Hello,

I am looking for a spare part for the Elmo GS1200 . Its the sound pressure Pad roller lever.

Highly appreciate info on the availability of this component.

Kind Regards,
Mathew

Hi Mathew,
I am a newbie here in this forum and I had just the same problem like you. I recently bought a GS1200 with sound problem due to the cracked pinch roller lever. I was not able to find any original spare part so, at first, I tried to repair the broken lever, as suggested somewhere in this forum. However I did not get a good result, because the plastic was fragile and cracked in two places.
Then I changed my strategy, I drew a 3d model of the lever, trying to replay the Elmo Gs1200 Mk2 improved lever design. After that, I printed it in black ABS plastic with my home made 3d printer. I also recovered, from the old lever, the rubber roller, its axis, the snap rings and the two allen screws and mounted them on the new one. The result seems to me quite good, but, above all, it works! My GS now has found again its original sound with no failure.
If you don't find somewhere a new spare part or you are not able to repair the old one, I could reprint a new lever for you.
Regards, Renzo.

The cracking of the pressure pad lever is very common on the earlier GS1200'S. Later models had a cylindrical metal sleeve bonded into the part to eliminate the high stress on the plastic.

My first GS-1200 was an earlier model and the lever was cracked and had been repaired with glue, but it was a poor repair job and would not hold.
I was lucky to buy a new part with an integrated metal tube from a well-known person.
This is certainly a problem point and perhaps Edwin could investigate a new replacement part.

I agree, an excellent piece of engineering!
When you look at the crack on that part, and how it was designed, you have to wonder why anyone at Elmo thought that it would'nt crack!

That is really excellent - well done indeed and welcome to the 8mm Forums.

I don't think Edwin needs to make these it looks as though Renzo has 'cracked it' already (pun fully intended).

Hi Renzo,

Fantastic.

I am currently managing with the glued option as mentioned by Maurice, but the alignment keeps slipping off even with the hex nuts in place.

I am awaiting some response on the availability of the same. I will let you know and PM you.

Regards,

Thank you all for your welcome and gratifying words.
As you well know, necessity is the mother of invention (and the Italians are known as a little masters in the art to make do).
I was not able to wait too much time before finding an original spare part. I longed to see my "baby" working sooner as possible.
But now it's time to briefly introduce myself in this forum, a rich mine where I have digged and learned a lot about our wonderful hobby.
My insterest ranges all over the smallfilm world: I collect S8 cameras, 16mm/S8 projectors and films, equipment for film developing and editing and all sorts of inherent documentation.
Even if I own other high end projectors I am a Braun Visacustic addict. I found them among the most rationally built S8 projectors. They are compact and reliable with a lot of functions and accessories.

To Mathew
If you need a GS1200 roller lever substitute, now you know where to find it.

To Maurizio
(an italian friend, who I personally met twice for joyful debating moments about our common hobby)
For sure, my printer is looking forward to warming up ... I am going to send you a mail for details.

To all the Others
Thank you again.

Renzo

Is no one going to mention that Renzo said he has a HOMEMADE 3-D printer? That is what I am most impressed with [Eek!]

Hi Mathew,
nice to meet you again and thank you to remember the first project I presented in this forum. For sure I am going to contact you by PM.
In the meantime, to meet the request of other forum members, I have improved the pressure lever design, inserting a brass bushing on the hole where the lever is fastened on the rotating axis. Now it is just like the last Elmo lever design.

Chip,
the dimensions of my printer don't allow to produce a so big reel. Furthermore this kind of objects can be made only by 2/3 single pieces bonded together in a second moment. I think it's not worth of it because the cost could be much more than to buy a used reel on the net.

Dino and Steve,
nowadays it is not a big problem to build yourself a 3D-Printer, you can find a lot of good and detailed projects in internet. The main difficulty is to realize a precise 3D model drawing. Then all that remains to be done is performed by the printer software.
Even if you don't have a printer, but you have the file of the 3D model of the piece, there are a lot of services in the net that can print it for you, with several kind of materials, for a few bucks.

Renzo

Renzo, if you intend to make a few of that lever, as above with the brass insert, I would be a customer for 2 of them. Make your price one that rewards you for your efforts. I am sure many members would be interested.

Very likely so, David. To double check, run a film of known sound quality and gently press the pinch roller holder right above where the roller istself is dastened: you should hear anobvious improvement...
