Other dimensions will be gathered from the various diagrams of details.
The reader will, of course, suit his own fancy in following these
dimensions, or in working to them on a reduced scale, or in modifying
details where he considers he can effect his object in a simpler manner.
The diagrams are sufficiently explicit to render it unnecessary to describe
the making of the engine from start to finish, so remarks will be limited
to those points which require most careful construction and adjustment.
