I am pretty desperate for a rear cylinder for my veteran Douglas 1917 2 3/4hp "W" model.   I there is anyone who may have one of these that can be re-sleeved or know where I may find one I would be very pleased for the help.  I have a number of engine parts that I can exchange such as matching crankcases, conrods, crankshaft, flywheel etc. Any help appreciated.

Does anyone have the specifications for the oil inlet valve spring for early 2 3/4 engines - Part number 424.   I have tried to order one from the club spares but apparently Jeff Swan is indisposed at the moment.

Early Douglas (2 3/4hp) Fork Spindle Sets - Update

Hi All,
I have finally got round to writing the CNC programs for early Douglas 2 3/4hp Fork Spindle kits - the type of fork fitted I believe between approx. 1912-19.
Spindles are manufactured from tough stainless 316 and original Douglas fork spindles pulled from an original set of forks were used as the template.  The set is four spindles and includes the original type castellated nuts (also in stainless), as well as washers and split pins.

They have been made in a slight oversize, to take into account original blade/yoke wear (and not having enough meat on them to safely rebush methinks), but detail information about them can be found in the item listing on our online catalog.

See link to these spindle sets on the (small) Douglas section of our SOHC Norton online parts catalog:

Hi Everyone . . . it has been a while since I have been in - hope everyone good.

Just as an update - as I sold out of these fork spindle sets quite some time ago.  The last year has been quite difficult (machinery issues - now resolved touchwood, and some family illness etc). . . . so I am well behind on numerous re-stocks (Norton and Douglas).
However, thinking ahead . . . I was intending to make a new batch of these 2 3/4hp early type fork spindle sets again in the next 6 months.
With that in mind, trying to ascertain numbers - if you are interested in a set, then you can email me on paul.norman@racingvincent.co.uk.

If I dont reply within a week or two, my apologies, but just try again - not enough hrs in day at the moment. Best
