hehehehehe I just knew that would get Mark going.

By the way Mr. Steve, it's one thing to say a machine isn't forgiving of incompetent operators, but if a machine can be operated without damaging film, any damaged film that comes out of it is operator error. That's pretty cut and dry. Personally I've seen FAR more damaged film come out of Christie projector heads than any other, but again it's due to improper threading by retards who believe in that stupid "2 finger rule" thing. [Roll Eyes]

(Speaking of which, on the JJ I run acetate under the loop stabilizer roller and polyester over it. Think about it. [Wink] )

We all know you love your AAIIs, Mark. Don't worry, every one of those things I run across I will be sure and give you a call so you can buy them, since apparently you are one of the few who knows how to make then produce *what I would consider* to be a truly steady image. I've never seen it.

Brad,

When I say damaged film I mean 70mm, not 35mm. The JJ does quite well with 35mm, I like it better for that gauge. You're welcome to come out anytime I'm not on the road, just give a call and let me know.

Two of the biggest things one can do to get them to run really steady and with perfect focus is the the James Bond compound curved gate runer and having a gauge made up to properly adjust the lateral guide roller. The steadiness is great with the original runner but focus is not with largre lamps. I don't know anyone else that has bothered to make a gauge. We just ordered another batch of the gate runners to have in stock.

I know what you meant, just teasing you anyway.

Personally, anyone who converts a JJ and doesn't replace the upper loop's 35mm pad roller for a 70mm one is just asking for trouble. If you simply do that, the whole argument is gone, and it takes less than a minute to do.

Brad, you mussent have experienced the reinforcement ridge on the upper loop stabilizer...it will scratch your film on the frame line...thread up any way you want...it is up to the gods of humidity.

As to the lower sabilizer roller...I thread all 35mm film stocks under, 70mm over.

Can the JJ be made to run scratch free? Absolutely...I've done it for decades. Are they like that out of the crate? Not necessarily. Some of the misalignments from bad machining can not be overcome (if they bore the bearing receivers wrong, they are wrong).

Mark as for the AA2 mag stabilizers...I've yet to see one where you can't see the film fluttering going by the head...and on tones pick it off. All they needed to do was create a natural tension like was done on the JJ and most dual capspin tape decks by changing the diameter of one roller and the weight of the sabilizers.

Actually the Showscam guide fingers work wonders for that part of the film path. MOst hate them though as you have to look at what you're doing when you thread up. Thet also DRASTICALLY reduce the running noise of the machine. I used the 35mm section of them on my VV machine to stabilize the loop exitig from the movement. That machine has never scratched a frame of film.

Donno Steve, On the four or five machines I've run mag on I've never seen the problemm nor with 70mm DTS.

Steve, in most good sized auditoriums I remove that roller entirely, as the loop needs to be made small to ensure precise sound sync. It's in small auditoriums and my screening room that I use them (so I can make a larger lower loop), and never in many years have I seen a hint of scratching, including some of the extreme torture testing that I did in my screening room when selecting the fabric for our current line of media.

2. The DP-70 is the ONLY projector to actually have a REAL oil filtering system including magnets inside both the oil filter and movement to catch metal particles. No other machine has this. Ths X-L oil screen is not a filter

Don't Cinnemechannica V-8's have an oil filter/magnet assembly also? I believe it is located behind the sightglass in the upper righthand corner of the machine.

Yes the V8 has a bar magnet in the sight glass that one is advised to remove if you plan to run a lot of mag 70mm prints as it is in line with the film path

Ernemann E-15, on some machines, the oil fill screw is also a magnet.

The DP-70 definately has the tightest mesh oil filter screen I've ever seen in a projector. Much much finer that in the VIC-8's that I work with. The VIC-8 is also lacking a particle magnet in the intermittent.

Aaron,
I don't think I ever heard if you solved your film path noise problem on your Simplex's. I had some questions on the type of trap / gates that were put in. If you would like to e-mail me with a phone number perhaps we could chat. I may have some things you can try.

Mr. Prather should be listened to on anything having to do with Simplex's. Hi Dick! I was the first manager at the Metro and worked for Larry Moyer in Portland. I believe we have a common aquatance in one Pete Kerchinsky who now works at the Metro which has many projectors you have rebuilt. As I recall a couple of your rebuilds are at the Varsity as well. Im now at Landmarks Guild 45th in Seattle. I hope all is well with you. Dick does a great job with Simplex projectors! Since that is what I learned on I will always have a soft spot in my heart for 50's vintage Xls. I currently have two Norelco AAIIs which, like Mark, I have come to love. They require oil and new bands and thats about it. Especially when running 70mm.
