micro car chassis
smart51 - 4/4/08 at 01:41 PM

Here are some pics of my new chassis before I strip it down and paint it. Before anyone asks, yes it will fit out of the door. The top of the chassis isn't welded on yet and will be welded when it goes out to the garage to be built up properly. Rescued attachment chassis.JPG

I've estimated that the whole thing will weigh 275kg when finished. I'd be happy enough if it ended up weighing 300kg. I expect 90 MPG too, which makes the Prius look expensive and pointless. Rescued attachment chassis front .JPG

Now I've got to strip it down and finish off all the welds. Rescued attachment chassis rear.JPG

Are they patio doors on your garage, or have you knackered your living room?


Mr Whippy - 4/4/08 at 01:50 PM

oooooohhhh this is the scooter thing

finally we get to see it, What's the body going to look like?


smart51 - 4/4/08 at 01:51 PM

No, that's my basement / workshop. It saves working outside in the winter and stops unpainted steel from rusting. The car will be built in the neighbours' unused garage at the bottom of her garden. I get to use it in exchange for trimming the hedge that joins her garden to mine.


Benzine - 4/4/08 at 01:54 PM

Awesome. I'd love to build something similar one day aiming for high mpg


wilkingj - 4/4/08 at 02:30 PM

Oohh

From the VDLA site:
http://www.direct.gov.uk/en/Motoring/OwningAVehicle/HowToTaxYourVehicle/DG_10012524

Tricycle (TC50), any cc, UNDER 450Kgs... £66 per annum Road Tax as well.

and 90mpg.. Bugger, you spotted a belter there.

good luck with it.


Dangle_kt - 4/4/08 at 03:48 PM

why have you used scooter tyres? surly all the wear will be over a very small contact patch, and so you'll square of the tyres quickly and have to change them regularly when they loose all useful tread?

Unless the wheels articulate .... like that new scooter thing?

very interesting 3wheeler project, is this going to be a cabin scooter or other ?

What engine are you using ? engine displacement ?.

Yes, a cabin scooter. I'm using a piaggio x8 250cc engine and transmission. It makes 22 BHP and is fuel injected, catalytically converted and is EURO3 compliant, which should make MSVA a bit easier.

Nice.......I was thinking of a similar project a few years ago, but never got to building the thing.

Do you have a build blog?, it would be nice to follow your build.
Looking forward to seeing it finished.

Cheers

I was toying with the idea of getting an electric golf cart on the road, and had found a damaged one for £400 - which was about £300 more than I wanted to pay for it

Increase the voltage, change the gearing, put on decent brakes, lights and (removeable) windcreen. Fit solar panels on roof, and an alternator to the brake pedal

Might build a T or a



next anyway!

Hi smart 51.
I have been very interested in your project and the use of the Piaggio engine unit.
We have just bought a piaggio 400 scooter to try something similar so forgive me if I try to pick your brain over one or two things.
first off we propose to use the whole rear end including the frame and just cut of the tubes in front of the engine, the tubes are very substantial and strong.
Q .. have you used the frame as a starting piont.?
Q..How are you aranging a hand brake?
Q.. Are you altering the exhaust as the one we have makes the arse end very wide?
Thanks for any info.
Regards Kipper


smart51 - 28/5/08 at 05:35 PM

I haven't used the bike frame at all. The engine is attached with 1 big bolt and the dampers with 1 normal sized bolt each. I decided to make my own chassis that was a bit like a locost chassis.

I considered using a gokart cable operated brake calliper on the rear disc for the handbrake. There are unused bosses on the scooter's trailing arms that could mount a bracket to hold the calliper. In the end, I fitted handbrakes to the front wheels, thinking that two are better than one.

I've left the exhaust unmodified. It is euro 3 compliant so should make SVA easier. My design seats 2 abreast so even with a tapered rear, there's room for the original silencer.

What are you building? Any pics?


kipper - 29/5/08 at 11:18 PM

Hi.
Thanks for the reply. We are buiding a three wheeler using the Piaggio 400cc engine unit and rear frame assembly, for the front end we are using a locust front end and the ladder frame chassis which will be shortened as the engine bay will not be needed. The peddle box will be just behind the front wheels.
we dont have a plan for the bodywork yet, we will see what we have when the trike is rolling. something like a lotus elise front clamshell would be nice as a starter.
The handbrake is still a worry though but I guess we will get over that problem.
Regards.Kipper........AKA Denis.

Any progress updates on the three wheeler project

I've been working away on the inner fibreglass panels. Its still looking quite rough at the moment because I plan to do all the finishing in one go. Better not to tidy up part of it then drop something and scratch it.

I even drove it today. 2 metres, from the back of the garage to the front. It was so good, I went back and did it again. Rescued attachment inner tub.JPG

The car has a roof and a boot and everything. Rescued attachment boot space.JPG

smart51 - 12/7/08 at 02:48 PM

I had to take it out of the garage (my next door neighbours) whilst she had a fridge freezer delivered, so I just had to take it up the lane that runs along the back of the houses. It power slides like a demon up wet grassy / muddy slopes


Delinquent - 16/7/08 at 12:06 PM

You see those blokes with white coats on coming up your driveway...


ceebmoj - 1/8/08 at 11:32 AM

hi there,

what are the wheels at the fount? thay look like rear wheels from a scooter if so what hub / upright are you using with them? does the scooter have a bolt on stub axle at the rear?

any pictures greatly apreasheated.

Blake

They are 10" wheels off a mini. I'm using mini brakes hubs and uprights too. The rear wheel is part of the scooter's engine and transmission. I haven't touched it at all, it was simply unbolted from the scooter and bolted on to my chassis.

Here is a "beautifully" rendered drawing of the car as I intend it to look. I now have to transfer this to the foam. Rescued attachment MinimaCabinScooter.JPG

Nice!

Just a clean design, what else do you need?


Delinquent - 11/9/08 at 08:46 PM

Looking smart Smart

hope you don't mind I've U2U'd you a very quick Q on MSVA.


Aboardman - 20/10/08 at 06:18 PM

wow that is just the type of project that a few (4) of us at work are going to look at,
1 is a structural engineer (the leader)
2nd has a degree in aeronautical engineering,
3rd has a degree in automotive engineering,
4th me,
have you any more details/drawings of your project,

thanks

There are a few pics of the bodywork under development here: Link to bodywork thread

The intention was 2.5m long, 1.2 high and 1.295 wide (to sneak in under the 1.3m width that makes the car lighting regs easier). It will be slightly longer at the front to give clearance to the headlights and at the rear to make it look nicer.

It is also not quite as tall due to a slight error making the roof!

I'm pretty sure that is the car I drew on my history jotter in 1970

I'm working on something similar myself here in Italy, but I'm still undecided on the bodyshape.......

The dimensions would be similar, as the rules for motorcycles homologations are pretty similar in Europe, and I want it to be considerd a motorcycle with an extra wheel.
