Well I thought I’d keep you up dated as I finally got around to using my pair of Spectra’s at the weekend. And to my delight I am very impressed with what I saw.

I set up the stand, which is really easy to do thou it comes in three parts. Attached the main projector on top. And fitted the spool boxes connected the sound cable to the matching amplifier.

And away I go, I thought I’d try out a reel of Technicolor film and I was blown away on how good the picture looked. The picture was rock steady and using the 1000watt Xenon lamp was a marvel. I found the controls of the projector really easy to use and in an easy location to get too. One button just to press the xenon lamp and sound lamp on at the same time. And a toggle switch to get the motor running.

Even the sound was very loud and crisp and detailed using a pair of JBL Speakers. The little exciter lamps I found funny looking bulbs. Thou they are just normal bayonet fitting.

My next step is to use both as a pair to show a feature and see how easy it really is to do change over’s with these machines. The main power supply to both projectors and Xenon lamp plays a part.

I must admit they look more modern and up to date compared to the FP3 Philips which I had before these which had a spool capacity of an hour.

I must admit these are the machines to go for if you want to start showing 35mm films for domestic use in your own living room but having the added advantage of storing it away and if needed is easily mobile.

I did note that the cooling fans are the nosiest compared to the running of the motor or even having film running through it. But placing a monitor speaker underneath the projector can easily cut this out.

With spare parts still available for this projector from the company in China that still sell a similar model. All parts are interchangeable and will fit older versions of the same model.

Photo's will indeed follow [Smile]

Hi Mike,

The noise level i would say would be probably the same as a 16mm projector (Fumeo X900) and more importantly how big your room is.

I did think a Philips FP3 was quiet as it runs like a sewing machine and to i heard the Spectra's. I think this is down to it being more compact and everthing enclosed in a box.

Robert, I'm glad you finally found your perfect toys. I guess you won't be looking for 9.2 mm spindle split reels anymore.
Let us know as soon as you start playing with change-overs.

Hi Robert
I am in the throws of buying a pair from the factory in Shanghi, they even wanted to know if I would like to be a NZ agent for them, that ways I would buy them at a discount price!
I believe the only wee problem with them is the lens barrel size and that one must get sleeves made up if you were to use different makes of lenses other than the ones that come with the projectors, they also come with a anamprphic lens holder that swings up out of the way when not in use.
It would be nice to see some pics of your machine/s Robert!

Hi Patrick,

Good to hear you are going down that route; strangely enough I was to go down that route myself until I found a pair in the UK. So I guess you could say I saved on the shipping costs at least as it’s the complete kit. With an extra 7 1000w Xenon bulbs.

Correct me if I am wrong but I think the lens and the barrel size is 62.5mm, which is not the normal size as, used in local cinemas, which is 70.6mm. Thou because it is portable like the Philips FP3 it is the standard size.

Not sure if you can get step down sleeves for this, so you will be limited on what you can get. Thou I know that ISCO and Schneider lens which I have two of, still do make this size and if you are lucky you can also get them second hand from time to time. But I highly recommend you buy an ISCO or Schneider lenses, as this is the best lens that money can buy in quality brightness and sharpness. The Schneider being the better of the two.

Yes these come with pretty nifty scope lens holders that just easily swing in and out of place when needed. Depending on where you will be using these I use a Kowa 16D lens which gives great results as you will also come to find that most scope lens for cinema’s are for long throw only. So I use the Kowa because I am limited on how far I can go back.

I have a spare 70mm ISCO Ultrastar in 62.5 mm diameter if you're interested.
Also have a 95 mm in 70.6 diameter.
150 euros each.

I will probably get some sleves turned up out of aluminium.
One problem with the machines is they still come out new with a exciter lamp instead of the red reader system to use when screening modern 35mm prints, so I will need to do a home made job on them using a red l.e.d mounted where the exciter lamp would sit.
I hope you get alot of enjoyment from your machines Robert!, are yours the grey ones? as I believe they also come out in black and also white.

Yes these are the grey ones which I think look nicer then the black ones thou I have not seen these in white. Saying that I think the most fun apart from everything being standard in the machines being the very good high light output, very easy to maintain and being well made. Is the thought of doing change over’s.

I did think of going down the route of converting just one so that It can take larger reels for a hours worth of film. Thou the cost for these long playing arms with torque motor will set me back about £600 pounds which is a bit steep. So I think I will stay with the change over system for now.

With the machines only coming with out the new exciter lamps. I am sure you can request them to include the red cyan reader at no extra cost. But maybe things might have changed. I do know of company that sell these converters where all you do is just change your existing bulb and use the LED type which uses the same bulb base fitting as your old one.

Also another factor you need something that will boost the sound output from the LED as the voltage and brightness will be considerable lower.

Anyway let me know how you get along If you do decide to go down that route of DIY using red LED’s. It would be good to find out how to do this myself even thou at the moment I only have a handful of trailers with the new Cyan track.

Robert, if you decide to go for a long play unit, let me know. I have here an additionnal set of spare parts necessary to build a Cinemeccanica tower : main motor, reversible cycle controller, top feeder spindle assay, bottom take-up spindle assay and floating hub 12 000 ft - for two hours - take up reel.
All you need to add is a frame (The one I used to operate was made out of wood, so it's quite easy to build), a set of belts (one v-shaped, one toothed) and some power cable.
I'm selling this set for 350 euros and even with s&h, it won't be 600 pounds...

Have a look at the "Xetron/Cinemecannica "Tower" DGB film transport" manual from the Film Transport paragraph of the manuals section.

Sounds right up my street as I might be interested in this, as I would like to build something where the reels can be both underneath the projector if possible as I need as much space to go back to still get a good big picture. As most Long Playing Tower Units are only really designed to play behind a projector.

I assume you could use this to your advantage when making up and breaking down a 2 hour feature?

The only thing I will need to find is a set of belts like you say I assume one being for the take up motor and timing belt. I suppose the other thing is to make sure that the design is right frame wise and that it can take the weight. Just had a thought I wonder if wood from a pallet would be any good for the design?

Robert, I disassembled mine as it was bolted to my wall. I used treated construction wood, it's 30mm thick, plus 30mm wood beams for reinforcement and metal bracing. I also used the same material to build my set of tier seatings.
The catch is that it's really meant to be used on a tower system as one motor drives the whole thing and there's a clutch on it that will either engage or disengage the belt pulleys.
With the clutch in one position and the cycle controller set to 23 cycles in forward, the motor will have the right torque to take-up the film. Clutch in position two and controller set up for 50 cycles in reverse, and you'll have the torque to rewind and disassemble prints (you need a platter or a split reel in 12.7mm)
There's also an anti-rollback contraption (it needs a strong spring such as the ones found on folding couches) on the feeder spindle.
Your idea of coaxial reels is great (my new IDEF film transport does this for up to 15000 ft of film), I just don't know if it's feasible with the Cinemeccanica parts. Hope everything is clear.
Check out the drawings on the manual.

But we are wandering way off the 8mm subject so, if you want we can continue this discussion via email off the forum.

I believe Proyecson make this machine an exact copy but under their name and their ones come with 6000ft arms with that extra take up motor, also they (the projector) can be mounted on their long play tower that takes 12000ft reels.
I prefer changeovers as if you are only going to show a feature once you do not need to muck around makeing up films, but it you were to use them in say a commercial set up a long play tower would be handy, Also I like doing changeovers as it keeps you busy in the projection box!
I believe that the Spectras use a switching type set up in the rectifier that switches the lamps for both machines on/off when a changeover happens. What shutter do they use the look like a drum shutter but I could be wrong. [Smile]

Some pics of your beasts Robert wouldn't go a miss! [Big Grin]

There is an interesting set of links to Chinese 16 & 35mm projector manufacturers on this page if anyone fancies a look. A couple of the links are dead.

I get your point Pat and I think for the extra cost I will stay with changeovers. I just need to find another good quality cheap short throw lens for flat projection and I will have justified having two machines. Yes Proyecson in Valencia, Spain makes these projectors along with 6000ft arms, which look very nice. You have choice of many long playing set ups as well as a fully suitcase style portable long playing machine which looks very professional.

Yes the switching type that the Spectra’s use is controlled by the rectifier. As soon as you press the other Xenon light button on top of the projector. It steels the voltage current away from the other projector that is to run out of film so that your second projector will light. Also the clutch plays a part in getting the cue marks set up just right before switch over. Yes from what I can tell it is a shutter drum that resembles a ducks beak when in rotation.

Don’t worry Pat pictures will be posted this weekend so you have a better look.

Rob.

Hi Michael.

The throw i have is about roughly 35ft, at the moment i use two lenses one prime lens for scope which is 80mm f2 and a 50mm f2 that fills a 12 ft screen very easily.

Can't believe how bright it is and i can't wait to use them in the back garden in the summer!

Some more pictures of this beauty

Thanks for the pics Robert
Those machines are great! I better put my order in for a set!! [Big Grin]

[Big Grin]

Can you use normal 2000ft reels on the machine? I ask as all the pics I have seen show the film just like you have it running from a core to a core....
I hope you are pleased with them!
How are the aperture plates changed??
done any changeovers yet???? [Big Grin]

Hi Pat,

Have not actually used 2000ft reels as most of what I have is on cores, which makes life so much easier and keeps the film in top condition.

But I am sure you could use 2000ft reels with out a problem though not sure of the spindle size if they are 9.2mm standard European size or UK-US size.

Now the aperture plates are dead easy to change just a case of slipping them off and putting them back on. Also the springed-hinged gate comes out completely for easy cleaning.

Have not tried the change over process yet but when I do I will let you know how I get along. It sounds pretty easy mind you, plus having a clutch is probably a good thing so you can line things up just nicely for the second cue.

Best,

Rob.
