Hi does anyone have a PDF or CAD file file for the above it must be anti clockwise as it is going on the top plate i have a setting circle already but it has both scales on clockwise and anticlock wise and this can cause some confusion at night under red light, this is the setting circle i have at present as you can see their are two scales on it, and now I realise after 12 months it can be confusing.
