Hi guys,
I'm glad you like my design! It's nice to get that kind of reply from someone who "can swim in waters of landsailing".
Now I'm a litle bit further with the design. I think all base stuff is done, so I can start work on details.
First of the detailing work was/is/will be the stearing and breaking system.
Breakes are aleready done - I've decided to use the disk breakes (from motobike) mounted on rear wheels, together with two main breaking cylinders (also from motor bike). Breake can by apply to each wheel separatly.
Stearing is in the design phase. It was quite hard to figure out how to do it, but I think I found (together with my colegue on coffe break) how to do it. The solution is the use of steel rope for driving the front axle fork.
The main probelm was the different angles of rotation of the axle fork and stearing pedals. Now on boths sides (pedals and axle fork) will be mouting on the frame for a bowdens and then the rope will go trough a set of leading wheels. This part is under construction, so there are only place holders for the real parts.
Just for better understanding - The pedal is constructed in such way that when you press it with heels you can move it in vertical axe and the press by tip-toe will activate the break.
gibberjoe - this is free to personal use only

otherwise I will want some percentage
