you must take care for positiv or negativ earth of your dynamo.
You can change it on the dynamo.

I add a photo of the voltage control (neg. earth) of my MK1, I think it is a nice place to fix it in between the tank bracket.

What is the diameter of the brake rim and how wide is it? For my 2 3/4 HP.
Thanks Daren, learnt a lot about Dougys very quickly! Judging by the support bars this B29 had foot plates, i see some had foot rubbers?

On my 350cc H3 Douglas is one of the clips missing. It is to hold the (half round) rubber.

Has anyone an idea of a source or a reproduction?

Hallo Everybody,

Is there anyone who could help me whit a handlebar for my douglas 1912.

Kind regards,
Peter Kuiper

Thanks Doug. The taper on my worm is so slight that I suspect it is designed as a press-on interference fit, so perhaps the whole thing is a replacement part - machine off your old worm, press this one on.

At least one of the pumps is Douglas! Thanks everyone.



It is worm drive. The worm is integral with the timing idler gear.

Yep, I guess it could be an Aussie-made version of the DT pump - we had DT's running until after WW2 and a history of making knock-off spare parts. But the pump in your photo is not worm drive? Or is it just an optical illusion.
