Stephen, can you measure the diameter of those reels in inches?
Inches! What are they? [Confused]

No problem Brad, the cinema's only five minutes walk down the road, so I went down there at lunchtime and measured one. Converting to inches they're just very slightly under 24 1/4.

A lot of places use them for building up half prints for transfer to towers; the exchangeable centres are quite useful if you have projectors and rewind bench with 9mm spindles, but a tower with 1/2 inch, for example.

They are quite robust, except for the centres working loose; if you don't need to change them then it's probably best to glue them in. If you bend the flanges inwards so they touch, or a similar distance outwards, then they just spring back. If you keep them bent for a long time, e.g. put them flat in a storeroom and pile heavy things on top of them for a few weeks, then they will eventually stay set like that. Yes, there are people who do that sort of thing. [Roll Eyes]

They're quite lightweight, the centres coming loose and the fact that you can't see how much film is left are the main things that I don't like about them. When the film gets beyond the holes in the flanges, there's probably about five minutes left to run, with polyester. We tend to use these for the second half of a feature, and for takeup, and use the Kinoton wire spools for the first half, so you can easily see how close you are to a changeover. Quite often the projectionist running the film won't be the one that made up the print, and won't have seen it before, so it's useful to be able to see easily how close to the end of the reel you are. I suppose you could machine away part of the flange, so you could see it, if this is a problem.

This is a picture of part of the spool:

You can just about see the removable centre, it's about an inch in diameter. This is a 9mm centre, and the drive pin hole falls half on the main part of the spool and half on the centre piece; this is why the spool won't fit on if the centre has rotated slightly. This wouldn't be a problem with a 5/16 hole with keyway; and I don't think it is with 1/2 inch, where the drive pin is further out. The Kinoton site lists both American and European spindles, so I think yours may be different to ours, but I don't know how.
