Does anyone know the torque figure for the barrel nuts and head nuts for a MK series, 80+ ? Thanks

Hi alle
Thanks to everyone for your posts and for the illustrations that have been uploaded, it has enabled me to give a good lecture to my veteran friends in the local area of the island of Funen about Grady's experiences, and write a corresponding story for our magazine THE VETERAN with good pictures. A special thanks to Doug for restarting the whole debate and providing additional information about Grady.
The Google route Maps map from Halls Creek to Katherine says 913 km on current roads has put it all into perspective. Grady's story takes up 22 pages of text and may be divided into three main sections: 1. from Fremantle to Halls Creek is approx. 3000 km and takes up three pages, roughly corresponding to the distance from the top of Denmark to the south of Italy. Then 2nd from Halls Creek to Katherine, a distance of approx. 1000 km in roadless terrain, which takes up 18 pages and is equivalent to driving from the top of Denmark to Frankfurt am Main in Germany, and then third from Katherine back to Fremantle, a journey of approx. 10,000 km, which is equivalent to driving from the northernmost to the southernmost part of Africa, it takes up one page.
It says everything about the performance Grady has completed, Port Hedland to Derby or not, and how difficult Grady has experienced the 1000 km in the Northern Territory
It has been debated whether he really rode 125 miles on horseback for petrol. As I read the story, he receives a very complicated direction from Inverary which leads him astray and after two days he is back again at Inverary. The Farquahson Bros. suggest he borrow a guide, George, with two riding horses and two packhorses. They travel for 3 days until Grady runs out of petrol and then two days on horseback to Ware Hill where he gets petrol and then the two days back to the Douglas so Grady is out 7 days with horses and George has been gone for ten days before he is back in Inverary. Sounds like a true story to me.

Merry Christmas to all, it will be here before we know it.

It is a 1.445 x 26tpi thread.

Here is a post on the dimensions to machine the extractor.

It is for the EW, but the A31 uses the same thread size.

Thanks for this, and the help by email from Roy Staunton pointing to another possible extractor method - much appreciated. 
I'm also in contact with LDMCC pre war spares officer to see if any remain lurking in his stock.

I have two Plus Specials both "On the Road" that I am unable to ride due to age etc. that I am looking for a good home for.   

Aha, an extractor of entirely a different variety.

The topic of WW1 dispatch riders is a huge, but you came to the right place for info about Douglases. There is a photo guide organized by year that will give you examples of 1913 (as well as other 1912-15 models)

https://www.douglasmotorcycles.net/index.php?board=50.0

There were five models available for 1913, the models N, O, P, R, and S, The model S was the ladies model and we will assume your grandfather did not ride into the war on one of those. Otherwise there probably would have been a lot of stories handed down about that side of the family! Likewise the model N was a single speed with pedal gear, and the last year the single speed was offered at that. So unlikely one of those.

The model O was the basic 2-speed model, no clutch and fitted with foot board for 48 pounds. The model P was called the light touring and got you foot pegs and the choice of dropped or raised handlebars. Same price. The model R had a clutch and kickstart pedal, as well as valanced mudguards. That set you back 52 pounds. Unfortunately all the serial numbers (frame or engine) were sequential so no way to tell which model just from that. I was not until later on in the twenties they started using prefix letter codes on engines, frames, and transmissions to identify various models.

Quite a lot of archived military service records in the UK, so that might be another line of attack for your research.

Without having seen one, its a bigger version of this ?
Or possibly a 3 jawed one.
