Great deal, nick. You're set to go.
Now the tricky part will be loading the spiral in the dark. It doesn't load like a 35mm or 120 reel. It's considerably more tedious.
I suggest you nail a small 1x1 inch piece of wood to a larger stable wooden base, then drive a small nail into the 1x1 inch piece. Put the lower half of the spiral on the nail. You'll be able to turn it freely with minimal friction and without it wandering all over your counter top.
Leave the top disc off to get started. Attach the film to the hub through the slits (from inside to outside, then back in... you'll see what I mean) and take a half turn clockwise around the hub wall. Twist the film over to the left so it will feed flat from the outside of the reel. Maintain some slight tension on the film against the outer edge of the reel. Put the top disc on while maintaining the tension on the film, then screw it down, but not too tight. Now turn the reel clockwise, feeding the tensioned film in flat from the outer edge until the entire length is in the reel. Tighten the top disc down snugly, but don't over tighten.
It's easier said than done. Practice in the light with some scrap film. You will think you need three hands. If you are dealing with long film, mount a 16mm movie film rewind on the base board about a foot to the right of the nail. You might then want to raise the height of spiral seat and nail to about the height of the spindle on the film rewind. Transfer your film to a small 16mm movie film reel or camera daylight spool. You will then be able to feed the film spiral from the rewind. Long lengths of film tend to get hopelessly tangled up in the dark if you don't have a secure way to handle them.
Some other tips: If you are developing single perf film, load the perfs down into the groove. It's best if emulsion faces in, but either way will work.
Very occasionally, the film will fail to develop in the perf area down in the groove because it sticks to the plastic. To avoid this, don't pour the developer into the dry loaded tank through the light trap. Instead, with the lights off, put the developer in the tank, put the spiral in and agitate immediately (turning clockwise only, somewhat firmly) to ensure the film is evenly and quickly wetted. Then put the lid on. You can then process with the lights on.
Never agitate by turning the spiral anti-clockwise. You will unseat the film and make it come out of the spiral. Turn clockwise only, and firmly.
Good luck. Let me know if you run into problems.
