TickTock and DTD thanks for your replies. For some unknown reason I was picturing a chainwheel on the right side hub instead of a multi-speed freewheel.

I'll just call it a Senior Moment !! Or perhaps due to the excitement of having recently completed my front fork. Not very much but its nice to have something completed after nearly 18 months. I laced one rear wheel about a year ago but then life got in the way and put the brakes on my build.

Hope to complete the second rear wheel, soon, and will post pix of the completed fork very soon.
