Hi Daren,

I really wanted that 2 3/4 but with the buyers fee and shipping to Western Australia it was getting expensive.

Hi Dave.

I had a problem looking at Doug K's last post I logged in multiple times to get asked to login again

Some lovely machining there Doug. Id kill to have a cnc at my disposal, but ill have to keep hacking away at it all manually. Thankfully havent had to take on something this intricate yet.

Just a reminder the above mentioned post in Douglas Motorcycles Technical Articles is an ongoing topic with updates ever week or two.

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.

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

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 !
