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.

There are a number of smaller components that make up the RA braking system. All of which were missing from my project. One of these is the link that gives the rear brake shoe a parallel motion as it engages the brake ring. One end is anchored on an eccentric to allow adjustment of the angle of the shoe. The first batch of eccentric bolts for the rear was based on the example seen on the Bob Thomas RA outfit. This turned out to be wrong as that was the 'early style' and my RA, if it ever had brakes, would have been the 'late style'. Oops!


Early style rear link eccentric pins. Eccentric split collet on right for turning and threading the stud offset from the pin journal.


Early style rear link eccentric pin and link on the left. Later style on the right.

The rear link is a made from folded bit of thick sheet steel. The one hole is quite close to the bend, so to avoid distortion – and also to get the holes aligned – drilling and reaming is done afterward. In the next picture, an original link can be seen on the right adjacent to sequential machining operations.


Sequential operations.

I have just applied to join the London Douglas club - is this who manages the stock you refer to? I have bought a 1951 "80 plus" and starting to look for where I can get replacement oil filters.

Thanks

Hi Simon,

My apologies for the delay in replying.
A list of all spares held by the club for post-war machines can be found on the clubs website -https://douglasmcc.co.uk/post-war-douglas-spares/
My email address is listed there and I'm very happy to receive enquiries from members.
All the best,
David

Auction house is learning all about Duggies !

The gal that does the website emailed all the Douglas bidders a couple of days ago that the descriptions were inaccurate.
Since then, the bidding has intensified !

I went to view these bikes yesterday and told him what models they were. We found some of the frame and engine numbers to identify the year. The TS frame number was under a lot of paint and filler so could not be seen.

Quote from: EW-RonPretty swift action for an auction house, I'd venture.
Yes, that is pretty responsive. Whenever I write to auction houses requesting permission to use their photos, they never reply.
Anyway, here's a couple of snips and links using their updated headings so we don't have to scroll to the top of this topic.
