Support for the repair of our roof

The south side of the tach roof of our barn (=our workshop) is in bad condition. Out of the blue, two very special people popped up offering help with the repair: Hans de Haas and his son Arjan. Hans has a special practical knowledge of basic handicraft work, such as axing timber out of logs and the construction of roofs in days long past. He did action-research on such technologies as used in the stone age and in medieval periods.

Arjan de Haas has a similar expertise and is involved in a development project in Senegal. One of the technologies he introduced in this project was -to my big surprise- the rope pump! There seems to be plenty of overlapping interests in both our field of work and expertise. I am looking forward to the chance to work together on the roof this week and on other projects later on.
As a contribution to start with, Hans en Arjan donated bundles of reed they loaded on my trailer as the picture shows.
