In part one of this quality DVD, Ivan Law talks to Cherry Hill about her latest engine, the Robert Blackburn 1863 Agricultural Engine. Cherry's models take many years to design and construct, the end result being a superb example of precision model engineering. This section includes video of the engine.
 
Part two is all about Mike Sayer's 1:3 scale 1923 Bentley motor car engine. Mike built this car engine from scratch and had to learn many new engineering and modelling techniques to overcome manufacturing problems.

Part three, the bonus section, is all about the Gas Turbine Builder's Association. James Hill describes a typical small gas turbine engine throughout several stages of development. Although I am never likely to build a gas turbine engine, I still found this section very interesting.
