More work on the subframe.

Image]
Starting to look like a subframe again.

Image]
On this side the transmission goes over the lower support. It still needs more upper supports. I need a mock-up transmission to finish this. Matt ? :razz:

Image]
On this side the lower support needs to go around the engine pan. So I put the lower suspension on so the lower support will miss it to.

Subframe almost finished. Got some crappy pictures. :blaaah:

Pictures deleted to make room for better ones.

I took it outside to get a better picture, and got a worse one. Go figure. Maybe that red reflector messed up the focus.
I'll take better pictures.

Found the transmission, it's heavy!

Image]
I painted the subframe so if it rained it wouldn't rust.
I'm trying to get the transmission in position.

Image]
This is close to the right position. does it go up, or down?

Image]
Is this right? it almost touches.

Image]
I had to cut the bottom rail, and i think I will need to cut it some more.

sort of mocked up.
I'm tired of working on this, I think I will work on the suspension.

Any new updates? Or did you burn out with all the updates in March? :)

Funny you should ask.
I finished the stiffener and got the rear wheel on.
Now I need to finish the hubs and, bolt them on, and put the front wheels on, and it's a roller! :cheers: :cheers:

Some progress?

Crossmember in place. I angled it to clear the seat.

Modified Triumph seat rails.

Image]
Seat bolted in.

OOO! it's tipped back too far. I'll have to modify the crosmember again! :furious:

Cool project and nice progress. 8)

I had considered doing something similar with a Metro/Swift engine though I was planning to place the engine/transmission (with a locked differential) behind the passenger compartment and drive the single rear wheel. I figured if the weight could be kept down, as well as power transmission loses, and keep the aerodynamics fairly clean, it should get close to 100mpg.

There was a kit car in the late 70's that used the rear end of a motorcycle and the front suspension of a VW to build a 3 wheeled door stop shaped car.
It was very efficient and was supposed to handle well. They also had a special tilting front end that would let the entire car bank into turns. I think the motorcycle drive train would make a better gas mileage car since it has much less drive gear. The engine would have to be de-tuned for efficiency since most motorcycles are set up for performance. I was thinking about the possibility of using a geo front end for a 3 wheeler, it would probably be good for performance, but I think the mileage would not be much better than a normal geo/swift.
If you used a motorcycle like a honda 500 v-twin and detuned it with a single carb and hot ignition, it should be fairly easy to get over 80mpg. with reasonable performance.

johnsn,

Yes, they always seem to have something more important to do, don't they? :lol:

-----

3play,

I think you are referring to the Robert Q. Riley's Tri-Magnum that was featured in Popular Mechanics back in the 1980's. http://www.rqriley.com/tri-mag.html

I had considered using a motorcycle engine/transmission. The problem I saw with this solution is the durability of the transmission and clutch, not to mention that neither torque nor fuel mileage are priorities with motorcycles. Another thing to consider is the charging system of most motorcycles isn't up to the task IMHO. A two seat, three wheeled vehicle is going to be quite a bit heavier than the MC. Unless one wanted to replace the cams and alter the ignition curve, there isn't a lot of torque to be gained.

Another consideration is the intial cost and maintenance costs of a MC powertrain. They tend to require more frequent and more involved procedures and they are more expensive up front.

FWIW, I owned a 1982 Honda GL500 Silverwing and it was no torque monster. It made acceptable power once you revved it past 5000 RPM (10,500 RPM red-line for a pushrod V-twin 8) ) and only got 48-50 mpg when ridden easy at 55 mph and less. The lack of 6th gear in the transmission didn't help any. The engine/transmission with all the goodies (radiator, ignition, ect) was over 175lbs.

As for the potential for high fuel milage in a Metro/Swift 3cyl powertrain. I think that a light weight (sub 1000 lbs) vehicle that is geared for the weight and is designed with aerodynamics in mind should be able to reach 100 mpg fairly easily.

If 75mpg was possible with the vehicle in the following link, I figure there was room for improvement with a clean slate as far as the chassis. http://www.1989geometro.com/

Voynik,
Quote. Yes, they always seem to have something more important to do, don't they? end quote
Don't you know it.

Image]
I shortend up the seat mount.

Image]
I also shortend the seat adjuster.


I narrowed the cowl of the car. when I did it the center came to a point. This looked cool so I left it.
In setting up the seat I saw the point would be in my line of site.
So I'm removing it and reshaping it.
OH joy. Image

Image]
I cut out the dash and cowl.

Mounted the left door.

Image]

Once I get the other door on, I can redo the cowl.
I'm going to tip the top of the windshield back for aerodynamics and looks. Edit: didn't tip the top of the windshield back. Couldn't figure out how.

Let's see, I put the right door on.
I cut the spot welds out of the window surround, cleaned and welded bits together to make the windshield surround.
Welded the old cowl back together with no point and clamped it on with new corners.

Image]

Then I trimmed all the cowl parts and welded them up.

Image]
Now I have a cowl. It fits pretty good.
The only problem is the left fender feels too short. I'll have to do some measuring.

I got the seat mounted, and chopped the wind shield posts some more.
Ended up with about a 4" chop.

Image]
Something is wrong! :huh:
The orange level is level.

Image]
This orange level is not level! :furious:
The long level is on a 1.5" spacer to make it level.
This is the first time I've had it out and uncovered. I noticed it's low on the right side. Image
ImageImageImageImageImageImageImageImageImage
NOW I'M IN TROUBLE!
ImageImageImageImageImageImageImageImageImageImageImage
What a dummy.

:thwack: :blaaah: :dunno: :censor: :oops: :oops: :cry: :? :( :vibe: :buzz: :huh: :thwack: :cry: :cry:
I'm stuck.

Started to cut it up. :ez_mad:

Image
Cut the right cowl and windshield post away.

Image
Removed the door surround sheet metal.

Image
Cut through the inner sill.
I leveled the sub frame. Now I will try to get the cowl in straight.
I'm depressed.
Any encouraging words?
john :(

Remember

It took a hell of a lot of professionals to build the Titanic
It only took one amateur to build the ark (and he had few hassles and set backs)

Don't give up, see it as a minor hiccup for you to learn from .. from what I have seen along the way you have done more than many will do in their lifetime, leave it now and you will regret it.

Thanks guys, I feel better.

I think the cowl was bent from the start, so I will now measure from the sub frame.

Image
This is what it was like.

Image
This is what it looks like now. The cowl is now more level now.

I think I will cut the cowl completely off and align the right door to the left door, and then put the cowl back on.

Wish me luck.
john :D
