.
Recommend, please, drawings of the chassis. Those drawings which it is possible to take and build safely the Locost.
Thanks.

Who knows, what it is the automobile who it built? Or it built on Donkervoort?Image deleted by owner

That pic is of a Donkervoort. Good if you have the money I guess.
The McSorley plans (link on the links page of this site) are the best ones to use to build the chassis apparently.

Thanks, David.
I shall necessarily study these drawings.
I have visited your site. I liked your work.
It is glad for you, Success.
Alexander.

Is Estfield not more in your region?
Or I heard something of a kitcar manufacturer in Finland.

Have a look in the running gear section for plans from Rorty for both IRS and DeDion to fit the standard chassis and Sierra running gear

Lada has been done by at least one builder who has built several chassis --- no major problems apparently

Lada - not the best automobile as a whole.
Now at me a problem with wishbones. I yet have not found their drawings. Also I do not know as they incorporate to a nave of a wheel. In the Internet
I have found drawings of the chassis with a dependent back suspension bracket. I search - independent, while for it for me a problem.

Hi Ruders,
You need to buy the locost book:
http://www.amazon.co.uk/exec/obidos/ASIN/1859606369/qid%3D1139926895/202-3477024-6266263
That'll give you the plans that we all use for wishbones, chassis, etc. etc. Just use the McSorley plans to correct the chassis plan mistakes!
Cheers,
James

Interesting that. I wondered what happened to all the rusty old Ladas. Like why the Russians started shipping them back to Mother Russia. A Lotus
Riva is possible then.
Also think of the potential weight saving. Junk the starter motor and battery and replace with the starting handle.

Do not underestimate Laa 1500ccm has 80HP and if you lighten the flywheel and put two carburators it will run very nice. That is Fiat engin maybe old
but stil fiat.

I long pottered with motors Porsche 944/924. I saw their design, I assorted them and collected the hands. And now in my garage it is possible to find
a heap of details from these motors. And consequently I know, (I think, that I I know) what should be the motor. It is exact should not LADA! Racing
motors LADA - are very good! But their price is very high. And it is completely not similar to factory motor LADA. Besides I test sympathy to mark
FORD. My the first car was FORD Escort 1.6 xr3i 1983. It was the delightful automobile. At us in the country strongly underestimate mark FORD. It
count budgetary and confused, completely not sports. I want to prove the opposite.

The Fiat 124 was delightful car to drive --- it would disapear into a pile of rust in the UK climate within 2 years and had dogey itailan electrics
but it was lively, handled a treat and very nice to driver.
The Lada was in theory a toughened up 124 but had none of the joy of driving the the 124 had, the bulid quality was truly awful and the materials used
were substandard.
Only thing worse was the Polski-Fiat 125 that was a contender for the worst car in the world award along side the Zodiac Mk4, Chrylser 180, Austin
Allegro.

Yup the Lada was truly awful and the FIAT not half bad. Steering worst thing on Ladas. Not rack and pinion. Lada should have left original design
alone.

Hi
I'm the proud owner of a Locost7 Fireblade with an aluminium chassis.
The chassis has been rock solid for the last 5 years without any signs of cracking.
When I built it I had everyone and their mother saying it would not work....it will crack (it has not), it will bend(no), it will be hard to make(it
was easy)...you get the picture.
The chassis is taken directly from the original book design with some strengthening around the suspension mounts. The Fireblade unit is mounted
rigidly with an FR2000 reversing box in the tunnel.
I have had one or two small problems with attaching items like body mounts and fixings to the chassis. I welded on small tabs then bolted things on to
them, a couple of these tabs have fallen off due to fatigue cracks.
The chassis has been periodically crack tested without incident.
Julian
