Why am I trying to use a helicopter to cross the street?
Yes, my idea is workable but it's too complicated.
I could just use the already existing G-3 tank. Few modifications would be needed.
We only need to modify the reels inside the tank so that they allow the solutions to circulate around the film.
As they are, the convolutions of film lay together as it rolls up. Not enough solution is in contact with the film.
This is the main problem with the G-3 tanks.
However, we've got something working for us: Short film. Only six feet.
Can we make a reel that fits the existing tank which keeps the film apart? Possibly.
The tank already has an exposure portal. We only need glass filters to color the light properly.
1) Put film in tank, base side out.
2) Remove rem-jet. Develop. Wash. No counting needed. Just crank the cranks.
3) Place the filter. Open the portal. Crank to expose.
4) Redevelop #1.
5) In the dark, flip the reels over, putting the emulsion side toward the portal.
6) Repeat steps 3 & 4.
7) Chemically fog, redevelop and complete the rest of the process.
It's a little more work, a little more thinking and not as automatic but I don't think this is beyond the ken of anybody here who already knows how to develop reversal film processes. It just takes more steps.
It uses existing equipment with only a few modifications.
We only have to work out the modifications to the reels.
Stephen already knows the chemistry.
I think this could work.
What if we wound a piece of mesh or similar material up on the reels as the film goes on?
No modification needed. The mesh would hold the convolutions of film apart enough to allow solutions to circulate.
What kind of mesh or "spacer" material could we use?
