"Sometimes people thought we were both crazy," jokes Joop Nijland as he talks about his experiences. Together with HORN technician Roger Kasper, Nijland has spent the last 30 years devising tool solutions that have left many people shaking their heads. His expertise in tricky tool solutions earned him the nickname "the crazy Dutchman". One of these solutions can be seen in the milling of a round thread used in shipbuilding at Kooiman Marine Group, near Rotterdam. Milling the thread having a diameter of 400 mm (15.748") and a pitch of 40 mm (1.574") increased production quality and led to significant time savings.
