Slitting film precisely (lengthwise)

Steven;

Ever try to clean up a spill of gelatin from the floor? Especially nice to try when hardener has been added! Or, try to clean the dirty cold equipment after a run? Or, when things go wrong, try to "unclog" the coating machine or the slitter or chopper?

Hahahah. I could wish these on my worst enemy but not on any APUG member.

BTDT.

That would be interesting for sure.
I've read a thread, on another forum, where an ex worker of Ilford mentions how the control room for coating operations is:

Sounds interesting. That machine must be huge, heard something about 100m long.
I'd like to visit the factory someday (5-10 years). It's quite close to Manchester as far I know.
 
Ilfochrome was / is a positive color product that was once called Cibachrome. It is manufactured by Ilford in Switzerland.

Ilford in England did make a color negative film for a short while.

Huh, OK. I had some older 220 film I shot and I was annoyed by how thin the film base stock was, so decided to just stick with 120 instead. Now I need to go dig that up and figure out what was really going on...

Finally dug it up... With a digital micrometer, it measures .013mm thick. Some nearby similar 120 film measured .012mm thick (i.e. the 220 was imperceptibly *thicker*, not thinner!)

So who knows what the heck I was thinking. I remember HP-5 in 72-exposure rolls being ridiculously too thin to work with, but clearly I'm just confused in remembering that 220 was also like that. Sheesh. Time to go shoot the rest of that brick I have of 220 rolls!

Please excuse me as I bring up this old thread.
I have been given some infrared 12 inch wide film for imagesetters. I cut a piece of it and develop it, seems ok.
I looked at the links at the first page it seems pretty straight forward to build a slitter to get this to a bunch, I mean 5 rolls for 120.
Has any of you done with such wide film?
 
I slit film all the time for my Minox's. Delta 100 is great and Delta 400 is good for low light - but a little grainy in Minox format.
I don't have trouble with stress marks or dust. I am very careful how I handle the film and use an anti-static cloth when loading the cassettes. You can see some results on my web site. I use an Al Spoil slitter from Goat Hill. Uses razor blades easily replaced. I modified a paper craft punch to put a hole in the ends and build a measuring board to cut film to length. Works for me.
 
heres a guy that just may be able to help everyone.......
