The above images are screen shots from a computer generated animation of the Century projector head. I have been working on this project since Feb and aim to use it as a visual rep for training. All moving parts are functional and there is also moving oil in the intermittent, a xenon light beam and the film progresses through the mechanism. MAybe it would be a fine addition to the video section?

Very nice! Talented chap.

Just a small point, the fibre gear driving the intermittent looks like the shutter drive gear, remember the intemrittent drive gear slides on it's keyways and as such is one of the most crucial points for cleaning and lubrication on the whole mech.

Hi Tommie!

Very nice work! What CAD software are you using?

I would be careful of a couple of things, though. You copyrighted YOUR work...however, if you tend to make $$ from this work, then I would check with Strong for their approval to ensure that you are not infringing on their copyrights!

Your work might be interpreted as "reverse engineering", and this is a very touchy subject in todays world of manufacturing! Just don't open yourself up to trouble.

Regards

Will Kutler

The Century gear train dates back to pre-World War II so probably any design copyrite is long expired.....Cinemeccanica France did a digital animation of the V-5 projector some years ago which where pretty nice.

I can't see any copyright infringement in the slightest...even if it was a brand new projector. The image is an artists' interpretation of the machine...it is not an ACAD drawing on the manufacturer of it. The sprocket drive gears, for instance, do not really represent the sizes and pitch. It doesn't matter for this sort of illustration.

Now if Strong (or anyone else) had made this very same drawing and all Tom did was animate it...then there could be some issues.

Reverse engineering is indeed a fine line...generally if you come up with the know-how without looking "inside" you are on the right side of the law but proving what you knew and how you came by that knowledge could keep you in court.

For things like software/firmware, one has to copy the source code to really infringe. Anyone that has coded knows there are limitless ways of writing a program to do the same thing...just some are more efficient and reliable than others.

Jeepers, that's nice work! Sure beats the heck out of the little models in my animation.

FWIW, I think if Strong already had an animation resembling this one, then Tommie would be mired in a copyright infringement issue -- of the animation. He's not making a prototype of the machine. It's artwork.

So, they corrected the shake? [Smile]

Mr. Evans,

I would like to see it in the video section if Brad would like to post it.

Posted by Tommie Evans (Member # 2674) on 05-29-2006, 08:49 AM:

Ok, I'm using Cinema 4D V9. . .
Here are a few screen shots from the video to wet your appetite!

I wonder if he could make a similar video of a Simplex or Brenkert. BTW some fictional Brenkert model numbers if Brenkert was still existent:-BX-870,BX-80AT2E (all electronic with built in soundhead & automatic dual lens turret) BX-1570,BX1570-I (IMAX) BX-870 & BX-1570 referring to the film format while the BX-80AT2E is 35mm.

Absolutely beautiful. How about a DP 70?
