Michael (Mick) Groome

Mick has a long history in the motor trade as an engineer and joined us in the summer (2017). Mick has brought an eye for detail and the ability to simplify processes and mechanical systems. Since Mick joined the Dofygate he has become an invaluable part of our continuous quest for improvement. Mick lives just 3 miles away from the office and assembly workshop and is always on hand when needed. Apart from Dofygate Mick’s main interest lies in shooting both game and clay pigeon and is an important member of the local clay pigeon club.

Robert (Skip) Donaldson

Skip is based in Erpingham and his own business RKD Engineering. Prior to becoming heavily involved with the Dofygate project Skip has been involved in building telescope mounting and control systems. Precision one off engineering with turning and milling machines that can produce accurate parts to drawings supplied. Despite being Australian Skip is not particularly interested in Rugby which rather spoils it when we beat them. Skip is involved with the North Norfolk Railway based at Sheringham and is a qualified steam engine driver. His ability to produce accurate reverse engineered parts for this historic machinery is a real benefit to a railway run by volunteers.
