I have a electrical makeup/break down table. I would like to break down the trailers I have back on to the plastic cores they came with. I know I should put them on bigger cores but at this moment in time, I don't have any. How can I put the trailer back on the core. I keep on hearing trailer flange - what's a trailer flange... Stupid Question #1099. I made up the trailers by holding a pencil through the core and letting the take up platter go. I also pulled a bit on the pencil to keep up some tension so that it's not slack on the platter.

A trailer flange looks kind of like a reel if you were to cut one side off (or like half a technicolor reel!). It's just a metal disk with a 1" diameter metal cylinder that you slide the trailer core onto. The entire thing fits on a rewind bench, just like a reel. You then rewind the film carefully onto the trailer core, tape down the end, and remove the whole thing. They also make these for the larger 2-4" cores, although I personally prefer to use a proper "spin-apart" split reel for this purpose.

Look on the tips page at "cutting trailers properly". There are pictures of a trailer flange and the correct way (and incorrect ways) of rewinding trailers back onto the cores.

LM Editorial Supply has 35mm split reels for sale -- L&M Editorial, Inc., 219 West Palm Ave., Burbank, CA 91502 , (818)842-5332, (800)840-5332, Fax (818)842-5803 :

Likewise, Goldberg Brothers makes split reels and film handling equipment that should be available though most theatre dealers:

Winding film on a core or hub without the proper handling equipment is very likely to cinch or dish the film, or cause a loose or uneven wind. IMHO, lack of proper equipment to handle rolls on cores or hubs is one of the main reasons trailers look so worn and dirty in some theatres. Please get the proper equipment to "Do Film Right"!

I always had good luck winding up trailers the way that the tips section says too. If you have the autostop roller I would certainly do it this way. if you dont just break all the trailers to an extra house reel and then take them from the reel to the core at the bench.

Hmmm.
CPI lists a 'Make Up Shaft Adaptor 5/16"- 1/2"' at $12, but that doesn't sound like the same thing as a trailer flange. Does CPI sell trailer flanges?

That sounds like a sleeve to convert a 5/16" shaft on a rewind table to a 1/2" shaft.

To get a little off topic.

Does anyone sell an adaptor for a 1/2" shaft hub reel for say a Christie MUT? I know I can flip the shaft around, I just don't carry a screwdriver with me all the time.
