F. E. Baker Ltd was a British motorcycle engine and cyclecar engine manufacturer based in the Precision Works, Moorsom Street, Birmingham, England. Founded in 1906 by Frank Edward Baker, the company produced motorcycle engines under the Precision trademark until 1919. Precision engines were used by a wide range of motorcycle manufacturers in the United Kingdom and in other parts of the Commonwealth and were also used in cyclecars. Many manufacturers used the 'Precision' trademark as part of their model names, and in 1912 there was a 'Precision' motorcycle sold in Australia, but it is unclear if this was manufactured by F.E. Baker or just permitted use of the trademark by a motorcycle manufacturer.

History

Frank Baker's engine production business grew at a fast rate, and in 1911 they added an 'excellently equipped fitting shop at the works of Messrs Webley and Scott' and by the 1911 Olympia Motorcycle Show in London there were 96 motorcycles with Baker's Precision engines. ^[1]

Tom Biggs was appointed as chief designer in 1913. ^[2] Frank Baker stopped motorcycle & engine production during the First World War. ^[3] After the war they announced their own motorcycle with 350cc Precision 2-stroke engine designed by Tom Biggs. This had front and rear suspension, unit construction, and a pressed steel petrol tank that formed part of the frame. ^[4] To inject capital into the company in 1919 the company came to a financial arrangement with William Beardmore and Company, a Scottish engineering and shipbuilding company based in Glasgow, and became Beardmore Precision Motorcycles. ^[3]

Motorcycle engines

F.E. Baker sold engines to motorcycle manufacturers and to dealers under the Precision name, and for some of the larger customers they had their own name cast into the timing cover and the word Precision absent from the crankcase casting. An article in 1914 says that the Peerless Precision V-twin made solely for export was now to be made available in the home market 'under certain circumstances'. ^[5] Differences from the UK engines included round cylinder fins instead of square and an external flywheel. There was a thriving export market for Precision engines, especially in Australia, where companies like Lewis of Adelaide used the Precision engines. Engines were distributed through sole agents as follows :

A.G. Healing of Melbourne for Australia

Victor S. Welsford of Durban for South Africa, Rhodesia and Portuguese East Africa

J.B. Clarkson Ltd of Wellington for New Zealand is added to adverts from c1913

Whether F.E. Baker manufactured a complete motorcycle before WW1 is unclear, even though a 1912 Precision motorcycle is featured on an Australian postage stamp issued in 2018. It seems more likely the motorcycle was built by another manufacturer using a Precision engine and allowed to use the Precision name. Many Precision engined motorcycles used 'Precision' as part of the model name, hence Ivy-Precision, Grandex-Precision, etc. The 350cc 2-stroke announced in 1919, though, was a complete Precision motorcycle.

A remarkably wide range of engines was developed over just a few years - this list is mainly taken from the home market motorcycle engine catalogue circa 1913 (except where otherwise indicated) so does not include variants specific to the overseas market, or the engines adapted for cyclecar use which had modifications like alternative magneto locations.

The "Green" engine was unusual in that it was water cooled but with heat exchangers mounted directly on either side of the cylinder. It was used by Ernest Smith and Woodhouse, who were motorcycle manufacturers (1912-1915), in their Regal-Green motorcycle in 1914. They had used other Baker 'Precision' engines in their previous motorcycles which they marketed as Regal-Precision.

Another unusual engine project was the development during 1912 of the engine invented by Dr Archibald Low in 1911. The engine was titled the Forced Induction Engine, but it used normal atmospheric induction but high pressure fuel admitted directly into the cylinder at peak compression, so in modern parlance would be a petrol direct injection engine. The engine was 104mm bore by 78mm stroke producing 15 bhp at 3,300rpm. ^[7] It appears this engine did not make it into production, but it embodied some principles that have parallels in diesel engine and petrol direct injection engines of the future. Details of the engine can be found in US Patent 1124157 of 1913. ^[8]

The 170cc engine had the unusual characteristic of horizontal overhead valves located at the rear of the cylinder, as well as unit-construction (see images). The valves were changed the next year to normal side-valves but remained across the rear of the engine, so this was an unusual engine. Engine capacity was increased to 199cc at the same time.

The 225cc Precision 2-stroke engine that appears against 3 different manufacturers in the November 1914 buyers guide (see info below) also appears in the 1915 Buyers Guide in the model by Grandex and in a short article on 1916 Torpedo motorcycles in November 1915, ^[9] suggesting this engine did enter into production, though production may have been restricted due to the war effort. Even before war orders instructed companies to turn to making parts solely for the war effort, there were serious problems with loss of staff who volunteered for war service.

Motorcycles that used Precision engines

Before WW1 there was a booming business with mainly cycle makers adding motorcycles to their production. This was facilitated by companies that provided engines, forks, seats, gearboxes, magnetos, lights and belt drives, allowing the frame maker to assemble his motorcycle. One of the main engine suppliers was JA Prestwich Industries (known as JAP), and to some extent F.E. Baker were targeting their market. The Precision V-twin introduced at the Olympia show in November 1911, followed the same 50 degree V angle as the existing JAP V-twin. While some motorcycle and cyclecar manufacturers stuck to a single supplier, others swapped between engine suppliers, and some allowed customers to decide which engine they wanted fitting. In November each year the Motor Cycle show was held at Olympia, and a Buyers Guide published which in most cases revealed the engine supplier used by the companies, enabling an idea of the large number of motorcycles using Precision engines in the UK. ^[10]
