hi there everyone i was just wondering if elmo ever got that promblem fixed with the gs1200.i know that the first version hated cement splices.but what about versions two and three;as well as the xenon one.i know that movie maker(march 1980) stated the will be looking into this via elmo in japan.so when two,three and xenon came out was that little glicth sorted.andy.

Never heard about this one. What kind of problem does the GS1200 have with cement splices? (Assuming they're well done, that is)

according to reports four of the five used to break.dont forget that was the oringial 1970s machine.it was unkind to cement joins in the lower loop and sound section.CZ scientific insruments ltd were the uk distribers at that time.thats why i asked about versions two and three plus the xenon.i would like to think it was sorted out by then.andy.

No, just me. The others have yet to even say anything. [Big Grin]

I might say something if I can find a film with a cement splice in it! [Big Grin]

I wonder if this was the reason why the backwards loop was introduced after the first version?

The film path for the Original Ver1 GS and the ST1200 machines was exactly the same except for the addition of the small rubber roller in front of the sound head. This seemed to be the point where cement joins came adrift and yes it was cured with the revision of the film path on later machines.
For those who contacted Elmo direct about this problem (I was one) they would supply the small green guide as used on the ST1200 series of machines. You simply removed the small rubber roller assay and replace it with the small green guide. This cured the problem of cement splices falling to pieces.
The problem was that this small rubber roller caused the film to go through a very sharp S bend which was a bit unkind to cement splices especially ones which had been made years earlier and were maybe drying out a bit.
My Xenon has the later film path which has a much more direct/gentle layout to it. I have never had a cement splice come adrift to date on this machine or others like it. I have to say however that over the years I have replaced most of my cement splices with Wurker tape patches which go through any of the GS's without ny problems.

The fact that if you contacted Elmo in Germany at the time and would get a free green guide suggests to me that they did of course know of he problem. This wasnt however publicised anywhere and I only found out about this interim mod by chance.

I'm not sure I'm following 100%. Could we see pictures of the old and new arrangements to see in comparison?

Jan, I dont have the two versions to show you. If you know the ST1200'd and the 600's you will know that one has the loop after the gate which comes forward under the lens holder and the other it goes back towards the lamp house. On the GS they also put a small rubber roller in front of the soundhead. I can take a pic to show you the latter arrangement but not the earlier.

Kev.
