Brad,

Do I understand this right, your your changing the white media fabric to something a little courser. Is there any change in the length (that is run time) of the rolls? Please don't tell me you shortened them.

What's the best cloth to use when applying to older, dirty/oily prints by hand? I tried the 100% cotton Webril wipes, but they kept shedding every time I hit a tape repair.

Also, is it possible to put on too much Filmguard? I tend to change and re-wet the cloth about every 1000 feet, and the last print I cleaned had noticeable blotches on projection.

I also hand clean the heads and tails of old prints during inspection and repair. The crud that comes off is incredible. The mechanical cleaners (running 2000' reels and changeovers) can then handle the interior of the reels.

I use a fabric called white cotton interlock. Looks like white undershirt fabric. You can buy it at any big fabric retailer. It's about 54" wide and costs about $3.50 a running yard. Very little shedding. Cut it up into 3" or so squares. Makes a big pile of cleaning pads for very little cost.

Pete - The new white rolls of media are much longer.

Bernie - Methinks you are using too much.

For some reason, our print of SINBAD was shedding very badly. One pass through the projector left dirt all over the place. FilmGuard sorted that out.

I circulated your concern within our group, and no other incidents of unusual shedding have been reported on "Sinbad". However, Mark DeLettera suggested that very high humidity may be a factor in your case. He checked, and the humidity in the Bahamas has often been above 75% RH during the past few days. As you know, excessive humidity can make the gelatin emulsion soft and sticky. In addition to lubricating the print, you should try to keep the booth humidity in the recommended 50 to 60 percent range.

Someone asked how to wind non-FT media onto the FT cores. The way I do this is as follows (using a Kelmar cleaner):

Put the film cleaner on the table with the big roller to the right.
Put the non FT media pad on the TOP payout spindle with the media coming off the left side of the roll.
Put the FT core on the BOTTOM payout spindle, slotted site up.
Pull the media down and wrap it around the bottom of the FT core and pull it tight (don't tape it!)
Put the payout spindle cap on the TOP payout spindle (the one with the media on it) to hold the media in place.
Insert the slotted end of a 2nd FT core into the slotted end of the one on the bottom payout spindle.
Wind all the media on to the FT core.
Throw the carboard core away.
Repeat.

Now you have two rolls of media on FT cores. If you do this enough, you'll start to get pain in your wrist an forearm. A theater down the road taped a FT core to a cordless screwdriver, and uses that to turn the media onto the core.

That procedure for using other brands of media is also in the instructions, with pictures too. I wonder what the percentage is of people who actually read those. Hmmmmmmmmm.

Feh. People can't be bothered to read. Not only that, but the FilmGuard instructions contain way more than two sentences, so it requires waaaay too much time for people to devote. Their lives are important and can not be wasted reading and comprehending.

Wow, John...Thanks for checking on my SINBAD situation. I wasn't expecting that. I appreciate it.

Trouble with the humidity theory is that SINBAD was the only movie affected...and also that particular booth is airconditioned very nicely.

I actually suspect the projector. I will probably visit that theatre tomorrow morning and see what fate befell the new movie that started in there today. (I've been off-island doing work at another theatre.)

I've had some time to mull it over and money is now on the intermittent since that's where the pileup of debris began and where the collection was greatest. This, by the way is my "loud intermittent" which you may recall reading about. As it pertains to this shedding problem, I will begin by investigating the pressure on the shoe.

Thanks again.

Brad, Joe -- make the video and enclose a copy on CD-ROM with each bottle of FG.

Nah. It won't be a CD-ROM. It'll be a 70mm print.

It comes with instructions?? I never noticed.

I did however notice that all of the bottles I receive have a strange triangular shape to them when they come out of the box. Brad, you don't squeeze all the bottles before you ship them out, do you? [Big Grin]

It happens during storage. Perfectly normal.

(The instructions come wrapped around the bottle. Maybe we could start folding them up and tucking them in a fold of the box? [Wink]

Bah. You're only half-right, joe. The film-guard instructions contain two PAGES, which is WAY more information than needed for a bottle of liquid. The redundancy factor also takes effect. If something tells me something is "very important" or that I "must" do something more than once, it goes in the trash!!

Oh, by the way, I have a question about applying this stuff to a print... [Wink]

Brad -- Maybe you should put the instructions IN the bottle...

=TMP=

P.S. Don't squeeze the Film-Guard!

I'm joking about not seeing the instructions. Actually I like the instructions, particularly the FAQs. I had a new GM tell me that the white streaks were bad and we were doing something wrong because it wasn't supposed to do that, and it never did that for him before.

FAQ #1... White streaks are normal. [Smile]
