Update 3 - DIY PVC Tube Development Timeline for Two Films
In my quest for being more efficient with my semi-stand development process for individual films, I needed a method to develop more than one film at a time.
The approach that I outline below works best when the total time for presoak and initial agitation are greater than the stand development cycles for the two films. I use 3 timers. Timer 1 is dedicated to film # 1’s current process, Timer # 2 is dedicated to film # 2’s current process, and the third timer is used for the agitation cycles. I also recommend numbering the tubes and the timers, to keep track of them and not rely on placement (left or right).
I use a small whiteboard to write down the development plan and erase each step for each film as I complete it. You could accomplish the same thing with a piece of paper and mark through each step as it is completed.

Two Film Development Timeline for Individual Tubes of Film
Step 1 - Film # 1 - presoak for 5 min
Step 4 - Film # 2 - presoak for 5 min
Step 7 - Film # 1 - agitation cycle # 1
Step 9 - Film # 2 - agitation cycle
Step 11 - Film # 1 - agitation cycle # 2
Proceed to step # 15 for film # 1
Step 13 - Film # 2 - agitation cycle # 2
Proceed to step # 15 for film # 2
Step 15 - stop/fix/wash film # 1
Note: I remove my films from the tube and go to trays for stop, fix, and washing. I am currently testing a new method that will simplify this for my mobile darkroom.
Step 16 - stop/fix/wash film # 2

Dear Tim, Interesting project, but I can’t help thinking that you should copy the nova slot tank and transport several sheets in a hanger. I use 3 combi - plan tanks in a tray with an outer tray for hot water temperature control. My UK darkroom attached to the house can drop to 10 deg C.
