Camera Building - Self-Adhesive Velvet

I still need to make pivot hinges for the two outboard pulley blocks on my 4x5 KAP camera. While cruising around for small hinges, I ran across something really neat at Rockler: Self-adhesive velvet.

They sell it as a box liner, but one of the colors available is black! I can't think of a better way to line the inside of a handmade camera. It would act as a light blocker (velvet is typically pretty opaque) and it would make for a very non-reflective surface inside the camera. Perfect!

The only caution is that the adhesive they use is insanely strong. So once it's on, it's on. One of the reviews advised thinking through your handling methods carefully before using it. They were making sixteen boxes at once, and said the first one was 100% learning experience. The rest went smoothly. Their solution was to use pins and a pocket knife as positioning tools. The adhesive apparently sticks to finger tips like glue. In their words: "Think of duct tape adhesive on steroids."

A 12"x24" sheet is $8.95. That's enough to do the entire inside of a 4x5 box camera. Not bad considering the plywood to build the film back is easily twice that.

Probably not for this camera, but I know there's a next time. I'm already working on the design.
