Hi all,
I am trying to join my notched films together using my cement joiner, but it won't do the job! I even tried using super-glue and that wouldn't hold either!
All my normal titled 9.5mm films join well.
What's going on? is the film on Notched titles a different type? It's got me stuck on how to join up lots of the Notched titles.

What's the story guys????

Cheers,
Clinton

Hello Clinton,I don't use 9.5,but your problem fascinated me.
I would assume that 9.5 is acetate base,the thing that gives me
cause,is that Superglue won't adhere.Now way back in the early
'80's when the second 400' reel of "Star Wars" became available
it was released on polyestar stock which meant that ordinary
acetate solvent wouldn't work,not having a tape splicer at the time
I resorted to using Superglue.Both edges of the film must be
scrubbed on your cement splicer and any debris blown away,the tiniest amount applied,the best method is to use a
sewing needle with the end of the eye nipped off and that
should deposit enough of the adhesive to the area,ensure the
area is wet then clamp the jaws together and leave for a couple of minutes.The film should be well and truly fast.You might
need to tidy any excess from around the edges,but I think
you'll find it should last.The splices I made on the "Star Wars"
compilation have still held up to this day.Always make sure that
the edges are clean and free from grease etc.I hope this has
been of some help, good luck and keep us informed.

Hi Hugh,
A film friend of mine suggested the following-
"I understand that some 9.5 (and other sizes) film has a coating on both sides so you need to carefully scrape both sides for a good cement splice."
And he might be right , I decided to give the project a few days off [Smile]

and will see if he is correct.

Notched film I presume would have to be tough as they are paused for the title eh?

Hi Clinton,when you come to splice your film,I'm assuming that
you are using a cement splicer,both films to be spliced are in
the splicer and the end of both pieces of film must be scraped
with the scrapers on your splicer,not too much,just enough to
remove the emulsion on one side and to rough up the base side
on the other piece,usually then film cement would be applied
or a touch of superglue,with film cement the trick is to use just
the correct amount,too little means the splice will part and too
much means the splice will warp or bend.Try it on a piece of scrap film until you feel confident to do it on your precious
movie.Best of British.(luck that is)

Yeah I have done heaps of this stuff but it is only the Notched title films that recently got me stuck!
Will do it again with lots of thought.
Cheers,
Clinton

Hello Clinton. I wonder if you have someone near you with a 9.5 tape splicer who could help out?

Hi Lee,

I managed using a combination of different tape splicers - all done and I learnt something new.....

Cheers all

Clinton, I have a very hard time thinking that your notched films are made of polyester, because I am pretty sure they did not have that film stock in the 1930's. Every notched film I have ever seen has been diacetate film which would accept cement. Are you sure it is not splicing leader to the film that is the problem? Because the leader would probably be estar. You of course know that you will need to scrape all of the emulsion away or else it won't join, and it is possible that the film might be curling on the edges that is preventing the film making a secure contact for the cement to cure properly.....The best advice for splicing 9.5 is of course using tape because knowing that there will never be any more made means you don't really want to lose any of it...

Hi Dino,
I think it may be a combination of some of those thoughts, the cement did hold the joins in some cases and I used a tape joiner for the others with mixed results, only because I don't have a actual 9.5mm joiner machine, I had to do it using a combination of different tape splicers I have.
Oh and they were really curely at the end of the films!

The results were FAIRLY good. I will keep an eye-out for a 9.5mm tape joiner to redo the joins but I think they will be VERY rare eh!

It is deffinately a case of the right tools will do the right job [Smile]

Cheers,
Clinton in New Zealand

P.S. Yeah these films are rare so I always save as much of the film as possible even if the titles are missing etc.
And even if the films are worn or scratched it doesn't worry me at all as I think that is the charm of this GREAT hobby! [Big Grin]

Hi all,
well i was still having problems joining these notched films with good results,but this week i finally have it sussed!
As i don't have a 9.5mm tapejoiner i used my cement-type joiner to get the film cut with the exact space between the perfs and then used my 16mm tape to join them, and then using a very small screwdriver heated to just make the correct new perf and it works perfectly with no pic jump etc.
I my case it paid for me to experiment and workout what i needed to do to allow me to work with what i have...........

Hi Clinton, re joining notched title films. The tape splicer is the answer to these. The only 9.5mm tape splicer I know of is the one made by CIR and it is quite expensive and few and far between. Many years ago I had the difficult job of joining about 900ft of 9.5mm home movies shot in the 1920s which had to be removed from the little 30ft metal cassettes. It was like trying to join dozens of watch springs together and of course also had lateral curvature. This was pre tape splicing. The base of all these earlier films were diacetate. I found that some of the more recent film cements are formulated for tri acetate and do not always seem to work so well with diacetate.
