    Tony, your homemade 70mm reel (last picture) is a very interesting idea! Having been not so impressed with the handling of plastic reels when developing 116/616 film, I have been on a long term (and so far fruitless) quest for a SS reel. But I think that if I could convince myself that the center section of what you have there could be made rigid and stable enough, I might give a crack at building my own.

    Thanks for posting it and pics. I am trying to make a couple of 70mm devices and just trying to see how others did it. Bought a cheap step motor controller from China and repurposing a motor from an old Konica office printer. Trying to come up with a way to load 70mm bulk efficiently in dark room with some degree of confidence it will be exactly the same every time.

    Going to scrounge through my Wing Lynch Model 4 parts today and see if something strikes my fancy to automate daylight developing.

    If you have a TAP Plastic outlet anywhere near you, they have clear acrylic spriral stock that would be fine for extension I would think. I don't know if they ship.

    Denverdad,

    The wood dowel I used is plenty sturdy! I processed at least 70 rolls with back in the day. You could make a 90mm/122 reel easily. Or use plastic as Patrick suggests.

    Way way overpriced. Jobo didn't sell many of them as they have always been high. But it will process 70mm film.

    Kinderman had a nice tank/reel for 70mm; it sold new for around $200. Also Honeywell/Nikor had a 70mm SS tank/reel that can be had for around $200 or less when they pop up on eBay.

    Yes this is way overpriced, though like you said not a whole lot of those out there. We have a bunch of the tanks, but never seen the reels or loader for 70mm. It does have the advantage of being able to load an 8m length of film which none of the others do, but that might not mean much at this point in time.

    Wow, they do not come up very often! Actually I think the (starting) price is vaguely reasonable as it includes a loader that itself is likely worth $200.

    I think its worth any amount of money as these loaders are so rare....
    I wonder - is there any reel out there that can hold a long roll of 70mm other then the elusive Jobo reels which require a loader..??
