Elmo GS1200 Scratch Parts Required

[Robert Curtis]

I wonder if anyone might be able to supply some replacement parts for the notorious scratch points on GS1200's, please? I am searching for the full assembly of the film inlay and auto thread lock (numbered 1, 2 & 3 on attached picture). If anyone might have some spares available for purchase, I would be very grateful! I am aware Van Eck produce the film inlay (No.1) which I have purchased and fitted. This cured the scratch issue for a while but sadly I don't think this is the part which is producing the light tramlines, so I am hoping to replace the whole assembly. Thanks for any help!

Contact Van Eck Video Services. They have new updated parts for this issue. It appears they have all the parts you numbered here. https://van-eck.net/onderdelenzoeker...type=GS%201200

Thanks for your suggestion, Shane! The Van Eck parts are only for the Mark I model and my GS1200 is Mark II. Plus I understand the part No.2 in photo has not been successful due to the course sandpaper texture of 3D printing hence Van Eck part being unavailable But thanks very much for your valued suggestion!

Robert, the film threading guide is best replaced by the chromium plated steel guide sold by Wittner's. It is expensive, but it will never wear down or scratch your films like the Elmo OEM plastic guide. I got one for my GS1200 and it is really beautifully made with a mirror finish which must be less than 5 microinches.

Robert,
it is so sad that Elmo used too many plastic for this great machine.
I sold my Elmo years ago after too many „sad surprises“.
After updating parts 1-3, I sadly found out that my additional scratch problem came from numbers 5 and especially 7!
So take care that You keep in view these parts, too!!!

Fitting rollers in to the worn guides is another very good option, and may be the only solution for guide 2.

This is what I did a while back, to fix it once and for all with some spare bits and pieces.

Here are a mix of photos taken at the time while attacking the projector, regarding another area of wear that later models like this one with a fwd facing bottom loop you wont need to do anything in the sound head area, only the early models, with a rear facing bottom loop, will give you wear problems in the guide near the sound head.

The projector has been running like a swiss watch with not a sign of any scratching, so that should do it for another 40 years

The best thing is to do it like Graham. I´ve done it about 28 Years ago on my two machines and it is still running until today.
