Open the pictures in "paint" and re size them to 550 pixels or less in the biggest dimension.

Jpg photo's are fine to post here.

Once re sized, you'll be able to post them here Phil no problem.

Hello Phil. On my version of "Paint", you have to options in the resizing (redimensionner) section : percentage and pixels. It is automatically set on "percentage", so I dowmnsize from 100 to 10 without having any idea about the picture size.

A new projector of any description will cost. My question is, who will actually buy one. Most of us have excellent machines so we won't be shelling out in the near future. So how many will actually buy in to the concept? Phil Sheard made a valiant attempt that was little supported. He has a big enough problem trying to produce new prints let alone sell them. Perhaps a line of refurbished machines might be worthwhile but folk like Kevin Brown can supply from whatever he has available at the time so we have sources. The age of many of us is against further purchases so I suspect the enthusiasts for this idea may be extremely small. It comes down in the end to money and it's a brave man who will go up the route of investing time and money into something so uncertain. And, I've never had a problem with auto threaders. On a well maintained machine they work fine.

Phil, first, click on "Click here to upload an image" (below the space you're writing an answer to a message). Then you end on another page, go at the middle on it and at the left side you will see two empty spaces : one for your name and one for your password. If everything goes well, when you type the first letter of your name, the full name appears and so does your password (if it doens't do that automatically on your computer, you have of course no other option than putting these informations manually). Click then on "parcourir" (it appears in French on my screen, I guess the word "browse" appears on English speaking computers :-) Then choose and open a picture at the right size. The preeceding page appears again. Click on "submit" (maybe my computer doesn't know the translation as it is written in English) .A new page should open telling you if the picture is accepted or not. Just copy the address (seen on the top side of the page, above the picture) and then paste it in your message space. That works with me.

Interesting thread this; I thought I'd share my two cents:

I've toyed with the idea of modifying/making my own projector for a while, and I have established a list of "demands".

1) It would have to be LED-based to get a brighter and "whiter" picture, and of course to avoid expensive and shortlived bulbs. Using LED would also make it more economical in terms of power.

2) It would need at least 1200' reel capacity.

3) It would need an EQ and mono/stereo output using 3,5mm jacks.

4) It would need variable speed control.

5) It would have to be lightweight and portable.

--------------------
Well who’s on first? Yeah. Go ahead and tell me. Who. The guy on first. Who. The guy playin’ first base. Who. The guy on first. Who is on first! What are you askin’ me for? I’m askin’ you!

High Christian,

1) Yes !!! H/P led or Arc Xenon , U/V fltered......
Led is th e future because of extra life duration and less expensive than Xenon bulbs (to be studied)
2) Yes !!! Expect directly 750m spools , no change on the price, just the arm lenght a bit longer
3) Yes !!! ....and Minimum Electronic dedicated to sound inside the machine. Electronic protected by a shield due to Xenon Ballast (if used)
4) Absolutly ! 25 F/S Electronic regulated for Video Transfer
5) Hummmmmm..........Afraid that machine should be something like 15 kgs , (Plain Aluminium Structural parts, and heavier is a machine ....... Soft running is the machine )

Chris : What about experiencing Digital sound recorded insteed off usual Analogical , each track 1+2 carrying the same signal in the aim to increase sound reliability in case of main track fading out.

Then it should "very exiting" to introduce a Frames driving by a small "Malt Cross" , to be dtermined (Full Mehanical or Electronic with Step to Step motor). That needs to abandon the idea of a recording machine to save space below the lens carrier.

A quieter design would be a big improvement, but as said above, we're dreaming :-)

I assume the best way to keep Super 8 "alive" is to bring something new , associating "past" experience and new technologies.

1) Modular Concept, cunning ideas to save time and money ....And easy to maintain by the owner Himself.
2) Using Best industrial solution
3) Using New performing material

I have seen same "Prices" for machines (Ouffff.... more than 3000 E, imagine what you can do with...).
The machine "imagined" has to be .......definitly below that price.

I would say that right now, the emergency is to have a good reversal filmstock at reasonnable price. Ferrania is working on it but time is against us.

Phil, just in this past week, ive managed to get the shutter claw noise on my Beaulieu below the exhaust fan noise for the very first time since my ownership. So these already can run very very quietly with some tenative fine tuning and decent silicone cam grease.
not as quiet as the Bauer due to the more powerful fan and open gate design, but very quiet nevertheless.

Mmmm...Best leave that one there, I'd say.

Ugo's write up on the other forum says it all!

Quote:
Hello Hugh,
"I don't fit rollers, I modify some path parts. That's enough. I agree with you: the gs1200 is very dangerous for the films, but to modify the machine is possible".

I'd say these machines have already been reinvented!

....................................................................................................................................................................................
Back onto Phil's photo's,

I like the knurled spindle holders featured there, these seem very well engineered as also is the rear roller modification though I have no idea for it's necessity, as the original one works fine.

Equally I cannot really see how the hole drilled in the sound head presser arm would have ever been able to accommodate all the required photocell and exciter lamp and lens parts required to ever have enabled this part of the project to have ever been realistically viable?
I'd need that one explaining to me I reckon.

Well my GS1200 ain't dangerous to my films and I have been running Super8 through it for the last 25 years [Wink]

Sure some parts wear out over time, but those are simple enough to replace, that goes for "all" film projectors.

The most reliable projector ever made is still my trusty ST1200 "M" model, that's now 40 years old....and its still going strong.

Elmo really made a good product and am sure the design teams that built them way way back in the 1970s never expected them to be still in general use, all these years later.

As a machine Graham, the ST1200 is reliable. As for it's use as a film projector, well in mine and many other peoples experiences, that is highly debatable if you value your film collection.

As with almost any machine out there, one mans pill is another mans poison.

I'm only glad I discovered the machines I did, when I did, or else I'd have been out of this hobby for a second time not long after entering it again.

Andrew, I didn't know that expression "One man's pill is another man's poison". However, when looking to see if there was an equivalent one in French (which I didn't find), I noticed that the Net gives two versions but they are both different from yours : "One man's food..." and "One man's meat...". The "pill version" is better :-)

Some interesting mods Phil, did you modify the plastic guide under where the lens gate swings out, its fixed with a Philips screw hidden inside the lamp housing. I was cleaning my machine and noticed this was accumulating a lot of oxide residue from films, and because it turns the film through 90 degree's into the sound heads must be cause for some scratching of film if left unattended. The take up spindles are not a good design on these and prone to brake, Elmo has the best idea an that, a plain spindle, one drive pin and a spring loaded clip to hold it all in place, in fact I think the later designed Beaulieu is very similar to it.

I keep having a mystery with my Beaulieu : although I clean carefuly the filmpath and the film, I have a lot (!) of dust ending on the gate (and on the screen). I've just watched a feature (already seen several times, so I will not report it in the dedicated thread) and I had the same trouble. I used several cotton buds with alcool and a duster but the dust seem to have found a secret place to hide. I followed Janice's advice to remove the lens to have a better access to the projection gate. What else can I do ?

Blow it out thiroughly with compressed air anf with the lamp and lens well out of the way. Allow time for condensation to evaporate and parts to return to room temperature before refitting lamp and lens.

clean films before projecting and run through a dry lint free cloth after cleaning to remove any excessive filmguard.

open gated machines sadly will always pick up more airborne particles than machines which cover the gate.

I used a compressed air bottle (and more than generousely !)Maybe I should try next time without the lamp. My films are clean and on other projectors I haven't that problem.

Then with 2 from 3 eliminated, it can only be airborne particles being drawn into the gate then Dom.
