Metal picture frame kits have four pieces for the sides and hardware to hold them together, usually plus the small springs. I've also made wooden boxes and just either screwed or epoxied old 4x5 roll film adapters. You can also make a wooden support to which you attach at the front whatever you've put together and at the back, either permanently or with tape, a readyload holder or polaroid holder. The pre-anniversary model speed graphic has a perfect 4x4" lens board that you could do a lot with. They come with stops on the rails that limit bellows extension, but if you remove the stops you can get 12" extension. You're limited to a minimum of 3" extension. ----- Original Message ----- From: Colin Talcroft <ctalcr...@yahoo.com> To: <pinhole-discussion@p at ???????> Sent: Sunday, April 08, 2001 11:28 AM Subject: [pinhole-discussion] Camera backs
