I've used 120 and 35mm Hewes reels in a 1500 series JOBO tank, the 1520+1530+1530 tank plus a SS 1564 center core and a modified plugged light trap and a 1505 cog in the tank lid. The 1564 SS center core will hold 8-35mm reels or 5-120 reels, but not the 220 Hewes reel, that reel can take 1-220 or 1-120 roll of film, but not 2-120 rolls.
The extra weight of the SS reels and core will place excess strain on the older motors of the CPP2, the later model CPP2s have a heavier motor and can take it. You will need a JOBO lift to effectively work with this setup.
