Lens Board Light Seal: Felt on Steel

[rshepard]

I've modified a Cambo 4x5 lens board to accept my lenses mounted on the Galvin-size boards. The last step is to glue felt strips on the edges of the center hole so light does not leak behind the small lens board into the camera interior.

I'm wondering what glue or adhesive I should use to attach fabric (black felt) to the steel lens board. I don't want the adhesive to soak into the fabric and make it stiff; that would negate having a flexible felt layer to block light.

Any and all suggestions greatly appreciated!

TIA,

Rich

At a sewing/fabric store, you can buy sheets of felt with an adhesive backing.

Just take a scissors to it, pull off the backing, and stick it on. ©

At an arts & crafts store, you can buy sheets of 2mm thick foam with an adhesive backing. The brand name is "Foamies". Just take a scissors to it, pull off the backing, and stick it on.

If you already have the felt, there are double-sided tapes that could work.

Rich, most probably you don't mean felt but velour.
Anyway a good cement for such cases is a contact adhesive. as it won't be sucked into the plush if sparcely applied. Over here you can get it in a less honey but more paste-like version, that will even be sucked less. But any glue can easily get messy with strips of velour, by glue reaching the plush side via your fingers. So consider laminating double-sided adhesive tape to the velour and then cutting the needed strip with a sharp knife.

Thank you all. Self-adhesive foam was just too simple a solution; that's why it didn't occur to me. :-(.

And I do mean felt, not velour, AgX. I actually know the difference. :-)

I like the foam idea as that will provide a better seal than would the felt with double-sided tape.

I've found a cheap yet very effective solution, I use the felt light trap from film cassettes, when carefully pulled from the cassette after opening it up, the reverse side is plastic coated, which takes a contact/rubber cement or double stick tape very well. The pieces aren't too big but are often just the right size for sealing small projects.
