I.C. Engines at the "M.E." Exhihition

Loan Exhibits

There were two i.c. engines worthy of notice in this section; the first was the 30 c.c. marine power plant by Mr. R. O. Porter, of Virginia Water, and the second was the Atkinson "E.A.M." 47 c.c. cycle unit by G. Goodyear.

Trade Section

The Atkinson 47 c.c. cycle engine unit (already mentioned) was also featured, in the form of a set of castings and parts.  The consists of a four-part (sic) flat top two-stroke engine of 1½ in. bore by 1½ in. stroke, in conjunction with a chain-driven ball bearing countershaft, incorporating a plate clutch.  It is designed to fit in the frame of an ordinary cycle, driving on the back wheel by chain and sprocket gear.

A feature of special interest to i.c. engine enthusiasts was the demonstration of machining engine components on the Myford stand.  The type of engine selected for this demonstration was the "Busy Bee" 50 c.c. auttiliary engine, which is sufficiently large in the size of essential parts to present problems to the users of small lathes, but it was convincingly demonstrated that all the castings and other parts can be handled quite efficiently on the Myford ML7 lathe.  It is, perhaps, opportune to observe that the Myford Engineering Co. are not interested in the commercial exploitation of this engine, either in the complete form or in sets of castings; but the latter will be available from Messrs. Braid Bros., of Hackbridge, Surrey.  As the engine will be the subject of a complete description in later issues of THE MODEL ENGINEER, there is no need to deal with it in detail in this review.

Work shop Equipment at the "M.E." Exhibition

A visit to Messrs. Myford's stand showed at once that they have no intention of resting on their reputation.  Here was a display organised to show the ML7 and the wood-working ML8 lathe in operation.  Examples of metal work consisted in demonstrating the machining of the components of a small petrol engine for attachment to an ordinary pedal cycle.  The fact that this 50 c.c. engine, named the "Busy Bee," has been designed by Mr. E. T. Westhury, should be a sufficient guatantee of its sound construction and satisfactory performance.

Accompanying this practical demonstration was a series of excellent photographs showing the various set-ups employed for machining the parts.  These photographs, we gather, may be reproduced to illustrate an instruction manual for the guidance of Myford lathe users, thus helping the less-experienced worker to operate his lathe to the best advantage.
