Short End Spooling

If there are no sides it is probably on a core instead.
I bought 200 feet of short ends and it came on a spool that I can't identify in the dark... It feels to be a small side less spool. ...
If you are careful and have rewinds in the dark, you can wind it on to a reel or spool, and then wind it back again on to the final spool, to be oriented the right way round to fit the camera. If it is really 200 feet you will have to divide it between two 100' spools. If you are not experienced with handling core loads you should likely use a split reel, to stop the film roll from spilling, and also to convert from the 1" inside diameter of the core to the 5/16" diameter rewind shaft.
A camera spool normally holds 109 feet, to give an extra 6 feet for loading and 3 for unloading. So one spool might wind up being full length and the other not. If using an HFC geared rewind, 109' corresponds to about 46-1/2 turns of the crank handle.
While rewinding, you will of course be subjecting the film to possible static marks, picking up dust which will photograph on the film or maybe lodge as hairs in the camera gate, and fogging if the room is not totally dark.
Empty camera spools can generally be had at no charge from your friendly local film lab. Check for bent flanges so the film doesn't catch and cause a film jam. Cheers,

Now I just need my light meter to come in.
That's 46 1/2 turns on the rewind on a 8:1 shaft, and not the 1:1 right?

No, you are confused. As I said, this is specific to an HFC 2000' rewind crank, not to a camera. The HFC has an odd ratio, I calculated it once but forget, something like 4-1/7 to 1 or thereabouts.
That's 46 1/2 turns on the rewind on a 8:1 shaft, and not the 1:1 right?...
The Bolex 8-frame shaft moves 8 frames per turn, if you are going through the sprockets, and there are 40 frames per foot, so this would need 545 turns to crank through 109 feet. This is a lot more cranking than using a rewind.

I have made my own Kodak labels up with the film type, processing info and space to write "exposed" and other notes on. The lab I have been using, ColorLab in MD has been very gracious in sending me half a dozen spools free every time I send in rolls for processing. As I have about 17 400' cans in the fridge, this has been a great help getting me down to 100' daylight loads. They don't seem to mind as I keep sending them more and more film that way. I always send them a nice note thanking them too.
