Square four Scott engine Abbotsholme presentation

[Roger Moss]

Bob Collett, ex Vauxhall engine designer, designer and maker of a sleeve valve engine for his own bike, currently designing a compact diesel, has a new project. This is a sqare four “phased transfer” two stroke based on the Scott engine. It is an ingenious and unique project to which I am giving what help I am able with the manufacture.
Bob has agreed to give a presentation at the Abbotsholme weekend on Sunday morning March 30th. It will be given in honour of Alfred Scott and to demonstrate that after 100 years, his spirit of original engineering thought, still burns brightly. This presentation should be a treat for owners with a love of engineering and Bob will welcome with open arms anyone who wishes to be involved in the project

Roger, so glad to know that Rob Collet is alive and well and still interested in unorthodox engines, you forgot to mention his supercharged two stroke four stroke Triumph twin that he built a while ago. Rob Collet was also a serious vintage motor cycle racer from the fifties through to the seventies,a Scott owner too, he bought a 47 Flyer from my brother to travel to Luton where he worked, along with this Flyer was the bones of a vintage Scott which probably formed the basis of the Scott Norton which Rob raced so succesfully. Please give him my regards the next time you see him. Alan Noakes.

Very much looking forward to this! Ever since I saw a picture of a Morgan (or similar type) powered by a the Scott V4 engine in an old Yowl I wondered why not more people tried a multi cylinder Scott…

Abbotsholme is starting to sound better and better. Now all that is needed is just to assemble my Scott….

Cheers,
Erik

hi erik!

Concerning the Scott powerd Morgan – Which Yowl?

Thx,

Alex

[Erik]

When looking for it I could not find the image itself. But I am very sure I have once seen it and I thought it was a V4 Scott mutant. But where…

The digital Yowl archive I have is until Vol 8, No 7 but the index tells me there is an article on a Scott powered Morgan in Vol 8, No 9, Pg 20.

So if you have the old Yowls in paper you could have a look!

and there it is:

YES! that is the one! Nice job. But not a real V4 as I thought but more like two coupled twins.

But still definitly one for Top Gears Cool wall!

[ERIC BAYLISS]

Hi Erik the picture you were probably thinking of is on page 51 of book one The Scott Selection by John Underhill. a proper V four with blower.

[Erik]

Thanks Eric! Will check when I get home.

But nevertheless this also is a cool piece of work!

[BRIAN MARSHALL]

THis machine did Not have a V4 engine. It had two ordinary Scott engines mounted back-to-back, and coupled together by yards and yards of chain so that both rotated in the normal direction.

[Erik]

@ Eric: I had a look but the one in the First Scott Selection was not the one I was talking about. I remember the picture as coarse and the engine on a Morgan. So the pic from Yowl definitly is the one.

@ Brian: now you mention the “yards of chain” I also kind of remember seeing a drawing of this chain and chainwheels in this engine.

But where……

[ERIC BAYLISS]

\\\hi Erik there is another picture showing some of the chain on page150 in the third selection Eric

Hi Erik,

You will find an article about Granville Grenfell’s Scott-Morgan Special in Yowl volume 3 no. 6, August 1963, on pages 8, 9 and 10. It is accompanied by a Klemantaski photo of the front of the car under construction, and a diagram of the coupling chains and sprockets.
There is a road test in Motor Cycling in October 1936, which was reproduced in Yowl dated July, 1959.

Regards,
Carl

[Erik]

YES, that is the article I saw! Thanks!

Cheers,
Erik
