Duaflex II lens adjustment

[mindcircus]

Hello, I've just found a Kodak Duaflex II and I would like to take some pictures with it, just for the fun... The only problem I have is that the front element of the lens needs adjustment. It has been unscrewed so I have to find out how much I have to screw it in order to focus correct in 3.5 feet to inf. How can I find the correct position? I've tried to put my eye where the film should be, but it always seems to be out of focus.
Thanks in advance!

There are several models of the Duaflex. Some focus and some don't. If yours is the one of the ones that doesn't focus, just screw the lens all the way down. If it does, then you need to get a piece of ground glass and tape it to the film rails. Adjust the focus until it will focus as sharply as possible (on the ground glass) at infinity (50+ feet -- the moon on a clear night makes a good target). Set the focusing ring for infinity, tighten it down and you're halfway there. Now set the focus for whatever the minimum focusing distance is, loosen the ring, and fine tune it.

Edit: To take photos with it, you are going to need 620 film. Go on ebay and buy a couple of empty spools. 120 film, available in any even halfway decent camera shop, is the same size, but the spool size is different. Get some 120 film and (in a darkroom) put the 120 film on the 620 spool. Load the (now loaded with film) 620 spool into the camera, use the other (empty) 620 spool as the takeup spool, and you're ready to go.

Ok I've done that. Now I have to try it...

Thanks!
