EW petrol and oil tank caps
« on: 12 Mar 2020 at 03:51 »
So, the EW 350 project has stalled over the petrol and oil tank caps.
I've never seen what these look like, and have been thus far unsuccessful in tracking any down.

I've read the advice about buying Austin 7 ones, and "modifying them".
But modifying them to what  ??
My tank has 2 little lugs per fitting, so what does the underside of the cap look like ??
This is what I have at present, but clearly it lacks/needs something.



This cap also is chromed, and it should be nickel ??
Do other duggies (douglassi ?) use the same cap ?

Any pointers greatly appreciated, pics would be marvellous...

Hi
Regarding  Austin 7 oil filler caps.
 If you go to theaustin7workshop.com look under pares part number Eoo83 (note their are two different caps the one that fits is marked coil) there are pictures.
I have fit two of these to my EW the petrol cap requires an air hole drilling.
The butterfly underneath does not extend far enough out to catch on the pins. I removed the old pins which were rivited to the tube made new brass pins tapped m3 and secured them with m3 c.s brass screws. I then drilled and tapped the butterflys to take the chains,where to fix the other end of the chain as yet to be resolved, fixing to the filler tube it catchs the cap.
The caps I purchased are brass from another supplier a7.coukspares.
Hope this helps
Keith

Thanks for that Keith.

I'm a shade disappointed that the club hasn't been involved here, since if the Austin 7 Club can have new caps made,
it wouldn't have been a big jump to have some made which fitted Douglas tanks.  ??

Along with tyres that are no longer made in the size the EW used, this makes the once most popular selling bike on the planet (!!)
less than simple to refurbish...
Cheers !

Re rims and tyres not true...
If searched, lots of stuff on this on the forum and the most popular way with tyres being unavailable, is to replace the rims with wired on type rims of same size ie  Bantam or similar...all easily available and not expensive.
This then gives you access to a wide range of off-the -shelf classic bike tyres . My previous B29 ( a go faster EW and in the picture gallery) had these and looked very nice..
If just for show, then I have seen a bike fitted with mountain bike cycle tyres, which would fit the old rims.

I have thought about that.
But its not really show quality (yet ?), and it means it could never be ridden seriously.

I've also thought about the bantam rims, but by the time its rims and spokes and rim bands and tubes and tyres and lacing,
its barely an 'inexpensive' option, especially when the present wheels are in good condition and perfectly serviceable
- if only the required size of tyres weren't unobtainable !

I've also thought about 2 & 1/4" clincher tyres - but these are reportedly quite hard and thus give a rough ride,
and also look skinny when the EW was touted as the new "modern" look.

We diverge a shade though.
I'll think on it.
P.S. I wonder what happened to the moulds for the correct sized tyres ??

Long gone now I would think, it wasn't a common size even back in the day

Yes they were probably melted down to make battleships !
And then into Morris Minors...

They were a common enough size at one stage though, the EW Douglas used them,
and they were the best selling model of motorcycle on the planet in 1926 and 1927.
Oh what a fickle world we live in !!?

Meanwhile I'm still chewing over what to do about tyres and rims.
Wonder if bantam wheels would just bolt straight in, sort of.
Non-beaded edge tyres and more conventional brakes and all...

Hi Ron,

Use the "search" box in the top right - there has been a great deal of discourse over EW rims over the years. 26x3 BE was an option for the EW, and both rims and tyres are available and practical.

Cheers

Thanks Leon. I have perused such searches at some length, and am still quite undecided which way to jump !
Re-rimming perfectly good serviceable wheels goes somewhat against the grain, so just going to bantam spec beckons a little...

The latest LDMCC mag mentions the tyre issue several times...it also mentions that Douglas brakes were noted “as not particularly good”...a classic understatement... My B29 brakes were awful despite lots of fettling and as Doug said several years ago...Douglas brakes either work or they don’t...... The article said many converted to BSA or Norton brakes.
My runs were in built up areas so for survival , I used Triumph internals from drums of the same internal dia on the rear and the difference was to say the least astonishing. If you end up stripping your wheels, then worth considering converting the brakes or at least the rear to a sls at the same time.
