No not a power cord it's the extension for my Kodak 2D 5x7 view camera. I was giving it a checkup to make sure it's in good working order when I noticed that the rear extension seemed a little loose. I re-tightened the butterfly bolt that locks the extension on and it was still loose. When I removed the extension I found the threaded insert has loosened, in fact it was not threaded into any wood and pulled right out. I fiddled around trying to cement shims in but the brass threaded insert was a bit too small and was not going to be solid unless I filled the hole and re-drilled it to accept the fine threads of the insert. I cleaned out the hole and drilled it out a 1/16 th larger and used a longer insert with a depressed hex for a tool to insert in it without using a bolt. The original brass insert didn't have any way to remove it except to use an easy-out tool. The new insert is as solid as a rock. The original maker did some interesting things in the production of these cameras. You can completely disassemble an 8x10 2D except the riveted fasteners that hold the back onto the rear metal uprights. I'm working on restoring one that I've had for sometime and I had to drill the rivet from the inside to work on the back frame. These projects can be simple or hard and time consuming. It's almost better to make one from scratch than to restore one. Sometimes I wonder why people do it.
