Brad.. I am sure that I am not the first one to ask this question. But I could not find a reply using the search.

We have started using Film-Guard along with our Kelmar units, and really love the results. But we have one small problem, and that is
in one of the projectors (Vic-9's) when using the Film-Guard, we are getting alot of gate chatter and a bouncing on the screen. I read about keeping the levels of Film Gaurd down on the media pads, which we have been real careful not to over saturate them. Any ideas that may aid me in correcting this problem. We are running 17 screens. 16 with Vic 9's, one with a Vic 5. This one projector (V9) sure does not like it. Thanks

Simple, there is not enough gate tension to steady the film. Since this is specific to one particular projector, this is definitely a misaligned or worn gate on that one unit. Having never worked with a V9, hopefully Jack Johnston or someone who is familiar with those can tell you the fix.

Increasing gate tension should work. Check to make sure that the pressure pads are evenly worn since the gate sometimes wears more on one side versus the other.

Thanks for the information.... I have increased the pressure on the pads....and this does not work. I think I need to look into replacing the pads. If anyone else has some ideas I would welcome them

Grrrrrrrrrrrrrrrrrrrrrr,

My god Greg, read Bob's original post again.

He said
'I read about keeping the levels of Film Gaurd down on the media pads, which we have been real careful not to over saturate them.'

You said (in your one solution)
'Are you using to much FG? Some times I get carried away with how much I put on and have the same problem.'

What were you thinking? - Sorry, but that sort of reply bugs me, Gordon tends to do it as well.

I would suggest to Bob that he wait until the film/movie is ran through a different projector, or a different film is run through the problem projector.
Bob you stated 'We have started using Film-Guard along with our Kelmar units' but never mention for how long.

TO ALL
I am in a long drawn out argument with the two major cinema chains in Australia.
So far it has been reduced down to the fact that the person who say's we can or can not use Film guard has a personal
problem with Brad, because this person was having trouble on the forums.

The latest was to get our head technical guy to send a nation wide warning to use nothing other than 'Johnsons Boot Polish'
to edge wax prints. Because other cinema's have been complaining to distibutors about sticky prints coming back to them.
If we dont stop using this stuff we will be hunted down.

I put this warning into context that it is refering to Film Guard, because a week earlier a location sent out an email asking where to
get FilmGuard from, the reply to the emailer was to simply bag the 'over priced' product and the forums, without any other reason.

As I said this is an ongoing issue, I will follow it through even if it means they tell me to stop working for them.

I simply request it gets tried by the the powers to be. I've tried it, in it's most simple form,'edge waxing' type use. Instanting all my projectionist's are LESS stressed, about stactic cling wrap arounds.

Bill.

PS I'd like to see a thread called Hmm 'Filmguard Yes/No/Why'
My biggest loss, was the fact that Kodak will only 'approve' products THEY make.
They market stuff under a different brand name, and only that can be 'kodak' approved.

PPS, to John Wilson, I will drop in soon, please email ICQ me when you are mostly on at the Ritz,(Sat nites are cool for me) my main question is :
What is the effect on film when it has been film guarded then, moves on to another place and they dont Filmguard it?
Does it dry up then start to get sticky? - Perhaps this is their concern. It is also Bretts main concern at Cremorne.
However, Im sure I read that Brad has archived (filmguarded film) that runs fine after many years (10).

Hey Bill... I have switched out that film for another on the problem projector, and all was OK. It only chatters and bounces when using the FG. Until we replace the pressure pads I guess I will have to screen it that way. Funny though, after a film is FG'rd and ran without using the Kelmar unit it runs OK (same print that chattered using the cleaner.) Anyway to all, thanks for the information, it is nice to know that their are PROFESSIONALS out there who care about our trade and are willing to share experiences to aid others.

Bill
And the bottom line is if you work for an employerer there policy is the final policy

Kodak on there site lists some materials tested by a third party Lipsner Smith but for some reason seems unwilling to actually test themselves and approve any proprietary cleaners.

Why doesn't Kodak endorse certain products? Because if they endorse one then other manufacturers of different products get all pissy and could possibly even file a lawsuit. Of course that won't stop Kodak from clearly endorsing Johnson's Paste Wax to death (anyone want to argue that Johnson's Pastewax does ANYTHING better or even as good as FilmGuard as far as film applications are concerned? Any takers?). Nearly all companies in the US are afraid to do certain things that would be for the benefit of everyone because they fear lawsuits. Sad. Company lawyers suck.

Johnson's Paste Wax was suggested years ago as an EMERGENCY method of providing print lubrication for projectors that had severe abrasion. It was clearly NOT "endorsed" as a regular film treatment:
http://www.kodak.com/country/US/en/motion/support/faq/dusting.shtml

There are many proprietary film treatments, and it would be difficult and expensive to thoroughly test all, and unfair to single out a few. No Kodak lawyers were involved in this common-sense decision. Independent test labs (e.g., Image Permanance Institute of Rochester Institute of Technology) can run tests to "certify" the long term effects of any film treatment, and it is the responsibility of the company making the film treatment to have it independently certified.

Bill, there are no negative effects from running FilmGuarded prints. How do I know this since we are the only cinema running it? (GOD KNOWS WHY, DAISY!) I'll tell you how I know...because we had that print of Moulin Rouge that left and came back several times. Each screening after it came back there was only one thing missing from the print that would normally be on EVERY print of a second run you get in...

...it was absolutely SPOTLESS.

It is absolutely astounding to me that the chains haven't cottoned onto this amazing product. As I've said before, there are none so blind as those who will not see.

Let me pose this question to all other cinemas running Episode 2 in Australia (or the rest of the world if you like...) In the scenes where Obi Wan goes to inspect the Clone Army and he's talking to that Digital tall person, everything is white, right?

Is it ALL white? Do you see any specks of dust AT ALL? Even one? Several? Lots?

How do you think it will look in a week's time? Two? Six weeks? Will it look like crap or just a bit dirty?

Do you think George Lucas put those scenes in there to show off how clean his Digital Cinemas look as he knew film could never keep those scenes clean? I certainly do.

I looked at this scene again today on both of my prints. I looked to see a single speck of dirt. I tried, damn it I really did try.

There's nothing.

Just image. No kidding. And you know what else? By using this product with the Kelmar cleaners, I KNOW (Not a guess or a possibility) I KNOW that on the last day of our run it will STILL be completely free of a single speck of dirt.

Now, if there are any other theatres who can make this claim, let me know where you are and I'll come take a look. I would be very interested to see this. I strongly believe this will not be the case. There's only one way to do it, the customers appreciate it and we get return business PURELY on the FACT that our customers KNOW that our prints will not look trashed by dust and crap around the splices whenever they come to see a film at the Ritz.

I again extend an open invitation to whomever would like to see this in action to call me either at the Randwick Ritz, email me or telephone me on 0408 446 670. Come and take a look. Ray Derreck, Owner and founder of Panalogic Corporation took up my invitation. He took one look at it and went straight back to email Brad to get the Australasian rights to distribute it.

So, if anyone in Australia or New Zealand would like some to try, email him or call him. His email is on the site, just do a search.

Sorry to take so long with this, but it's mightily annoying that those who've never seen it, seen what it does or what it can do go about complaining that 'theatres are complaining of sticky prints' and say don't use it or get the sack if you do, yet then go ahead and say use Johnson's Wax! To automatically suggest it MUST be filmguard is such a CRAP notion that it's just unbelievable. To those people I say 'FilmGuard STOPS prints from sticking, it doesn't make them stick together'. It also keeps ads and trailers in as-new condition for their entire run. Come take a look.

So, finally, if you would like some FG, give Ray a call. You'll never look back.

Now, if we could just get Brad to develop a different version that would get rid of Episode 2's WHITE specks, we'll be right.

Bob...
The V9 is an older version of our current V5. It uses the same gate as the V5. There should be two thumb screws on the lens side of the gate: clockwise to increase tension, counter to decrease. You might want to look at the gate plate. This projector mechanism was made in the 1975/76 timeframe, the plate could just be worn out. #E506 for std gate plate (short), #01750 for gate plate with side pusher (helps prevent weave) and #D01650 gate plate (long) with side pusher. Hope this helps.

Important Correction

Regarding my original post, I mentioned that both Star Wars EpI and Starwars Ep II premiers at Fox Studios Australia broke. This was completely wrong.

When Fox Studios screen premiers, it is on up to 11 Cinemaxx screens.
And nothing has gone wrong in years.
(I think minimum specs for Cinemaxx is 20metre screen / Stadium seating /DTSorSRD / 500 seats)

The head/chief projectionist there is a good friend of mine, and I made a big mistake by taking the word
of one of my projectionist’s friend heard on the news that SW:EPII broke.

Since Fox Studios screen Red Carpet premiers with the Stars/Directors/Producers attending and there
are no complaints from these people about anything, why should they need filmguard?

Also the product condemmed was WD-40, not Filmguard.
(Using Wd-40 on film, Well now I know why they were so serious)
