Hi All,

Just wondering if anyone knows of any place that's able to supply 35mm plastic film cores (bobbins) in Australia. We're after the small ones (2 inch diameter).

Cheers for any info!

How many do you need? You could buy them, but a 35mm lab would probably have about a million of them and may just tell you to come and get 'em. Back "in the days", that's where I got mine.

Hello Andrew,

You should be able to get them from Cinevex film lab in Gordon Street, Elsternwick, or direct from the manufacturer Tuscan Industries in Redfern, N.S.W. The blue Tuscan bobbins are suitable for long term archival storage. If there's no money, maybe a post-production house would be a good place to ask.

Good hunting!

I'm curious. Are your Australian cores (bobbins) somehow different from our U.S.-made ones??

What got my attention was the line about some of them being suitable for long-term archive use. What is it about them that makes them more suitable? Are they just larger in diameter, like the 4" cores we/I use for long-term storage. Or, is it something else about them??

If there's a significant difference, could a picture of them be posted here, maybe??

Thanks a lot!!
Ron Yost

In the USA, Kodak FPC Hollywood sells them:

The cores made by Kodak have to be made of inert plastic, or they would affect the unprocessed film. So they are suitable for long term keeping.

As noted, since many labs now ship prints on 4-inch cores, the 3-inch cores the raw stock comes on may be available as surplus.

They are available from Kodak in Australia too, that is where I used to buy them from.

John,

What is the difference between FPC Type K cores and Type Y cores? They appear to be the same.

Also, as much as Kodak loves to support saving the environment (read cyan tracks), why does Kodak not ship their raw stock on the standard 4 inch cores that are used in general distribution? That way there aren't a ton of 3 inch cores being thrown away and killing our planet. Those 4 inch cores could be used on the output end of the processing machines and put into regular circulation. It only makes sense.

The 4-inch lab cores are a relatively recent development. I'll certainly run the idea past the manufacturing folks. I would suspect the exchanges recycle the 4-inch cores back to the labs for use with new prints.

Most cores are recycled, but "used" cores cannot be used for raw stock because of the risk of contamination affecting the photographic properties.

Makes sense, but in your pitch to Kodak you might want to throw in the part about how the depots are having to toss the cores with only 1 drive pin hole in them since they don't fit the later model clip-together reels.

Hello Andrew,
I dont know if you have access to Jack Roe cinema supplies in Australia as they stock all sizes of film bobbins.

no! 2" cores are garbage!
The 3" should be the smallest you use, anything less is going to put a horrible curl in your film.

Here here. 4" is ideal, 3" OK for reels of 1,000 feet or less.

My gut feeling would be to try and find a lab or facilities house which throws them out regularly; you can buy them from suppliers such as Jack Roe but they're not cheap if you get through any significant quantity.

Thanks for reminding me of an issue that makes the 4-inch cores unlikly to be used for raw stock. The drive pin holes tend to weaken the structural strength of the core in resisting "crushed cores" of large rolls during shipping. When a 4000-foot or 6000-foot roll is accidently dropped or hit on its side during shipping, the forces are concentrated on the core, and can actually "crush" the core, or change its center hole enough so it will not fit on the 1-inch unwind spindle on the printer. Kodak actually had to strenthen the 3-inch cores with thicker ribs, which is why there is a "Y" core and a "K" core. Adding holes for the drive pins can weaken the core and make it more susceptable to being "crushed".

You may be able to pick up a batch directly from the exchanges during a junking.
Failing that try the labs as suggested by Phil Grace.
For strength, I'd probably suggest either the Fuji or Agfa raw stock cores. They seem to be much stronger through the ribs and bore than the Kodak ones.

Brad mentions a pitch to Kodak about bore size and laments the exchanges having to ditch cores with 1" drives. The great thing about the 35mm format is the standardisations in place. If the split reel manufacturers can't stick to the standards then maybe it's the reels that need to be chucked.

And it makes heaps of sense to use 4" cores through out the entire film chain as Brad suggests. Great idea. Taking up on cores is fun!
