As to the "why" of my question ... simple: I own two plastic reels and a plastic tank that can hold one roll of 120 or two rolls of 35mm. I'd like to develop two rolls of 120 at a time, but don't want to spend any more money than I absolutely need to.
skahde said:Your plastic reel will most probably hold two 120s. Just spool in #1 as far as it will go and let #2 follow just untill it is held completely. Two 120s are about the same length as one 135.
dpneal said:Sorry if my language was ambiguous. I have two adjustable plastic reels and a single plastic tank -- the reels work great with 120, the only problem is that the tank is too small to hold two reels set to hold 120!

Ed Sukach said:It would help a great deal if we knew just *which* reels are in question. Both the JOBO and Paterson reels, when "set to 120" will hold two rolls of 120 film on a single reel - one behind the other in the same track - or one roll of 220.

Why? Again it really depends upon the dimensions of both the reels and the tanks.. There are some large diameter plastic reels around (Jobo 2501 and 2502 for example). and there are some small form plastic reels (Jobo 1500 series) and then some a little bit larger in diameter (Paterson, A-P knock-offs) and then there are stainless steels reels in all these rough dimensions (Hewes even makes a few in Jobo 1500 series dimensions with normal and large hole to fit the standard Jobo column). There are then some stainless reels that are large in diameter. I have an Ilford Autowinder 35mm tank (designed for 72 exposure like the Jobo 2501) whose diameter is quite a bit larger than other inversion tanks (and en-par with the pre-WW-II Jobo "rotation" tanks). A 1500 reels would just rattle around in that steel tank...Flotsam said:But of course the only way to get one of those Jobo reels into a stainless tank is to use a large hammer.
