Anyone got any 'old-pressure-plate-smoothing-regimes', hints, tips and/or magic potions to stop the film getting horizontally scratched as it goes through the camera? Emery paper? paint?

Not consistent, seems worse at the end of the film...

REALLY appreciated!

Can I ask? Do you do your own developing?
My reason for asking is I had this problem with film I used on my old SuperME. I asked the company who developed the film and was told the fault was the camera. But I then took another film in, from a different ( new, compact )camera and that came out with horizontal scratches in the negatives, but they didn't show up in the prints.
Getting there! Thanks to you guys

Hi - no I don't (that's next years enterprise!)

Just wondering whether your scratching is taking place inside the camera or the processing machine. I'm pretty sure mine was in the machine. Although the processors denied it.

It shouldn't be too expensive or difficult to replace the pressure plate, or entire back. Which body is it?

Mmmm I've seen that too, and thought exactly the same
This time tho' it is two different cameras(and both very previously-well-loved at that) and two different film processors, so the law of averages says it's prob the cameras....

and, yes, I have found a couple of 'burrs' on the plate since.

The answer MIGHT be a bit of emery paper, and a bit of Humbrol matt paint (plus a bit of lighter fluid for the rollers...) - but I've never tried this before, and thought I'd check around first!

Sorry Peter - crossed in post

ME Super - I did consider getting a spares or repairs but figured the plate might be as bad. Can you get new-ish ones with certainty anywhere?

If you don't fancy doing it yourself I can highly recommend Harrow Technical. My ME-F came back last week with it's dodgy electrics fixed, the sticky foam changed (I know I can do this myself but I couldn't fix the electrics) and generally cleaned, lubed, adjusted and calibrated. I took it out this afternoon and everything worked well and sounded sweet. It'll be while before I get a film back to check, however, and metering in the snow is never easy!

Best wishes, Kris.

Harrow Technical or Asahi Photo. Asahi Photo were able to get a part that i needed to repair a lens, Harrow technical couldn't get the part.

Swings and roundabouts as ever. Asahi Photo said they couldn't get a winder cover for my ME-F, Harrow Technical pointed out that it didn't ever come with one just a black plastic fitting which I had. Both companies seem excellent and if one cannot help, the other probably can.

Best wishes, Kris.
