Hi everyone from South Africa!

I am in the process of making a f15 8" Dall Kirkham. My primary is near figured and secodary complete. Onto mechanincs now I guess... I would like to focus the system by moving the primary on the cental tube. Any comments? Does anyone know of a nice picture or diagrams on the WWW I can get ideas from? One of my major concerns is stability whilst focusing. At the moment I am just fooling around with various ideas of how to move the primary on the central tube. Any comments, critisism or ideas are gladly welcomed.

Thanks, Andre
