Developing advice

Hi all.

I've been playing about with Super 8 for a while, and done some 16mm
developing too.

I've got an old developing tank where you crank the handles and the film
goes from one spool to another inside, and you can pour in the chemicals and
tip them out.

I've got a feeling I got it from Lees cameras in London a few years ago, but
I can't be certain. I know it was expensive though.

I've lost the instructions, but can anyone let me know an advised method to
develop films with this?


I seem to remember something about giving the film 50% more time on each
stage because of the time taken to wind the film back and forth through the
chemicals, but does anyone know?


Any cheap sources of film too?
