Homebrew iambic key

It was time to get myself an iambic key. While my Bencher is still in Poland, I decided to make the paddle myself. It took some adjustments and more work may be needed later, but the first impression is very good - almost like Bencher...

The key has been built of materials and hardware available at home (plywood and steel) with simple tools (saw, driller, screwdriver and soldering gun). Total cost is 1 Euro in screws, nuts and washers, 2 hours of my time (time is money) and my son's bleeding finger (what are these interesting tools Dad is playing with?).
