Here's my findings...It's pretty hard to put too much FG on a film... But you CAN do it.
If you soak the pads when you first put them on, there's only so much they can absorb. Any more than and you'll (1) Make a mess when the FG runs all over the place. (2) waste FG all over the table top, etc. If you soak the pads down that first time and don't add anymore until they are dry, you almost can't go wrong.
If you get some REALLY dirty prints sometimes you'll have to change pads. The print that I got two weeks ago at M.H. College was the worst! I ran the print through the cleaner twice then changed pads. Even though I soaked the new pads, it still wasn't enough to cause problems. What I've been doing most of the time is using the pads from last weeks movie on the 'new' print for those first two run-throughs. Then I put new pads on and soak them. Prints are comming out cleaner than ever since I got the platter bracket. I can speed-wind the print through at double speed. That gives me twice the cleaning runs. The only time I don't use the old pads over again is when they get REALLY crummy...
This week I did have an incident where I was able to get too much FG on the film...
I built the print up and gave it the initial bath in FG, then changed the pads and cleaned it again. I had to leave for a few hours, so I left a note for the Work Study guy to 'clean' the print once more. I forgot to tell him that I already changed the pads so he put on a new set of wet pads. When we ran the print it got really jittery. It wouldn't stay steady in the gate even with the tension on maximum. (Simplex-XL) Even then it wasn't so bad... All I did was stop the projector for a minute and loaded up a fresh set of DRY media rolls. That was enough to 'soak up' any excess liquid on the film. Everything was fine after that.
Brad told me by E-mail one time... "The secret is to be lazy..." -- There's a certain wisdom to that!
PS: I don't have very good access to a digital camera. I have to borrow one from the computer office. Usually it's already on loan.
If I could, I'd take some pictures of the dirty media pads and post them...
Maybe Brad, or somebody else, could take some pictures of some pads in various conditions? (Such as: "Okay to keep using" -- "Time to change 'em" -- "So crummy you'll faint!")
