Hi relaxibus

That was a little tricky one because the lines were under x degree but this is how:
1) draw a line under x degree
2) draw a circle ore whatever perpendicular with the line and extrude it
3) draw a line to duplicate around
4) use snap "workplane on"
5) put the workplane perpendicular to this line
6) now you can use the polar duplicate by this line

that's it, good luck
