I presented the plywood velomobile to on the Summerlab in Nantes.
Watch the video. We tested the machine. The seat, the front suspension, the soft top and the chain guidance were failed or considered inadequate and than repaired and improved. Thank you guys!
We have thought about how the plywood sheets can be attached. Below you see a sample.
 |
| provisionally attached with staples... |
 |
| glued with wood construction glue (foaming PU) |
 |
| will we ever get these staples out again? |
To get experience we tried to make a hard top too.
The chain is guided by four toothed chain wheels to reduce the losses up to the max. But it would easily derail from the rear sprocket because it could not be tensioned properly.
 |
| Jacques and ? (sorry I forgot your name) are adapting the wheel mount so the chain can be tensioned properly |
Joris wanted to make a one wheeled trailer (remorque). I showed him my plywood design. Building a simple trailer was a fine way to learn (developing the sheet, bending the alu tube... )
 |
| Joris has made a mock-up to evaluate the shape and generate the development of the sheet |
 |
| unwrapping the sheet |
The edge at the top of the trailer will be reinforced with a tube. Bending it is not so easy. Because we did noty compensate for the elastic relaxation the tube did not get its definitive form directly...
 |
| bending aluminium tube Dxt 18x1 |
 |
| for the last turn we fix at a new position the tube so we can release the first par |
 |
| oops ! We should have filled it with sand... |
But not only details were studied. Scale models and a 1:1 mock-up was made too:
On the
wiki you will find some more !
The summerlab was a very pleasant gathering of interesting people and thoughts. Although not presented at the summerlab and already written in 2004 to me the most intriguing was the philosophy on cyborgs of
Natasha Roussel.
