IMHO it would be Cinemeccanicca, and Christie that would be the most expensive present day machines to maintain. The exchange rate between the US and Italy is piss poor and has almost always been that way. The Christie does not have a field servicable intermittant and they fail regularly making the cost of their machines very high over the long haul. Christie also charges more to drop ship parts directly to a theater adding to the already high parts cost.

Kinoton/Norelco may have high parts cost but they rarely need any parts. Just normal film path parts that are not very expensive, and change the oil regularly. FP-20's and DP-70's are probably THE most reliable projectors ever built. Indeed the Ballantyne projector utilized many of the DP-70's and the FP-20's features. The verticle shaft with gears ground into it from the DP-70, the framing coupler, although for unknown reasons Ballantyne went the plastic route here.The bronze coupler in the Norelco FP series lasts forever. Indeed Norelco/ Kinoton, Simplex, Century, Ballantyne when properly maintained will generally be the most trouble free and least cost to maintain of the bunch.
The key here is to keep the machinery spotless and use a good synthetic machinery oil instead of regular projector oil. Synthetics will lubricate better, last longer and will not break down like regular oil does. LaVezzi oil is a good choice here. Also do not use Lubriplate on any gears, use Super Lube instead.

Ballantyne uses plastic (actually fiber) gears on the intermittents and shutter trains (Pat, correct me if I'm wrong) to protect the projector's metal vertical shaft. The shaft is "non-field replaceable", and in the event of a component failure, the fiber gears are designed to "break first".

If the intermittent locks up it will stop the machine cold. The shutter (as a result of momentum) will still want to spin. The fiber gear will simply disintegrate (cheap and easy to fix) instead of taking a chunk out of the shaft (send it to the factory).

Century has to be my all time favorite projector to place in the field. You can abuse them for years! While people make fun of Ballantyne oil leaks, I have never seen a Simplex that didn't have a bucket or paint roller tray under it to protect the floor! (LOL)

Of the three, Ballantynes are the easiest to service.

I am still trying to convince an "old codger" tech of ours to post here. I think he eventually will. His name is Mike McKee and when you see him you should ask him how he got the name "Cross-eyed Mike".

He started out hating Ballantynes, but now he likes them.

Hiya;
This is the real Pat Moore, by the way...
Those are delrin gears on the Intermittent and the shutter. We've used steel in various special venue applications, but delrin is in all standard cinema projectors.
Vertical Shaft -- hmm. They can be removed in the field, Russ -- maybe not the most fun thing to do but they can be taken out. In early Ballantyne's the bearing end caps were eccentric, but somewhere in the late 80's we took that adjustment out.

I sort of feel there's a quality vs. labor time thing with projectors. For example, a Century is fairly inexpensive; so are the parts. But it's also fairly easy to fix. Personally, I feel they are also high maintaince (no oil bath.) Their reliabilty is like a Volkswagon's.

I think Simplexes are better, but they are more expensive to buy. Also, they are more involved to repair.

Now, (going against the grain!) I've had very good luck with Cinemeccanicca (V8's and V9's.) They are more expensive and the parts are out-of-sight. Hardly ever had to fix any big problems. But, one time we had to change a shutter shaft on a V8, and holy smokes! What a major job- everything has to come apart. Took all day.

So, what's better? A cheap projector that's easy to fix, or an expensive one that takes all day?

On my previous ramblings: They will probably never get rid of Simplex or Century!

At my past two (daytime) jobs, they made stuff in big quanities. So, reducing anything "redundent" was consitered good. And I must admit, I'm in that same mode. But, it is true that new tooling costs may be more than would be saved than if existing tooling were kept and used.

At one place where I worked, I designed a 19" rack to hold some fiber-optic equipment. There was a question of how it should be grounded to meet the (then new) EEC rules (the equivalent of USA's FCC, UL, etc.) We wanted to meet those rules. It allows you to put the "CE" mark on your equipment, and without it, you can't sell a thing in Europe. All I wanted to do was punch a 0.125" hole in a panel, so field people could mount a grounding stud later (and not have to drill a hole.)

At the design review, everyone was going; "Are you crazy?! That hole will add 15 cents to every panel!" We were going to make about 5000 panels. The accountants had everything figured out to the penny to make the bid and were reluctant to spend the extra money.

John,
Actually the Century is about 1200.00 higher in list price that the equivelent Simplex.
Either will run for many years if properly maintained. One advantage to the Simplex is that it holds allot more oil than a Century can. More frequent oil changes in the Century and keeping the gear train clean and lubed with Super Lube will contribute to its long life. I advocate synthetic oil and lubes in any situation as they have better lubricating properties and are simply better in the long run.
Either machine can have problems. The Century if not maintained properly WILL have more problems than a Simplex do to no oil bath. However there are the small fibre gears in a Simplex intermittent that do shear if there is a serious film pile up, or if the movement locks up. These are in reality mechanical fuses so the rest of the gear train does does not suffer the same fate.

Getting back to the earlier part of this thread...........

I too work for one of the worlds largest cinema chains as David Johnson does (I used to work with him but that's another story!). We use Christie, Kinoton and Cinemeccanica as our main brands but also have just about everything else made in the last 30 years.

We have had a few disasterous Christie installations (5 Ultramittants in 12 months), but some very solid ones too. One Christie, located close to me, has never skipped a beat in 5 years and it is in a remote projection booth with little daily attention other than cleans and threads.

As a large chain we continue to purchase from several manufacturers in projection and sound (Dolby mostly but also DTS and SDDS). The absolute keys to running ANY equipment is professional installation and most importantly experienced, dedicated projection staff. In most of our locations in this country we now have at least one projectionist with 20 years plus experience.

I will always hire and train people who are interested and dedicated to the craft of cinema projection. Film has a lot of life in it yet. The biggest single thing that any cinema can do to improve their presentation is have a projectionist who knows how to clean (lenses, port glasses, mirrors, film path, platter rollers, payouts) thread-up consistantly, understand what screen presentation is and maintain the equipment(dolby tone once per fortnight, oil & belt changes general adjustments).

And Oh, one very important thing, check the auditoriums once per shift for sound level, temperature and a patrons view of focus.

A Century costs more than a Simplex? That seems strange. I would think that the oil bath design would make it cost more.

I can't stand it when I have a nice theory all worked out in my head, but then someone wrecks it using actual facts! Darn...!

I guess we all have to pay for ORC screwing the Century up. Strong had a big job ob its hands when they took it over.
