Restoring Grafmatic 4x5 film holder... : LUSENET : Large format photography : One Thread


I use Grafmatic film holder and the biggest problem is, the light trap felt. The felt wool comes loose and settles on the film leaving a mark. I think because of age the felt is disintegrating and falling apart. I opened the whole thing and cleaned it but, i think i have to replace it sometime very soon. Now, i don't have a faintest of clue what to replace the present light trap felt with. I would really appreciate if someone help me restore/replace the light trap.

Thanks in advance

I can't say that I've had to do that repair (yet). But, here's what I would do if it became necessary. First, look at the website

They carry most camera repair tools and parts, including light trap material, felt and foam core. You should be able to look at the felt coming off and get a feel for the thickness. Buy the appropriate sheet and replace it. As I recall, they also sell glues. You don't want a glue that will emit fumes which might cause a reaction with the film so it is probably best to buy their's or at least note the chemicals in it.
