kinnernet - Moto Tank

a seperate control for each bike to get seperate right/left control like in a Tank steering.

I looked for a scooter engine (small & automatic) and got this DUKE 150 from FREE from a friend (Thanks Chaim!)

This was just a test to build a "Harley Davidson" type scooter...� I was looking for a cooler machine !

BUT.... instead of just 2 wheels to have 2 seperate controlled ENGINES & Braking systems

Here are the 2 engines side by side with a BEACH chair (just to check the concept)

after few weeks of work, you can see the bikes attached to each other + a frame (Thanks to Yedidyha Vardi)

A simple plastice chair and the "Gas" control was changed to 2 "Hand Brakes" of a toyota RAV jeep

so you control the accelerataion of each engine by pulling the Hand Brake - like a stick.

11/2/05 I am now working on the brakes - 2 seperate rear braking levers - operated by foot (some new pics soon)

23-2-05 - Day 15

Took a day off to work on the project - 14 hours with 20min lunch brake : )
On the weekend I will be in The Arava events
See you there

4-3-05�- Day 16

�Big day for the MotoTank
Rebuilt and Finished the cooling system on the left bike (thanks to Chilik for the tip)
So the engine can now run for more than few seconds.
Hmmmm.... why not take it for a ride outside?!
Well, there is only�one engine working, the�brakes are not fully ready, the steering is not set ...
What the Heck !!!�� Took My first ride on it -
F#&^ing amazing
Watch the video - (LOW RES from my Nokia cell) - make sure your video screen is SMALL
�
Lot's of adrenaline �- Left hand on gas (in the back), Left leg on rear left brake (front) right hand on steering (far front)
Allmost crashed when the chair dropped back in mid ride (was not connected at all....)
Conclusions:
1.Must have VERY GOOD Brakes
2. Goes fast with one engine - will go VERY (too?!) fast with 2.
3. Must have (also?) a good steering system
4. Should have Roll Over arch - (go see Million dollar baby and you'll get it...)
Now back to our day jobs...
Happy week

12-3-05� - Day 17 - Cooling System+ 2nd Brake

* The 2nd rear brake (used the front brakes cable (longer)) - it was cut off during test drive due to a welding problem

�

I was riding with 2 engines (one brake and no steering)� - it worked for 3 sec. and then slamed into a wall

�- lot;s of reasons... (Unfortuntally the crash is not on video)

1.The Brakes are too soft, too weak... this will be a problem. bikes are designed to use front brake as the main braking system (MotoTank don't have a front brake)

I wanted to do that ever since�I was 8 - it is so much FUN to "control" something like that - in seconds you feel you're in SPACE� �- You should try it on your company car!

�then Welded 2 Bases for the Gas handles (Mitzaarot ) onto the wheel and mounted the gas handles on them.

In the future - I need to add some buttons onto the edges of the wheel - to shot some lasers or something - it just asks for it! (if you have cool ideas - send them over)

�I also need to get rid of the FIAT logo on the wheel... it looks out of place

To all of you that worry - the wheel only goes 180 degrees (90 to each side) it is direct steering.

26-3-05 - Finished New steering

Finished the "Car" type steering (was the hardest part) - the angles are bad and should be redesigned - because there is an angle on the front wheel (not 90 deg. to the road) - it goes up & down while turning which requires too much force on the steering wheel - makes it very hard to turn.

It's also very aggressive on your body (Back Pain!)� - considering to change the name to��"The Bone Machine" (and if we're into Pixies - how about this one - "Break My Body")
