I have a unicolor drum (that can hold upto 7 35mm reels, well 6 officially but you can make 7 fit), and the uniroller it sits on. My question of course is I cannot find any instructions for it online, and the main thing I need to know is how much fluid am I supposed to use.

ml per....
120 reel
35mm reel

etc.

I tried a 36exp reel with 100ml chemicals, but it didnt seem like it got the center of the reel, anyone know the official ammount of fluid per reel?

I would not worry about the official amount. I would make certain that it fills the tank at least half way with the tank in the horizontal plane.

Well.... here's what I would do... I would figure out the volume of the cylinder

(Pi* R2)*H (Pi= 3.14) (R2= Radius of the inner circle squared) (H=Height of the cylinder).... but I would use 1/2 H, since you really do not want to fill the thing.

This will give you Cubic Inches.... convert it to ml here:

OR.... I would take the cylinder, with the reels in it (unloaded... without film on them), fill it a wee bit over half full of water, and pour it into a measuring cylinder. (This is the 'no math' way)

I did the non mathematic way. to avoid the reels from getting wet, I put them in, and set the plunger up to the appropiate height, removed those reels, and put in a bunch of 35mm reels until it reached the height of the drum, poured water in til it was full, then poured it back out to find it was about 6 cups for the (3) 120 and (1) 35mm reel, so took 3 cups converted to milileters (709ml approx) , figured 750ml was fine ( was dead to the middle almost), so ya that works

Why not just fill the cylindar with water and then measure that?

She says it at the last bit of her post, which is what I did was fill it, (With reels inside), measure it, and cut that ammount in half (or approximatly so).
