Ideas or help for model team-like construction

[Carsten Svendsen]

I'm not familiar with a whole lot of studded bricks or their building techniques at all, so help and pointers would be appreciated.

First off, everything shall be made with studded bricks to get the right curvature. The studless liftarm pictured above is just an illustration.

Secondly, I need the inner part and the outer part, which means the 15L liftarm pictured above is the inner part, and the frame around it is the outer part. (It's an enclosure that opens)

I only need ½ a circle. Orientation of the studs on the bricks doesn't matter as I will have to adjust it anyway.

The center point is the first hole of the 15L liftarm and the opposite end of the liftarm is the end of the opening door. 

Is this possible?
