My Ferrania Regular 8 splicer can no longer cut the adhesive tape, perhaps the blade does not work anymore.
Problem solved with the repurchase of the full splicer, which costs less than 30/20 euros, but if there is any useful advice ... [Smile]

I tried with a sharpening stone, but the blade is too thick for that kind of maintenance. And the spare parts are very expensive.

Once tried "fixing" my CIR splicer (35mm film gauge,of course) trimming blade by filing down its edge to the point that I can easily slice the paper with that blade. Guess what? still didn't work! [Confused]

Later found that I had to realign the blade to make it just touch the matrix edge,to make it slice the splicing tape efficiently by it shear action. Took AGES and countless attempts to just make it work,sort of. [Frown]

(still some tape excess hanging off sometimes)

I've found that the CIR's do get gummed up with the adhesive from the tape and it does make them less efficient. Try stripping it down as much as possible and clean everything with an alcohol based cleaner.

I have the same issue with my CIR splicer, often having to trim the edges with scissors, and one part gets no tape on it, even though it's covered before I depress the handle.

They are great when working as they should. When you think about it, the amount of tape you throw away after each splice is larger than the amount used to secure the film.

Ah, so it's a known problem. I will try to clean and realign the blade, hopefully good.
It is inconvenient to cut with scissors, you lose the good effect of the cut.

Let us know how you get on Luigi, then I might try the same thing. I don't like using scissors as you have to be careful you don't clip the film.

I solved a bit 'thanks to the advice of Terry, cleaning the blade well with alcohol, but I also moved slightly the blade with a nipper: I tried to make the blade go very parallel to the matrix as Nantawat said. But I believe that the cleaning had the most effect, there were tape residues.
Now it's better, but I have to give a strong shot anyway.

I also saw the spare blade, costs about 25 euros. It is not so much, but the splicer, as mentioned, has the same price.

I cleaned my blade up some time ago but made no difference, that only leaves bending it slightly. On Ebay I've seen new blades at £40.

get an oil sand stone what you sharpen chisels with and spend 10 mins or so then you will be able to have a shave with it like I can when I sharpen my cir blades and chisels

Robert, here it costs much less:

This is for Super 8, I suppose also compatible for Regular 8, eventually possibly can ask. [Smile]

David, I have an old sharpening stone, but even when I wet it I did not get any results, maybe it lost efficiency, too old.

Oh,one catcha here.
While you can remove/replace the blade in 35mm splicer without touching the tape punch ass'y,that's not possible for S8/R8 splicer. Which means once you remove the blade,the whole alignments are gone. Then you'll have to realign EVERYTHING again. Probably not a fun job. [Roll Eyes]

PS if only my memory is correct,might have to get a good look again tonight.

Posted by Luigi Castellitto (Member # 3759) on September 13, 2018, 06:29 PM:

True, Nantawat, for costs and fatigue it's better buy it again.
At the moment I have achieved a minimum result with the cleaning, but in the future I will rebuy full splicer.

Posted by Nantawat Kittiwarakul (Member # 6050) on September 13, 2018, 09:52 PM:

Out of curiosity, I had a closer look on my S8 CIR splicer again. It is exactly as I thought.

The whole upper ass'y (perforater&trimming blade) are held together by 2 screws. Although you only want to replace the blade,the perforater will be knocked out of alignment too. Certainly a thing could only be done when you have enough time&patient. [Roll Eyes]

Comparing to a Russian-made 35mm splicer which happened to lying around on my desk at the moment.

The whole blade ass'y could be removed for cleaning&inspection with ease,no tools required,and no realignment necessary,too. Something Italians couldn't think of. [Wink]

when you say you wet it with what should have used oil
