Thanks Bob for a good idia of Doomwheels!
I've got my new weheels from local bicycle store this afternoon. Bit of shopping, bit of drilling and a new Doomwheels are done by 7pm.
It's just a temporary model! I looking forward to change the rails & inserts on titanium or carbonfiber.
Ofcourse! Freaking wind have died by the time I finished the Doomwheels . But I tryed it without kite(I got FlySurfer- Psycho 2 - 13m) it feels like downhil ski.
If I'll have someone around I'll send some action pix!

Excellent job! don't worry too much about the weight of the rails, just that they are as strong as possible. It looks like you have soft boots... let us know if you have trouble with the ankles being too flexible. Yes, post action pics. We have plenty of skate pics on the PKF but not so many of them in use. Good luck and have fun!
