If you're thinking of phoning Tony - too late. It's gone!

I've already acquired it for the Club's Technical Committee.

That is good news Graham. :)

I would strongly disagree if that means the drawings, as a piece of HRD history and useful technical information, are lost from view to the world's Vincent Owners.

For my part I have a pair of as-cast cam-boxes and would dearly love to see the drawings so that I can machine them properly for my own A project.

Is this the thin end of the wedge? Are we to assume all Bob Stafford's 'A' drawings and sketches are going to be removed from him and put in the secret vault too? :mad:

Hi Peter

You're more than welcome to see the drawing - I've not reason to see why it should be a secret!

Only the drawings that the Technical Committee produce are subject to the Drawings Protocol.

I must say however, there seems to be a theory that Arthur Farrow as Drawings Manager has an enormous archive of non-Technical Committee drawings, and this is just simply not true.

One evening, he took me through exactly what the club had been gifted over the years, and there just wasn't much there of any significance.

I'm not sure if he has a list of what we have, but I'm sure he'll tell you if you ask him.

Peter / Graham,

Maybe I could make a suggestion, and a copy of this drawing be sent to Bob Stafford as he is the focus point for people getting drawings / sketches and info on series A. He certainly has been very helpful in our A Comet rebuild and is willing to share any information.

Cheers,
Simon.

I was never in any doubt that you (Graham) had the best of intentions to secure the drawing on behalf of the VOC to prevent it falling back into private hands never to be seen for another 70 years. This has happened to too much of the A stuff including the elusive A Twin crankcase drawing. But I am also aware the the Tech Committee are busy making drawings of A parts with an eventual aim of providing A spares through the VOCSC; hence my concern that this original drawing (if it is) might be spirited away for that purpose.

If that is not the case, then I am a happy man and withdraw my comment above. Moreover, I fully support Simon's view that Bob Stafford should be provided with copies for the benefit of all. :)

OK, let's see what it's like first.

I'll report back when it arrives (in a few days the guy said).

Regards

I had my hands on the drawing in question, and it turns out it's a camshaft cover for a Vincent Speedway Engine.

I've shown it to Arthur Farrow, Derek Sayer and John Sayer, and they think it's the first time they've seen the drawing, so a good result.

Derek Sayer currently has the drawing, but as and when I get it back, is there anyone who would like to see it published here on the forum?

The drawing almost certainly came from the estate of the late Frank Shillito of Newmiller Dam, Wakefield, who died earlier this year. He used the drawing to machine a casting which he had aquired along with the drawing when he built a Speedway engine for me in the early 1970's He found the drawing had some crucial errors!

Sure Graham, it is clearly of little use to the majority of people, but nevertheless, its still a neat piece of Vincent history which would be nice to see!

The mention of Frank Shillito by John Emmanuel takes me back at least 45 years to when I first met Frank. Frank was a CHARACTER and a very clever engineer. Lacking a lathe large enough to turn a Vincent cylinder head he used to weld the damaged exhaust port threads up and then clamp the head on the tool post and fit the thread cutting tool into a 4 jaw chuck. That way he could re-cut the thread. I remember going over there one day and he had just finished making a new clutch drum with lightening holes for Jim Smith of Pegsdon. The drum was made of vibrac and such is the small world of Vincents that when I bought the ex Cecil Mills bike, what should be in it but the same or a similar clutch drum.

For those who fancy their ability to set up an engine properly the following is a test which I have seen Frank perform many times on Rapides which he had set up. He used to get the engine warm, put the bike into first gear and then walk along side the bike with the clutch fully engaged and the engine ticking over. As Frank was about 5' 2" tall and round rather than whippet shaped this was a real test of both the clutch and the flexibility of the engine. A very competent man!

Norman,
You forgot to say "Don't Try This At Home" Some Vins have High first gears and big carbs.
I can just see heaps of Vins and there owners all over the world !!

Just a bit of fun. Bill.

Aha Bill!

Note I wrote Rapide, that is original small carbed, low compressioned and low first gear. Frank's test was a really good test of engine flexibility and the clutch. Like you I have ridden more tuned machines for years in that youthful lust for speed that many of us had. When I rode a standard engined Rap a few years ago, the first time for many years, I was really impressed by just how much more friendly it was in traffic. In the meantime I agree that those with tweaked engines should picture themselves either pinned to the floor under a revving machine or flying cartoon like from the handlebars. That should stop them trying this test out for themselves.:rolleyes::rolleyes:
