Doorstepclimber - The problem and a solution
The problem with the cast not fitting the tire turned out to be something we had overlooked. After examining 6 tires we concluded that the tires themselves where made up out of 2 half tires glued together.
This results in the profile not being aligned the same way on different tires, and therefore we aren't able to make a "one size fits all" mall.
We had to shift focus on a fixed profile, so we decided to have a look at the wheel itself. Maybe it would be possible to modify the rim. So we went to the basement and removed the wheel of my spare wheelchair.
Now we are looking into ways of making a rim ourselves. We are considering laser-printing multiple layers of corian, cutting out of metal with a plasma cutter, or casting aluminium.
