Title: 1921 Sunbeam standard
Post by: Anji Mehra on April 26, 2016, 07:49:23 AM
Hi,
My Sunbeam tank seems to have been modified in the past. Can someone help with either a photo or drawing of the tank so that I can restore it back to original
Thanks

Hi Anji
I have a few photos of models around that era but not specifically the 1921. The photos below are from a 1923 and 1926 I will also post photos of a 1917 model.

Hi Anji,

I have sent you a sketch of a Model 7 tank. It may not be exactly the same as yours, but it will give a very good idea of the lining layout.

The magneto is likely to be an EIC, although an ML would work just as well. The carburetter could be either a B&B or an AMAC type 15 HYDM or HYSP. The choke diameter is probably 1" although you could use a 15/16"

I hope that helps!

Paul

There is quite a nice looking 1922 model 7 on UK Ebay at the moment looks quite good as far as originality goes and worth borrowing the pictures  ;)

Thanks Paul. Great help. There is nil info here in India about Sunbeams. I have restoration manuals of almost everything under the sun, but cant find any on this bike. By the way, I cant access the sketch you sent. Could you please resend.
Attaching a few photos of the tank. Does it look right to you ? Also attaching a photo of My Flash we restored 6 years back. Take her often to Goa ( 550 kms ea way )

Hi Andy
Very gracious of you to offer help in my restoration. Much obliged.
Your bike is a beauty. How does she run & are you able to ride often ?
I will be in touch to bother you once I dismantle everthing.
Yhanks again for the offer

Hi

Another query : Is it permissable to use a BTH KA 1 mag on the 1921 Sunbeam. Iam unable to locate either a MIC or a ML
Thanks
Anji

if it fits the platform and goes in the right direction,  probably yes
Title: Re: 1921 Sunbeam standard
Post by: phutton on May 03, 2016, 01:15:45 PM
You will also need to check the spindle height of the mag above the platform. As standard, mags were either 45mm or 35mm. A 35mm type can always be fitted with a spacer plate between the mag and the platform.

Hi
Is it OK if I use stove enamel black paint. There's a guy here who specialises in stove enamelling.
Title: Re: 1921 Sunbeam standard
Post by: iansoady on May 08, 2016, 02:11:29 PM
Stove enamel would have been the original finish for frame, cycle parts etc but you need to be careful as some modern re-enamellers won't be familiar with older bike parts. It's increasingly difficult to get it don in the UK.

I would echo what Ian says - a lot of parts on a flat tank Sunbeam are soldered, so high temperature stoveing will see the tank, rear chaincase etc, fall apart!

Hi
Soft solder will melt at 180-190 deg C.
