In my computer! But I can send you the file. Please understand; it is ONLY a drawing of the blades for use in etching to cut out the thin pieces without damage likely to come from mechanical cutting methods.
I do have the mechanical driver but that was done without AutoCad (I did not even have a PC then.) I can make you a sketch in AutoCad; it is a pretty simple thing but seems to work well (I used to test it by running it on a function generator to make it rapidly open and close the shutter. For the small blades needed for a Metrogon I could reach good speeds, maybe 1/100, though that was a long time ago and my memory might be wrong.) Let me know whether you need the additional sketch and feel free to remind me about the blades (I am under stress and probably will forget! In two days all will be more relaxed and then I can do it!
