Thanks Robbie, its a H16 Rex 5 Bolex. I've used this printer setup to 
successfully do straight 16mm work in the recent past. In trying out the Super 
8 gate I have not yet printed any film.

JK recommends a 50mm lens with ballpark distances of 9" from gate to gate, with 
a 1.5" tube extension and a bellows size of 3.5". This gives me no discernible 
image looking through the viewfinder.

However I can get an image in focus with a distance of 7.5" between gates but 
this leaves the lens & camera near the maximum extension possible on the rails. 
This would be fine but it doesn't quit fill the frame in the viewfinder.

I'm guessing I need further extension tubes.

What camera are you using? Is it a bolex reflex? Can you see the image through 
viewfinder? And if so, is it in focus when youve sot your previous outoffocus

Hi Frameworks, I'm at last attempting to do some Super 8 blowups to 16mm but am 
confounded at finding the right printer/lens/bellows configuration. I've
