Mounting a rear MTB rack on a road bike

Today I finally got my road bike a rear rack.

The lightest rack I had was from an old Specialized mountain bike.
Since my frame has no mounts for the rack, I had to get creative:

First I got a steel plate, like every hardwarestore has:

I cut out the following parts. Drilled holes, bent and painted them.

The bigger plate is screwed to the rack.

Now I placed the two smaller plates between the quick release and the frame. I used the brake screw to connect the long bended plate to the frame.

 So thats my bike. Forgive me all the lights and reflectors, but this is the setup for a 24 hour ride.
