Have you tried the new Drafts feature yet? I just lost a long message today and learned my lesson. It is a good idea to save a draft of any long post you are writing. You can then just keep writing and keep saving a draft, knowing you have a backup if there is a glitch. The draft is automatically deleted when you post the message.

General Douglas Discussion / Re: Fairy Petrol Tank
Last post by Hutch - 13 Jan 2025 at 06:26
Hi Tony,

I cannot help you with any details on the tank of the Fée (Fairy), but Doug Frost recreated one for his replica. He may have more information on some of the details which are hard to pick out in the pictures??

https://www.icenicam.org.uk/articles3/art0055.html

For other forum members, some additional information (as Suggested by EW-Ron) on  Fée/Fairy's here;

https://www.douglasmotorcycles.net/index.php?topic=6560.0

Doug Kephart's picture appears to be the clearest one of the tank I have seen, but maybe better ones exist (in the registered design archives)?

From Doug Frost's article;
"....With one very good sharp photo of the near side I was mystified for a time by the existence of two cylindrical objects fixed somehow to the frame under the saddle, on the off side.  I could only deduce that the front one, being one inch in diameter, was the oil pump, and the other. which was larger and seemed to have a cap, could be an oil reservoir.  This proved to be true as the handle on the oil tap at the bottom of the pump was just visible past the coil.

Another mystery was the three possible filler caps on the fuel tank which we had assumed held petrol in the front and oil in the back.  Eddie Turner came up with the observation that the fuel system was a surface carburetion tank, which was a system new to me, and all the odd control items on the tank, including the drain tap, turned out to fit diagrams found on the Internet."

so two caps - one for the oil and the other for the fuel and the 3rd item is an oil pump?

And,

"....Studying the photo on one occasion, I realised that there was a reflection on the tank which showed that the picture was taken outdoors and there where small trees in the background with no leaves and a bleak sky in early or late 1905, making Bedminster the likely place that the Fée was constructed and photographed. ..."

So it appears Doug had access to a very clear photograph?

Cheers

Hutch

Can't help too much, since not even sighted a Fairy in the metal.
Esp such an early one. What year is this ?

But those brochure ? pics don't seem to show much in the way of oil or petrol line(s),
or they are very indistinct
This is not a case of pics being 'tidied up' from the photoshoot is it. ?
Might make getting things accurate a little more difficult....

So are these all fillercaps, or taps-needle valves as well
Have fun, nice project.

P.S. Fairies have been well discussed here previously, it would seem.
This a cover photo even.

A 1st place award of Tudor Thompson for multiple classes at the Canford Park club speed trials. Accompanying photo is also of Tudor, but not sure it's from the same event as the award.

Quote from: cbranni on 12 Jan 2025 at 19:20 Hi there, you are in the right place to adjust the tappets and quoting from the manual

The tappet clearance with this engine should be .006 for both inlet and exhaust and at no time should the clearance be below this amount.

First insert a feeler of the correct thickness between the tappet and valve adjusting nut, then adjust the nut until it just holds this feeler in position, after which the valve spring collar should be locked against this nut and the feeler withdrawn. The adjusting nut and collar must at all times be securely locked together, otherwise the tappet adjustment will quickly vary and cause damage to the valve stems.

Hope this helps

Colin
