Dr. David Smith (PhD in mechanical engineering, 2003 Imperial College, London); David gave invaluable assistance at the beginning of the project by searching the Imperial College libraries for papers and casebooks that Wardale needed to undertake the FDCs, and preparing preliminary designs and drawings of critical components such as the 5AT piston and valves.

David had to suspend his involvement with the project because of increased work and family commitments, however we hope that he will find time to offer further assistance in the future.

David works for Doosan Babcock (a major international company specialising in coal-fired power plants) and is also a volunteer and regular attender at the Bluebell Railway workshops.  

David lives in England.
