Two more people enter the scene - Karin and Bernd Schütt. They made the mistake of visiting us when I was not yet finished with the hut and had to help on a Friday evening after we finished the pancake house. The task was to put together the mount.

First attempt. I thought that the R.A. axis (the axis compensating for the Earths rotation) assembly is troo heavy to be lifted by two people. Here it is shown with the attempt to attach it with llifting cords to a pully.

Using the pully, we get the R.A. axis assembly up to the height of the mount. Karin Schütt is pulling the pully, Bernd is holding up the axis.

.Here it can be clearly seen that the pully does not lift the R.A. axis assembly high enough.

We put the R.A. axis assembly back to the ground. Should we mount the crane higher? I try that here. However, the crane does not fit there! Maybe we should just lift up the R.A. assembly by hand.

Much better! Detlef holds the mount with the lifting cords, while the other guys try to get it into the bearings.

Here you can see how Karin guides the axis into the bearing. The axis has a threaded hole in the end, which helps in this exercise.

Hooray, we made it! Not Bernd's thumb-up - detached behind the red part of the ladder.

The second item - the declination axis with the telescope mounting plate. This is not a go-to mount, but an old-fashioned with a clamp. The clamp uses a spring for preloading. Unfortunately the spring pushes the clamp in undesired directions. After a first unsucessful attempt to get it into the bearings we fix the clamp with duct tape.

As expected, the duct tape did the trick - we get the declination axis in just right.

Karin screwing the screw to keep the declination axis in place.

The kids discovered the telescope control room - and use it to play spaceship. When I took the picture I heard statements like "We are approaching the planet, captain!", or "There're Klingons on the starboard bow!" (Julius - to the right - seems to see them.)
