Tagada is my favorit amusement ride.
I've rebuilt it several times.
This is the latest version. It has got 2 small pneumatic cylinders,
9V motor and a stepless speed controller.

Here's the first version of Tagada. The year was about 1985.
Notice the grey lever in the rear of the trailer.
You could make the car jump by pumping it.

Coffee break. Building up is a hard work.

The second or third version of Tagada.
Notice the chrome wheels. That is not paint.
I sent 20 wheels to Denmark for chromeplating
and got 19 back (1 was ruined during the process).

Still another version. That background is now in Tornado.
